Print this article Font size 16

In fact, the cooling system pipes on a VAZ 2110 car cannot be called strong, reliable and durable elements. Over time, they can wear out and lose their effectiveness. Therefore, the only thing left for the car owner is to replace them.

Rubber tubes for CO

Today we will tell you how to remove and replace these elements. You must act strictly in accordance with the operating instructions and observe all safety precautions. This will allow you to protect yourself and your car from unnecessary troubles.

Replacing the cooling system pipes of a VAZ 2110

Rubber tubes for CO

Preparation

Silicone
Removal of pipes is necessary only when the car engine has completely cooled down. Therefore, if you have just stopped by your garage for procedures, do not rush. It is better to leave the car overnight and return to work tomorrow morning.

Make sure that the pipes are actually damaged and need to be replaced.
Be sure to drain the coolant from the system. If you recently changed it, there is no need to dispose of the liquid. Just use a clean container to drain so you can refill it later.
The order in which you perform the work depends on what hoses are used on your vehicle.

Leak search

Finding out the reason for this state of affairs is not always easy. To do this, the driver will have to carefully examine the situation under the hood. Usually you can only notice a wet pan. In this case, it is worth checking the coolant level in the system. Most likely, there has clearly been a decline.

The cause and location of the leak is not easy to recognize. It is useful to “drive” the car at idle for some time so that the thermostat opens. And only when the optimal pressure is reached will the source of the leaks reveal itself. Most likely, one of the connections of the pipes is leaking, often it can be the pipes for supplying antifreeze to the heater radiator; if this is the case, we proceed to replacement.

Standard pipes with union connector

Standard
If such hoses are present, dismantling them is carried out as follows:

Elements of this type are usually mounted using clamps. Just check what kind of clamps they are - disposable twist type or standard worm clamps. If they are disposable, we highly recommend replacing them with worm driven items. They are more practical and reliable;
Armed with a screwdriver, loosen the clamp slightly and move it along the pipe. This way you can completely release the fitting;
The hose is carefully, without unnecessary or sudden movements, removed from the receiver, that is, the fitting. Quite new pipes that have not yet worn out are easy to remove, but old ones can “stick”;
If the element does not want to be removed just like that, twist it on the receiver, pry it with some sharp object, and pull it. You just can’t put in a lot of effort, because the pipes are very fragile. If the situation is really sad, just cut the hose with a knife. It is simpler, easier, although it will require large financial costs;
When installing new hoses, clamps are first put on and then pulled onto the cooling system receivers;
If you previously used a twist-type clamp, be sure to remove it. As an alternative, both a screw clamp and a worm clamp are suitable. There is no big difference in price, but the level of reliability is significantly higher;
If you have difficulty fitting the elastic pipe onto the fitting, slightly wet the latter with soapy water. Another option is to warm the ends of the hoses in warm water;
To facilitate installation, never use lubricants containing oils;
Pull the ends of the hoses onto the fitting, check the correct installation and laying in the engine compartment;
Now move the clamp to the required position and tighten, thereby ensuring a strong fastening of the new element of the cooling system;
Follow the procedure to fill the system with coolant;
Turn on the power unit and watch for signs of coolant leakage. It is quite possible that the clamp was not tensioned tightly enough, or there is a defect on the pipe itself. Although such things should be checked before purchasing.

Why do you need a pump in a car?

If we talk about the operation of a car engine, then we immediately touch upon the topic of its cooling. Indeed, without high-quality cooling, the engine will not be able to work for a long time and will definitely “boil”. Thanks to the circulation of coolant, it becomes possible to operate the engine at any time of the year under any external conditions.

The power component on the VAZ of the tenth family has a rather complex structure. During the working cycle, the pistons rub strongly against each other, which invariably leads to strong heating of the surfaces. The only way to prevent engine overheating is to constantly maintain the desired temperature in the friction zone through the circulation of coolant. It is for this purpose that the VAZ design includes a cooling system.

Coolant (antifreeze or antifreeze) is poured by the driver into the expansion tank of the car. From it, the liquid is transferred through pipes to the water pump, and from there it goes to the radiator and cylinder block. The water pump (or pump) is designed to pump antifreeze through the system while the engine is running. That is, the pump starts together with the engine and turns off after the driver turns off the car. Without a pump, the entire cooling system can be considered ineffective, since only the pump can create rapid circulation of liquid throughout all parts of the system.

The pump is designed to create the necessary pressure in the cooling system to move the liquid.

Heater heat exchanger hoses

The other hoses in the VAZ 2110 cooling system are those connected to the heat exchanger of the heater.

Hose diagram

, the O-rings must be replaced . Therefore, we advise you to purchase them in advance. The dismantling procedure itself is as follows.

Two heater hoses are connected to the heat exchanger using a single connector. Some modifications of the VAZ 2110 may require dismantling the camshaft cover.
Remove the metal clip that is located on top of the connector.
Push the plastic tab towards the left side of the connector to release it.
Remove the heat exchanger connector, remove the old O-rings. It is strongly not recommended to return the same ones to their place.
An alternative to such connectors can be hoses with a spring clamp made of metal.

Dismantling and installation

To remove the cooling radiator from a VAZ 2110 with your own hands, you must:

Drain the coolant through the bottom plug;
Remove the battery as it is in the way;
On the injection VAZ 2110, it is also necessary to remove the air filter;
The upper mount to the frame must be disassembled, simultaneously releasing the fan;
Remove the electric fan;
Remove two hoses - for steam supply/discharge;
Tilt the radiator towards the engine and remove.

That is, removal is quite simple. Now, if the radiator leaks slightly, but is not severely damaged by corrosion, you can repair it. Otherwise, replace it. When choosing a new radiator for a VAZ 2110, be sure to take into account the model of the previously installed one so that the new one fits perfectly.

When installing, make sure that the rubber pads on which the body rests with the lower part fit firmly into the holes on the cross member.

Next, you need to fill in the coolant (you can use the old one by filtering it), and then start the engine.

Replacement

Replacement
Now all that remains is to install a new set of pipes and complete this job. For this:

Carry out installation by following the reverse sequence of disassembly and dismantling;
Be sure to put new O-rings in place;
Fill the cooling system with coolant;
Start the engine and make sure there are no coolant leaks.

As you can see, replacing the cooling system pipes can easily be done with your own hands. This will require accuracy, consistency of your actions, as well as the use of new, high-quality parts to replace the old ones.

If you cannot or do not want to deal with such issues yourself, contact a good car service center, where they can quickly and efficiently bring your cooling system to normal condition.

Features of draining antifreeze and replacing the pump pipe on a Priora

The coolant pipe on the Priora is connected through a hose to the thermostat. It regulates the circulation of antifreeze in a small or large circle, depending on its temperature. If a defect is detected on the pipe itself or at the junction with the pump and the unit, it must be dismantled. The procedure involves preliminary draining of antifreeze.

The work is performed in the following order:

The engine protection is removed;
The expansion tank cap opens;
Carefully unscrew the “lamb” of the drain located at the bottom of the block;
Antifreeze is poured into the prepared container.

Drain hole on Priora

Draining is performed on a cold engine. To completely drain the coolant, you need to turn the motor shaft using the starter.

The supply pipe is dismantled after unscrewing the 2 mounting bolts on the cooling pump and removing the thermostat hose. The new part and gasket are installed in the reverse order. After adding antifreeze, it is necessary to test run the engine and check for fluid leaks at the connections.

Lada 2110 PhiX › Logbook › Replacing the upper pipe of the VAZ 2110 cooling system

Hi all! Unexpectedly, a small problem occurred: the upper pipe of the cooling system ruptured. About 4 liters of antifreeze leaked out, which is approximately half of the total volume.

The breakdown, although unexpected, was quite predictable. The car is already 12 years old, and naturally, no one has changed the pipes over the years. During extreme maintenance of the cooling system, www.drive2.ru/l/5156633/. which was only half a year ago, the thought of replacing the pipes came to my mind, but the “toad” defeated common sense. The end result is a waste of time and money.

New pipe CO 220r,

5l Antifreeze “Felix” 680 RUR,

Clamps “Norma” 2 pcs. 90 rub.

Fortunately, the store was still open; it was about 20:00. I had to change the pipe on a hot engine, right in the parking lot in front of the store, what a pleasure.

The pipe broke for a reason; it probably happened during sudden braking, which had to be done so as not to roll over a pedestrian who was crossing the road in the wrong place. The engine bit on the cushions and pulled the pipe, which had already lost its elasticity. Change the pipes in a timely manner and save time and money.

Replacing the pump and pump supply pipe — Lada 2109, 1.5 l., 1999 on DRIVE2

Not even after 20 thousand the pump started leaking. I also noticed that antifreeze was leaking at the junction of the pump supply pipe and the block. For those who don’t know, it is located at the rear of the block, in the most inconvenient place in the front-wheel drive family.

At first the pump did not flow much, then a river appeared.

I chose the time and started replacing. I carefully drained the antifreeze and had to come up with a whole system. It was not difficult to remove everything. When I removed the carburetor heating hose, I saw that it was all cracked and dry. It's strange that it hasn't leaked yet.

The oil seal on the pump leaked and a creaking sound appeared when rotating. The gasket on the supply pipe is rotten. In principle, I could have left the old pipe, but I immediately stocked up on a new one.

I bought the pump from Mstart. To be honest, I have never heard of this, but the seller assured me that it was good. I immediately took a roller of some kind, a Continental Contitech belt, I had heard a lot about its quality.

in the photo above, the Finwhale belt is on top - 23 thousand km, in the middle Goodyear - it's unknown how long, but more than 15 thousand km, on the bottom is a new Contitech

I cleaned the seats of old gaskets and spent a long time fiddling with the seat pipes. It was very inconvenient, I had to jack up the car and clean it while lying under it. I wiped off the old traces of antifreeze a little to suddenly see a new leak.

While I was taking pictures of the whole thing, in the light of the flash I saw fogging on the intake manifold. You'll have to change the gasket.

The new pipe laying was sealed with sealant. It is extremely inconvenient to put it in place. While baiting, I reapplied the sealant 2 more times: it had time to dry, and rubbed a callus on my finger. Tightening is also inconvenient; you can’t get anything in there except a spanner.

I assembled everything, installed it, tightened it. Replaced the carburetor heating hose. Filled with antifreeze. Everything is fine. Everything is working.

After that I drove another 1000 km. Everything is dry, you can only see that the belt has eaten a little. Now I'm wondering why he's slipping. Most likely the pump is crooked. We'll watch.

Well, according to tradition - smooth roads to everyone))

VAZ 2110: replacing the stove pipe yourself

Removing the stove pipes for heating the interior

To maintain the desired temperature inside the VAZ 2110 car, there is a device called a heater or stove. The automatic control system allows you to adjust the temperature with an accuracy of two degrees. On a VAZ 2110, the stove in which the pipes can fail can fail.

Introduction

Replacing a VAZ-2110 stove is a very important and responsible undertaking that will require more than one hour of free time. It is especially important to prepare the heating unit for the upcoming frosts, because a functional stove will be able to provide comfortable movement for all passengers and the driver. As a rule, replacing the VAZ-2110 heater is necessary due to a faulty radiator. True, the malfunction may be hidden in the presence of smudges of antifreeze or antifreeze oozing from the radiator (the pipes have expanded).

Pipes in the heating system of VAZ 2110

Any car that has liquid in its heating system uses all kinds of pipes to connect all the elements. When operating a VAZ 2110 car, they need to be given special attention. If the defect that appears is not corrected in time and the pipes on the VAZ 2110 stove are not replaced, this can lead to problems with the car’s engine. Attention must be paid not only to them, but also to the clamps that ensure a tight connection. A loose clamp or not tightened in time can lead to unexpected engine overhauls.

Required parts for repair

The kit to replace the VAZ 2110 heater pipes includes four hoses

The photo shows a set of pipes:

lower pipe for draining fluid from the radiator;
upper inlet pipe;
shorts of the water pump and thermostat couplings.

The upper inlet pipe supplies heated fluid to the radiator, and the lower outlet pipe removes cooled engine fluid from the radiator. If leaks are detected from the pipes, it is necessary to urgently replace these elements on the VAZ 2110.

Replacing Thermostat VAZ 2112 16 Valves

Replacing the thermostat on VAZ 2110, VAZ 2111, VAZ 2112

Thanks to the thermostat, the engine can heat up very quickly, and also not actually heat up at all, all this happens for the following reasons, in the thermostat itself there is a so-called valve, this valve is filled with a special substance with the help of which the thermostat determines when it needs to open one hundred percent and when it needs to be locked one hundred percent, we all already know that when the engine is running (Maybe we paid attention), the car heats up very quickly to about 80 degrees, and after 80 degrees the engine heats up a little less, and after 94 c° it actually doesn’t heat up at all unless you are stuck in a traffic jam for many hours, the whole point is that the thermostat valve releases coolant into a large circle when it reaches 80 c°, and after 94 c° the liquid goes out to the same circle but only the circulation of water in a small circle stops altogether and as a result the car heats up less.

In order to change the thermostat to a new one, you will need to stock up on: A screwdriver and one hexagon of approximately “5”!

It is located a little lower than the air filter housing, it is not at all difficult to see it; to do this, open the hood of your car , then look for this same air filter housing in the engine compartment and after finding it, look a little lower, so to speak, under it, and that thermostat will be installed there (More precisely its lid, and this unit itself is located inside the lid), for example, the location of the lid is also shown in the photo just below:

When should you change the thermostat?

It is replaced only in this case if he did not open the valve that releases coolant to a large circle, and also if he left the valve in the open position and this valve is jammed.

In the first case, if the thermostat does not release liquid in a large circle, then the car will begin to heat up very much, under no circumstances allow it to overheat and, if possible, change the thermostat recently, especially if your car’s engine operates at elevated temperatures, then your cylinder head gasket will gradually burn out, and the friction in your car’s engine will also increase, since as we all know from the law of physics, the higher the temperature, then the metal expands accordingly, and the larger the metal becomes, the larger it becomes its friction, so watch the engine overheating very closely.

In the second case, if your valve gets stuck in the open position, although this happens occasionally, you still decide for yourself whether you need to replace the thermostat or not, since if the valve is in the open position, then the engine will actually will not heat up, but if it’s winter outside, it would still be better to replace this unit with a new one!

A channel on the topic of cars, worthy of attention and useful.

How to check whether the thermostat is working or not?

Work order

Every slave must have its own consistency. Then it can be done efficiently.

The wire from “—” is disconnected from the battery.
The coolant is drained.

Tip: Before draining the coolant, you must allow the engine to cool, otherwise the temperature of the drained liquid will be high.

The lining, frame trim on the windshield, and sound insulation upholstery are removed.
The heater fan is removed.
The vacuum hose clamp is disconnected from the stove body.
Using a screwdriver, remove the three spring clips that secure the front housing of the heater air collector.
Remove the screws securing the front housing.
The front housing is removed.
The tightening of the clamps is loosened and the hoses are disconnected from the fittings.

Installation of new pipes

When replacing the stove pipes on a VAZ 2110, it is better to replace the clamps connecting all the elements. So:

Replacement in progress. New pipes have been installed on the VAZ 2110 stove for supplying coolant and draining it from the radiator.
The remaining parts and assemblies are installed in the reverse order.
Coolant is poured into the cooling system and the tightness of the pipes and all connections is checked, if necessary they are tightened.

Replacing a tee or outlet hose of a VAZ 2110 heater radiator

Attention: There are cases when coolant leaks at the junction of the tee with the heater, expansion tank and engine cooling pump.

Sometimes it is enough just to tighten the hoses on the pipes with new clamps.

Tip: Tightening the clamps must be done very carefully so as not to cut through the rubber of the hose, which may lead to the replacement of the hose.

Repairing a hose without removing it from the car

The damaged end of the element is cut off.
A piece of the same hose is attached to a metal pipe approximately 60 millimeters long and 20 millimeters in diameter. The price of such an element is low, which saves money and repair time.
To reduce the tension of the hose, its length should be increased by 8 millimeters.
If antifreeze leaks from the joint between the hose and the heater radiator, then it is necessary to remove the vacuum booster.

How to replace the stove pipe of a VAZ 2110 is clearly visible in the video presented.

Replacing tee hoses

Instructions and work order:

The clamp securing the filling hose to the tee branch pipe is loosened.
Coolant is drained from the expansion tank.
The clamp connecting the hose of the tee and the branch pipe of the pump supply pipe is loosened, the hose is removed from the branch pipe, and the remaining liquid is drained from it.
The rubber belt securing it is unfastened from the expansion bull.
The connector is removed from the sensor that monitors the level of cooling liquid in the tank.
The hose that removes steam from the tank is disconnected.
The tank is removed from the niche and moved to the side, along with the second hose that removes steam.
Unscrew the screws securing the left noise-insulating upholstery of the engine compartment.

The top screw holding the central upholstery is removed.
Remove the connector from the sensor in the brake reservoir, which monitors the fluid level in it.
Unscrew the nuts securing the vacuum booster of the main brake cylinder.
The cylinder is removed from the studs and, together with the brake pipes, is moved forward. This causes the tubes to bend.
The hose is removed from the vacuum booster pipe, having first bent the upper corner of the upholstery.

Further work is performed inside the car:

We move the vacuum booster, bracket and brake pedal assembly to the side and free access to the pipes located on the heater radiator.
To disconnect the lower hose, you must first remove the upper supply hose.
The clamp is loosened and the lower hose is removed from the pipe.

Installation of new elements is carried out in reverse order.

Tip: For greater reliability of the connection, before installing the tee on the pipes, it is better to install additional clamps.

A timely inspection and, if necessary, replacement of the hoses of the VAZ 2110 stove and the car’s cooling system, with your own hands, is the key to reliable operation of the car’s engine.

Replacing the pipe

I went to the store, bought a set of pipes (in reserve), clamps, and antifreeze to top up. I returned to the garage and began to disassemble. This was my first time replacing this pipe. I knew that it was going to the stove and I also knew that I would have to take a lot of disassembly, plus drain the antifreeze.

First things first. First, I unscrewed several screws and removed the left trim (aka sound insulation). Then I removed the air pipe, loosening two clamps, and also disconnecting the crankcase ventilation pipe.

Next, I proceeded to dismantle the front window trim and removed the wiper arms.

After all the operations performed, I finally saw where the damaged pipe ends. But it is blocked by the heater fan housing.

So we’ll remove it too. It is held on by three screws and two top latches. There were no problems with withdrawal. In one step I cleaned the fan of debris.

I didn’t take out the fan itself, I just moved it a little to the left. And now I had access to the clamp and pipe.

Replacing the supply pipe from the pump to ICE 2111, VAZ 21102 — DRIVE2

Hello everyone. I'm going to change the saxophone on my TORPEDO. I purchased the saxophone itself, everything else is mine. First you need a gasket to install the pipe to the pump. To make it you need: paper cardboard, a pen, scissors, a razor blade, and the saxophone itself.

Repair for removing the pipe: 1 pull out the armored wire from the 4th spark plug to easily unscrew the ignition module. 2 unscrew the clamps on the air filter pipe with the mass air flow sensor, the throttle and on the valve cover. 3 pull out the pipe with the filter and mass air flow sensor. 4 unscrew the ignition module. 5 drain the coolant into container.6 unscrew the clamps on the pipes in the pipe.7 pull the pipes out of the pipe.8 unscrew the nuts securing the pipe from the pump.

9 pull out the pipe from the battery side.

Repair for installing a pipe: 1 smeared the pre-cut gasket on both sides not with sealant but with solid oil. 2 stuck it to the place where it should stand on the pipe. 3 push the pipe to the installation site. 4 jacked up the right front part with a rolling jack. 5 drive up the car. 6 I put a bolt with a regular washer + a lock washer into the lower part of the pipe mount. 7 I baited it, screwed it halfway. 8 I put a bolt with a regular washer + a lock washer into the upper part of the pipe mount. 9 I baited it, and screwed it halfway.

10 Then I tightened everything with a wrench on the right side.

Repair to check what has been done: Tighten the plug on the side of the ignition module, Tighten the ignition module itself, Put the pipes on the supplied pipe, Tighten the clamps, Put the air filter pipe with the mass flow sensor in place, Tighten the clamps, Fill in the missing coolant, Start the engine, Warm it up, Look at the bottom the presence of a leak, Smile at the work done, Be proud of the hands from the right place and that you did it yourself and did not give money to a service center, And drive with confidence in your car until the next repair. All. Not a nail, not a rod.

How to drain antifreeze

Now all that remains is to drain the antifreeze into a container. I used a 5L bottle and only drained from the block. See how to drain antifreeze here.

A piece of garden hose (about 1.5m) worked very well for draining.

That's all. After draining the coolant, I unscrewed the two clamps of the torn pipe and replaced it with a new one. That's where the pipe broke.

I didn’t encounter any particular difficulties in my work, even though I was doing it for the first time. As a result, I gained invaluable experience and money savings. The service would charge from 600 to 800 rubles. In addition, I wiped all the hidden cavities and removed debris from them. It's unlikely that a service station would do this to you.

Why is the lower radiator hose cold? List of possible problems and how to fix them

Or they go to the store and buy a new radiator;
Or you can clean it yourself.

The radiator must be cleaned when the engine has completely cooled down;
It is recommended to wear protective gloves and firmly fasten the car hood;
All coolant is drained from the radiator and checked. If the liquid is perfectly clean and there are no traces of rust or scale in it, the radiator is clean and the reason for the cold pipe is different;
If the liquid is dirty, then that's it. Pour clean water (necessarily distilled) inside. We start the engine and let it run for 20 minutes.
We drain the water, check for cleanliness and, if necessary, repeat the procedure several times.

Causes of poor coolant circulation

According to the above diagram, the reason that the lower radiator pipe in the VAZ 2110, 2114, 2115 remains cold is the lack of fluid circulation in a large circle of the system. Note that the radiator is the main cooling element. Therefore, the upper pipe through which the liquid enters the heat exchanger will be hotter than the lower one, even if the liquid circulates correctly.

Possible causes of stagnation in the cooling system:

radiator clogged;
non-working thermostat;
airlock;
pump breakdown.

Any intervention in the engine cooling system requires subsequent flushing of the ODS and replacement of the coolant. Poor quality coolant cannot cope with cooling the engine and can cause a blockage in the system.

How does CO work?

CO scheme

On the 8-valve injection VAZ 2110, the cooling system operates due to coolant forcedly circulating through it. When the engine heats up, excess pressure arises, which is released through the exhaust valve.
For the 16 valve injection VAZ 2110, the cooling system has an optimal operating temperature in the range of 90-95 degrees Celsius. And the valve is activated when pressure occurs with indicators from 1.2 to 1.4 kgf/cm2.
When the excess pressure is released, the engine returns to normal temperature and the intake valve is turned on. This happens cycle after cycle.
If the pressure balance is disturbed, overheating occurs, the consequences of which can be various types of breakdowns, including the need to completely replace the power unit.
Due to the operation of the thermostat and electric fan, the VAZ 2110 maintains the required constant operating temperature. There is a sensor on the cylinder head that transmits information about the current coolant temperature to the control unit.
A command is sent from the coolant temperature sensor to the cooling system, which begins to work in order to reduce engine heating.
If there is electronic injection in the car design, it also has a special sensor that sends a message to the electronic control unit about overheating of the power unit.
The pump supplies coolant, distributed by the thermostat.
When you turn on the engine, it needs to warm up to operating temperature. To do this, the thermostat directs the coolant through a small circuit, without including circulation through the radiator. The small circuit includes: Heater for warming up the interior;
Carburetor heating unit (naturally, only on carburetor VAZ 2110);
Heating of the throttle unit;
Intake manifold.

When the engine warms up to approximately 90 degrees Celsius, the thermostat sends some of the coolant to the radiator.
When the engine overheating sensor is triggered, all the cooling liquid circulates through a large circuit. Article on the topic: Fuse for the cigarette lighter VAZ 2114
