Chevrolet Aveo T300 and 24 error codes warn the owner that there is a problem in the vehicle systems. Knowing and being able to decipher the error codes that are displayed on the on-board computer display, you can easily decide what to do in such a situation. In some cases, you should stop moving, in other situations you can continue, but then fix the problem.
A few more words about error codes
Many owners are looking for an answer to the question of what code 24 means. This signal on the instrument panel indicates problems with the license plate lighting of the car.
For such a malfunction you can be punished by a fine, so the malfunction must be eliminated. Let's look at this in more detail. Since the license plate lights are connected to the vehicle's electrical system, you need to check the fuse in this circuit. A separate device is not installed for this circuit; usually it is a side light fuse. It is set to a current of 10 Amps
, so check this device first. However, I would like to immediately warn you that its failure does not always happen.
The wires that supply power to the backlights have too rigid insulation, so they break after frequent bending. Open the trunk and on the left side of the car, check the condition of the wiring. Usually a break is detected by touch, after which you should disconnect the white connector, eliminate the broken wire and put everything back in place.
The situation is somewhat worse when the break occurs near the connector itself. In this case, you will have to disassemble it to replace the wire in the connector terminal. But that's not all. The problem may be burnt out license plate light bulbs. In this case, you will also have to tinker, since in order to replace them, you need to disassemble the trunk panel. Only after this can faulty devices be removed and replaced.
As you can see, problems exist, but they are completely solvable, including with your own hands. Chevrolet Aveo T300 and 24 error codes are far from the only ones; there is also a fairly large list of them. Therefore, it is advisable for all owners to have it in their car for prompt response.
Aveo tidy does not work
Chevrolet aveo ii (t300 / 2011-2015)
Typically, a car rarely suffers from such a malfunction. If this happens, you should look in the following directions.
- The system fuse has blown. You should open the mounting block and find the damaged element.
- On-board wiring can be damaged by vibration and shaking. It is necessary to inspect all wires, terminals and contacts for damage or poor contact.
- It happens that only part of the shield does not light up. This is often caused by the burnout of the light bulbs themselves, which provokes voltage surges within the on-board network. The treatment is simple - disassemble and replace.
- The dashboard itself burned out. This is an exception, but if the fact is established, the entire panel changes.

Problems with the Chevrolet Aveo t300 thermostat
Chevrolet Aveo 2008
Unfortunately, this is not the only problem with this thermostat. The same misfortune accompanies the owners of not only the Aveo, but also the Chevrolet Cruze and a number of other models with a similar Opel pedigree.
After 40 thousand mileage, the antifreeze distributor housing becomes completely unusable
Another problem is the plastic thermostat housing. Its quality and the quality of the rubber seals do not stand up to criticism. After 20-25 thousand runs, the thermostat housings begin to leak antifreeze from all possible cracks. Fighting leaks, as a rule, does not bring success, so the only correct solution in such a situation would be to replace the plastic case with a metal one.
Antifreeze leaks throughout the body
There are also questions about the thermostat valve. In its standard version it opens at a temperature of 104 °C and operates in a cyclic temperature range to a lower limit of 98 °C. In theory, the mechanical valve is installed as a backup device if the electrical part fails.
Interesting on the topic: Troubleshooting: P2008 on Ford engines. Changing the IMRC valve
Standard Aveo T300 thermostat with antifreeze heater. Well, the code for ordering
However, many deliberately decide to buy a thermostat housing without a heater, saving themselves from problems with electronics in the future. A case such as the one shown in the photo is designed for this purpose.
This type of housing does not require the installation of a heater
And so that the electronic control unit does not become indignant due to the lack of a heater, a jumper is installed on the contact block. Electrical malfunctions occur when the radiator cooling fan is constantly on. In this mode of constant operation, it naturally does not last long - the bearings fall apart.
You can install a new fan, but it will suffer the same fate as the previous one if the problem is not radically solved. To prevent the Carlson from working in emergency mode, some changes are made to the firmware of the electronic control unit, which eliminates such problems forever. Yes, many still prefer to install a colder thermostat with an opening temperature of 92 °C on the Chevrolet Aveo t300. For example, Borg Wagner, which does not have a heater.
Metal distributor housing and thermostat housing without heater on engine
This is what we get if we install a thermostat without heating and edit the firmware:
- It is possible to update the firmware to the latest stock.
- There is no need to install a resistor in the heater connector; it is turned off by software.
- The radiator fan operates in normal mode, not in emergency mode.
- The cooling system works more efficiently and safely, which affects the dynamics, fuel consumption and engine life of the Aveo T300.
Instructions for replacing the regulator
Replacing the fan switch almost always follows the same pattern:
- We need to prepare the “ground”. In some cars, this happens as follows: you need to rid the system of cooling liquid if the fan is installed at the bottom of the radiator, or, if the system has enough, remove water from the expansion tank. If the antifreeze needs to be completely drained, then you need to open the heater tap so that there is no residue. Important: do not pour the remaining liquid onto the ground, because antifreeze is quite poisonous.
- After this, you can remove the sensor by disconnecting the connected wires. Then, using the key, you need to remove the housing and unscrew it by hand. The new fixture must be tightened by hand, then a wrench can be used to apply the finishing touches. To prevent leakage, you can use a special thread tape, which will make the connection tighter and more reliable. After this, you can restore the contacts by returning all the necessary wires to their place, and fill the system with coolant.

Number plate illumination error, problem solution
Weaknesses of the Chevrolet Aveo, what about reliability from operating experience
This is perhaps one of the most harmless codes.
Electronics play a huge role in a modern car. However, it may not close completely. The moral of this story is that, after reading on the forum, I almost removed the throttle and disassembled it!
It's electronic on the Cruze, and that's where problems arise. Remember that the electronics of any modern car require very careful handling.
Precisely a smart one with a good scanner, who understands your Chevrolet or Opel, because if you connect a cheap ELM type scanner, then it simply may not detect the error! SO, what problems there may be, I’ll start with, perhaps, the most harmless one: But for a couple of people, after replenishing the antifreeze, the errors went away.
I attribute this to the fact that the coolant pipes pass through the throttle; it can be seen that if air begins to appear there, this causes an error. I did the same, my level was really low, but it didn’t help me!
Error 84 and 89 ABS lights up
The position of the damper is different from the normal angle, the ECU sees this and is visible, so errors 84 and appear. Just clean the damper and everything can be restored! But again it didn’t help me! This can be said to be a flaw of GM. The thing is that the throttle valve, like on many modern cars, is electronic. If you remove it and this is quite an undertaking - remove the side cover of the control unit, you can see 4 tracks and 4 contacts that go along them.
However, for some it didn’t help and they have to order a new throttle. As I understand it, if not everyone is pressed onto the track, then the error will not go away.
But it’s really difficult to do this; it’s almost a piece of work. Therefore, my diagnostician told me that I can try, but this is really not a panacea, anyway, after a certain period of time, it will need to be changed. I want to say right away that the cost is considerable; the Chevrolet Aveo has an original throttle assembly that starts in rubles.
But I got carried away, it’s not the throttle! Almost the same situation as with the throttle.
The gas pedal also has the same block and 4 tracks with 4 contacts. As you probably understood, contact 4 breaks, only at the pedal. The Chevrolet Cruze also performs automatic diagnostics, capable of notifying the driver of various problems. Most often, owners of this model of car have to deal with errors 84 and They signal corresponding problems that need to be eliminated in order for the engine to operate in standard mode again. This error does not indicate a failure in the system, but warns the driver that it is time to undergo scheduled maintenance.
Chevrolet cruze code 84 rpm not working Ecm Change work done in hindi
The electronic control unit informs the driver about error 89, based on the speedometer readings. The following course of action is suggested when error 89 lights up on the display: The driver must check the official Chevrolet regulations, from which it will become clear what specific work needs to be done with the achieved mileage; Next, you need to go purchase consumable components: Depending on the complexity of the scheduled maintenance, the driver can perform it himself or at a service center.
It is worth noting that in rare cases, the cause of the Chevrolet Cruze error is the incorrect operation of the speedometer, which transmits incorrect information about the mileage to the electronic control unit. It less accurately tells the driver what work needs to be done to fix the problem.
This error signals that the electronic control unit has reduced power in order to preserve engine elements.
Car diagnostics
With the release of each new version of a Chevrolet car, be it Aveo, Niva, Lacetti, Cruze or Blazer, it becomes increasingly difficult to decipher the codes, as their number is steadily growing. In order to decipher a combination of numbers unknown to you, it is necessary to diagnose the vehicle: without this there's no way around it.
Chevrolet Cruze car interior
The easiest way to diagnose is to check the messages on the dashboard. In Chevrolet cars, not combinations of numbers, but messages may appear on the dashboard. The owner may not know the translation of the phrases that pop up before his eyes, but these messages are important. Therefore, we invite you to familiarize yourself with their designation. Such messages are typical for the Cruze, Lacetti and Blazer models.
| Message | Designation |
| Change Engine Oil Soon | The engine fluid needs to be replaced soon. |
| Low Engine Oil Level | The engine fluid level is low. It is necessary to check the oil level in the engine and top up if necessary. |
| Oil Pressure Low - Stop Engine | Engine fluid pressure is low. You need to turn off the car. |
| Program Cluster | The instrument panel needs to be reprogrammed. As a rule, such a message pops up after replacing elements on the “tidy”. |
| Service Vehicle Soon | The message warns the motorist that a service is approaching. Usually it pops up when problems are detected in the motor control unit. |
| Vehicle Overspeed | Vehicle speed limit exceeded. |
To learn more about the errors present in the system of your car, you can use a special scanner. This device is a compact computer with software installed in it, designed to check a car on your own.
Diagnostics of a Chevrolet car using a special scanner
There are two types of scanners:
- Universal device. Such gadgets are used at most service stations. Such computers cannot be called full-fledged technical equipment for diagnostics, since they cannot always decipher all the errors present in the car.
- Dealer device. You will not find such a scanner on the open market: it can only be purchased from a dealer. However, these devices can flash the car’s on-board computer, program chip keys and detect breaks in electrical wiring. If you have such a scanner, then you can easily decipher errors in the BC (on-board computer) of your car.
Error 89 Chevrolet Aveo T300
Before talking about which temperature sensor is installed on the Chevrolet Aveo T300, you need to find out what kind of element it is.
The coolant temperature sensor, or as it is sometimes called, DTOZH, is a special device that detects the temperature of the coolant (antifreeze or antifreeze) and, if necessary, sends an appropriate signal to reduce or increase its temperature. When signaled, the fan turns on.
What DTOZh installed on the Chevrolet Aveo T300
Below is a table of temperature sensors used in the Chevrolet Aveo T300.
Each company sets its own price for DOTZH, and this is mainly related to the manufacturing method and design of the element.
Replacing the temperature sensor
During operation of the Chevrolet Aveo T300, it often encounters various malfunctions of the vehicle or its devices. For example, the coolant temperature sensor may not be working properly. This problem can cause engine failure and requires immediate repair or complete replacement.
Causes of malfunction
However, first you need to understand the causes of the problems. Among the most popular:
- The sensor is not installed correctly. This is quite possible if the element has already been replaced and mounted differently in the vehicle structure.
- Mechanical damage. This may be due to poor vehicle operation.
- Short circuit. Interruptions in electrical circuits can lead to device malfunction.
- Open cycle. After the break, current will stop flowing to the sensor and it will not be able to function normally.
Based on the above reasons, we can conclude that most of them are associated with careless operation of the vehicle. Thus, often the fault for not causing an accident lies entirely with the owner of the car and his careless attitude towards his car.
How to determine the breakdown
Sensor failure may be primarily due to a lack of correct digital readings on the instrument panel. For example, if the sensor was installed next to a radiator, deviations in its readings can be quite serious. As a result of such a device, jumps in readings from .40 to 40 degrees Celsius can be detected. The same thing happens if there is a short circuit in the circuit. If it turns off, the sensor will no longer provide temperature reading information.
Description and meaning of error P0597
Chevrolet aveo t300 error 89
This is a generic powertrain diagnostic trouble code (DTC), which means it covers all makes/models 1996-newer. However, specific diagnostic steps will vary depending on the vehicle. Codes P0597, P0598 and P0599 all refer to the engine's electronically controlled thermostat. They are general codes, meaning they apply to all vehicles using this type of thermostatic control, however only a small number of manufacturers use this type of system. So this trouble code article is basically identical for all three codes. The P0597 engine code indicates that a fault has occurred with this system where the control voltage is non-existent. For the most part, German manufactured vehicles like BMW, Mercedes, Audi, Mini, Volkswagen, Opel and Jaguar use this system. An electronically controlled thermostat consists of various temperature and load sensors, a computer program and a control housing with a built-in thermostat. ConceptBy monitoring coolant flow or engine temperature electronically, the throttle part increases fuel economy and reduces emissions, while reducing temperature under load increases power.
DTC C0242
| • | Before you begin diagnostics, see Diagnostic System Check - Vehicle. |
| • | For an overview of the diagnostic procedure, see Diagnostics Based on a Strategic Approach. |
| • | Diagnostics - Procedural Instructions provides general information about each diagnostic category. |
DTC C0242 00:
When traction control is active, the electronic brake control module (EBCM) sends a serial signal to the engine control module (ECM) requesting torque reduction. If certain DTCs are stored in the ECM, the ECM will not be able to implement torque reduction as part of traction control. A serial data message is sent to the EBCM indicating that traction control is not enabled.
Engine running
The ECM has detected a fault that does not allow traction control and sends a serial data message to the EBCM indicating that traction control is not enabled.
| • | During the ignition cycle, the EBCM disables traction control and vehicle stability control. |
| • | The Vehicle Stability Control/Traction Control indicator will illuminate. |
| • | The current DTC will disappear once the diagnostic is run. |
| • | The EBCM will turn off the indicator on the next ignition cycle. |

Injectors
Another fuel element that is susceptible to low-quality fuel is the injector. Clogged elements can cause the engine to run rough. That is why this element occupies a high place in diagnostics.
In order to diagnose and eliminate the malfunction, you first need to remove the elements from the vehicle. Of course, some motorists recommend diagnosing and cleaning injectors directly on the car. But, to perform this operation, there is a special stand for washing injectors.
The injectors are disassembled and the nozzles are removed from them and installed in the stand. First, using different pressures, it is checked whether the nozzle is suitable for use. Then, if necessary, the element undergoes a cleaning process or is replaced with new ones.
System malfunctions
If it was not possible to detect a malfunction in the electronic part, then it is necessary to proceed to disassembling the mechanical part. Thus, the occurrence of the tripling effect is influenced by one of three systems - air, fuel and spark. Therefore, it is worth checking each system separately.
Sparking
In this case, it is worth considering the failure of spark plugs and high-voltage wires. Checking these elements is quite simple. First you need to remove the wires from the car. To do this, you need to pull out the tip of the wire from the spark plug, and the second from the ignition coil. Then, using a spark plug wrench, unscrew the spark plugs from the block head.
Diagnosis of spark plugs is quite simple. First, you should visually inspect the elements for cracks or damage. Clean the contact group with a cloth if they are dirty and install the spark plug back. The high-voltage wire is checked using a resistance tester. Previously, each product should be inspected for insulation breakdown.
Fuel cells
Three parts play a role in the quality process of fuel supply: pump, filter and nozzles. First, we examine the direct injection elements into the cylinders. To do this, they are removed from the vehicle and installed in a special stand, which will show how suitable the parts are for further use. After this, it is worth carrying out the cleaning procedure.
The next thing to check is the fuel pump. It is located in the fuel tank, and can only be reached from the passenger compartment by first removing the rear sofa. After this, the power and fuel lines are turned off. Then, you need to take the fuel pump out and inspect the filter mesh. If it is dirty and clogged, then it should be replaced.
The air filter is to blame.
In the case of the fuel filter element, everything is simple - change it. This part is not dismountable and it is not possible to accurately determine its condition.
Air supply
Another system without which ignition of the air-fuel mixture is impossible. To begin with, it is worth dismantling the air filter element (air filter) and inspecting its condition. If it is too dirty, it should be replaced.
In addition to the air filter, it is worth inspecting the condition of the throttle valve. An element that is too dirty may jam and prevent air from passing normally into the combustion chamber. So, to clean it, you should first dismantle it and then clean it with carburetor cleaning fluid.
Also, after removing the throttle, it is recommended to clean the air corrugation, which supplies air to the damper and the mass air flow sensor. The air flow sensor is equipped with an indicator mesh, which allows air to pass through and regulates the amount required for combustion. A clogged element may result in incorrect readings. The damper, in turn, will not close to the desired position, which will lead to excess air in the combustion chamber.

After some time of operation, owners have questions about what Chevrolet Aveo T300 and 24 error codes are. The on-board computer installed on modern cars is designed to control the car’s systems, and also informs the driver about any problems with the car. This increases reliability and safety during operation, and also speeds up the process of detecting and eliminating faults.
Chevrolet Aveo T300 and 24 error codes warn the owner that there is a problem in the vehicle systems. Knowing and being able to decipher the error codes that are displayed on the on-board computer display, you can easily decide what to do in such a situation. In some cases, you should stop moving, in other situations you can continue, but then fix the problem.
Cheap solution, my problem
I didn’t specifically combine them with the first four; I want to dwell on my problem in more detail. One more warning - before you get into your brains and electronics, let’s remove the battery terminals!
In general, my diagnostician was “from God,” as they say in Chevrolet and Opel, “he ate the dog,” he even worked for the officials for a year, but then he was laid off (GM left Russia). He has a professional scanner, costing 160,000 “our wooden ones”, and he updates the firmware on it every year (about another $300 - $400) - the balalaika is not cheap. Here is a photo.
But as he says, all the latest changes and information on new car models appear immediately (not only GM, all cars from our TAZOVs to Infinity). Not one ELM 327 (from China) has such information, and certainly not! Who will “cover” the annual firmware? That's why many Chinese scanners have errors - CAN'T READ!
Diagnostics - he connected his “miracle device” and it showed that it was not a choke! Wow, a stone just fell from my soul, it revealed that it was a pedal! To hell with it, I’ll buy a new one for only 3,000 rubles, and replace it myself in a couple of minutes, unscrew one bolt, remove it and connect the cable.
However, the diagnostician told me - let's try to restore this one, if the error goes away then the pedal will be 100%, and then you will decide whether to buy a new one or drive on this one for a while. Okay, I agreed. But first he says - I’ll measure all the circuits - with a multimeter, I didn’t delve further, but it turned out that the pedal does not give any breaks! Unclear! It turns out she's whole?!
He tells me this - he recently came to see me in an Astra, code 84 + ESP was also on, in the end the contact on the ECU oxidized, they cleaned it, and everything worked like clockwork. Let's take a look at you. The 6 Volt load comes from there.
In the end, I didn't have to buy anything! The cost of repairs + diagnostics is 1500 rubles - SATISFIED AS AN ELEPHANT! The master noticed that the voltage at the ECU contacts is only about 3 - 5 Volts (there are a lot of them), therefore - YOU SHOULD NOT APPLY ANY LIQUIDS TO IMPROVE CONTACTS, such as terminal protection, etc. This way you can sag the voltage and simply burn out the ECU! You just need cleaning, it is advisable not to damage the protective coating of the contact (wipe with alcohol - carefully), then blow everything off with compressed air.
The moral of this story is that, after reading on the forum, I almost removed the throttle and disassembled it! Although it wasn’t worth doing this (specifically on my AVEO)!
GUYS FIRST, LET'S GO TO A DIAGNOSIS - A GOOD DIAGNOSIS! And then we’ll self-medicate (otherwise you might end up doing a lot of things). And yes, again, from the first steps, after adding antifreeze (if the level is gone), look at the contacts on the ECU, clean them - perhaps the problem will be solved. We rode with the master for about 5 - 10 kilometers, no mistakes!
This is the story, I hope it helped! I tried to put it on the shelves as much as possible, there is information on the Internet on forums, but it varies everywhere, there is no common denominator - maybe this, or maybe that! Check all the devices that I described to you - the error will go away in 95% of cases.
PS People for those who are looking for a diagnostician in Ulyanovsk - I’m writing my own, his name is Alexey, mobile - 8 (909) 3602112. Really, smart guy!

What is the reason for the errors?
There are a lot of reasons, but it’s worth noting that they are not always critical, so you shouldn’t buy spare parts right away!
Guys, I want to warn you - before sounding the alarm, you must first look for an intelligent diagnostician and only then draw conclusions! After all, my problem was not at all with the throttle. But this became clear later.
Precisely a smart one with a good scanner, who understands your Chevrolet or Opel, because if you connect a cheap scanner like ELM 327, then it simply may not detect the error!
SO, what problems there may be, I’ll start with, perhaps, the most harmless one:
Fuel pump and filter
Along with low-quality fuel, the fuel pump and filter suffer. Basically, the contamination of these elements leads to the fact that fuel does not flow in the required quantity, and this in turn leads to the appearance of a lean mixture, which can lead to high consumption or poor engine starting.
To eliminate the problem, you will have to replace the fuel filter. As for the gasoline pump, you will have to remove it from the car and replace the filter mesh, which is probably clogged. This procedure must be performed carefully, since you can accidentally damage the elements of the fuel pump.
Typical problems and malfunctions
All power units are quite reliable, without any serious flaws. Unfortunately, the same cannot be said for the manual transmission. The gear selection mechanism wears out relatively quickly. It is worth noting that, as a rule, it does not work perfectly even from the first kilometers. Ultimately, after 100,000 km, it may be necessary to replace the synchronizers. However, a lot depends on the operating conditions and regularity of maintenance. Mechanics strongly recommend changing the oil in the gearbox every 50,000 km.
On runaway cars, fogging is often observed in the area of the axle shaft seal at the exit of the gearbox.
At high mileage, there are failures of attachments: the air conditioning compressor (23,000 rubles), the starter (8,000 rubles) and the pump (a squealing noise appears from under the hood). Sometimes the ignition coils or one of the sensors (temperature or camshaft position) fail.
Problems also arise with the quality of the paintwork. The varnish is sensitive to scratches, and chrome surfaces lose their charm over time.
From a technical point of view, Aveo has a simple design, using solutions traditional for the B segment. MacPherson struts are installed at the front and a torsion beam at the rear. However, the simple device did not fully provide adequate durability. If there is practically nothing to break at the rear, then at the front the ball joints of the levers quickly exhaust their service life. Fortunately, the design provides for a replacement ball (from 500 rubles), which is secured with three bolts. It is also possible to replace silent blocks (about 500 rubles). But if all these elements are worn out, then you should think about installing a new lever (from 2,500 rubles).
The braking system uses disc brakes on the front axle and drum brakes on the rear. Drums, in principle, do not cause concern, unlike wheel bearings. The rear bearings come assembled with the hub (from 5,000 rubles), and the front bearings come separately (from 1,200 rubles).
The Chevrolet Aveo was affected by one serious service campaign, during which individual copies (in accordance with the specified VIN) required replacement of the ignition switch. Reason: the ability to independently start or stop the engine. Nothing like this has been recorded in Russia, but in the United States there have been several fatal accidents.
How are the codes deciphered?
As already noted, with each new car model, the number of codes increases. It is simply impossible to talk about all possible combinations in this article, so we will focus on some of them. There are a number of errors that occur most often, and some of them occur in extremely rare cases. It is advisable for car owners to print them out and take them with them in order to decide on the course of further actions at the right time.
An example is error P0300
, which reports multiple misfires. To get rid of this problem, you need to check the entire ignition system of the car. Control sensors are located in all major vehicle systems, so any malfunctions that arise do not go unnoticed.

Now that the main reasons have been identified - why the Chevrolet Aveo Check Light caught fire, you can move directly to methods for solving the issue. Of course, it is best to contact a car service to solve the problem, but many motorists, due to expensive repairs, try to solve the problem themselves.
So, before you start looking for a problem, you should connect to the electronic engine control unit and conduct a comprehensive diagnosis of all systems. To do this, you will need a laptop computer, a cable for connecting to the OBD 2 car and software that is suitable for this electronic control unit.
Having connected to the vehicle, it is necessary to carry out a comprehensive diagnosis of all systems, and then determine which errors have popped up and decipher them in order to determine the fault point. When everything is deciphered, you can proceed directly to troubleshooting.
Radiator fan does not turn on
After stopping the overheated engine, local overheating of the coolant begins at the points of its contact with the most heat-stressed engine parts and the formation of vapor locks. This phenomenon is called heat stroke.
Open the hood and inspect the engine compartment. Determine where the steam is coming from. When inspecting the engine, pay attention to the presence of coolant in the expansion tank, the integrity of the rubber hoses, radiator, and thermostat.
Never open the expansion tank cap immediately.

Problems with the Chevrolet Aveo t300 thermostat
Unfortunately, this is not the only problem with this thermostat. The same misfortune accompanies the owners of not only the Aveo, but also the Chevrolet Cruze and a number of other models with a similar Opel pedigree.
After 40 thousand mileage, the antifreeze distributor housing becomes completely unusable
Another problem is the plastic thermostat housing. Its quality and the quality of the rubber seals do not stand up to criticism. After 20-25 thousand runs, the thermostat housings begin to leak antifreeze from all possible cracks. Fighting leaks, as a rule, does not bring success, so the only correct solution in such a situation would be to replace the plastic case with a metal one.
Antifreeze leaks throughout the body
There are also questions about the thermostat valve. In its standard version it opens at a temperature of 104 °C and operates in a cyclic temperature range to a lower limit of 98 °C. In theory, the mechanical valve is installed as a backup device if the electrical part fails.
Standard Aveo T300 thermostat with antifreeze heater. Well, the code for ordering
However, many deliberately decide to buy a thermostat housing without a heater, saving themselves from problems with electronics in the future. A case such as the one shown in the photo is designed for this purpose.
This type of housing does not require the installation of a heater
And so that the electronic control unit does not become indignant due to the lack of a heater, a jumper is installed on the contact block. Electrical malfunctions occur when the radiator cooling fan is constantly on. In this mode of constant operation, it naturally does not last long - the bearings fall apart.
You can install a new fan, but it will suffer the same fate as the previous one if the problem is not radically solved. To prevent the Carlson from working in emergency mode, some changes are made to the firmware of the electronic control unit, which eliminates such problems forever. Yes, many still prefer to install a colder thermostat with an opening temperature of 92 °C on the Chevrolet Aveo t300. For example, Borg Wagner, which does not have a heater.
Metal distributor housing and thermostat housing without heater on engine
This is what we get if we install a thermostat without heating and edit the firmware:
- It is possible to update the firmware to the latest stock.
- There is no need to install a resistor in the heater connector; it is turned off by software.
- The radiator fan operates in normal mode, not in emergency mode.
- The cooling system works more efficiently and safely, which affects the dynamics, fuel consumption and engine life of the Aveo T300.

Chevrolet Aveo T300 Sensor replacement error 89
It is advised to immediately change this sensor without bothering with measuring the temperature of the engine and coolant. I read these two points in a comment somewhere on the Drive! Thank you kind man. But there may also be other problems that I hope neither I nor you will ever find out about... Like the car not starting, the thermostat housing leaking, and so on... After I realized that this problem is not a problem at all and the only thing that threatens me is the failure of the pipes, the breakdown of the fan, the complete leak of the thermostat, etc... I, as an experimenter of my car’s strength, decided to completely forget about this problem, here I ask you not to reproach me... Yes, that’s what I am!
