How is the VAZ 2114 cooling radiator replaced? This question interests many owners of cars of this model, which is a restyled version of the VAZ 2109. The hood and headlights have undergone changes, plastic moldings and spoilers have been installed, and a new VAZ radiator grille has been installed on the car.
Breakdowns happen to almost all cars, the consequences of which vary. If the radiator of a VAZ 2114 breaks down, the car’s engine may overheat and fail. Therefore, you need to regularly monitor and care for this very important device in the vehicle cooling system.
Reasons for removing a cooling system element
When a car breaks down, some reasons lead to the need to remove the radiator. The main ones:
- various types of mechanical damage;
- individual radiator tubes are clogged with dirt, deposits in the form of scale and rust;
- getting a car into an accident.
Replacing the device in question is not always required. Sometimes it can be repaired, washed, soldered. Modern radiators often have an aluminum core and a plastic tray. Such models are very difficult to repair.
To eliminate the malfunction or replace it, you will need to dismantle the device. You need to take this work very seriously and do it carefully. In order for the process to be carried out efficiently, you need to at least briefly know what parts the radiator assembly consists of. It includes:
- device body;
- expansion tank;
- Electrical engine;
- engine casing;
- impeller (fan);
- rubber cushion;
- drain plug;
- various hoses;
- a pump that is powered by a drive belt.
Cooling system: 1 – expansion tank plug; 2 – expansion tank; 3 – radiator supply hose; 4 – hose from the radiator to the expansion tank; 5 – radiator outlet hose; 6 – left radiator tank; 7 – aluminum radiator tubes; 8 – sensor for turning on the electric fan; 9 – right radiator tank; 10 – drain plug; 11 – radiator core; 12 – electric fan casing; 13 – electric fan impeller; 14 – electric motor; 15 – pump gear pulley; 16 – pump impeller; 17 – camshaft drive toothed belt; 18 – heater radiator outlet pipe; 19 – pump supply tube; 20 – hose for supplying fluid to the carburetor starter; 21 – carburetor heating block; 22 – exhaust pipe; 23 – heater supply pipe; 24 – hose for draining fluid from the carburetor heating unit; 25 – thermostat; 26 – hose from expansion tank to thermostat
Radiator replacement
is engaged in universal developments. For this reason, the VAZ 2114 radiator is suitable not only for this, but also for earlier and later car models. During the constant operation of this device, dirt may get into it and it may receive various mechanical damage. In some cases, the coolant itself can corrode some areas of the radiator from the inside.
How to remove the old one and install a new device? All work is carried out only on a cold engine, so as not to get burned by hot liquid. The VAZ radiator grille remains in place. Operating procedure:
- park the car on level ground;
- remove the battery;
- drain the coolant by unscrewing the special plug located at the bottom left of the radiator;
- remove the air filter;
- remove the protective screen;
- loosen the clamps and remove the upper and lower pipes, all tubes going to the expansion tank;
- disconnect the power supply wire and remove the fan;
- attach the fan system to the new unit;
- connect the fan power cable;
- lubricate the lower pipe with sealant and secure it in place;
- install the upper pipe;
- tighten the return clamp going to the expansion tank, secure the screen;
- install an air filter;
- fill the new radiator by pouring 5-8 liters of coolant into it through the expansion tank;
- start the engine and let it run for a few minutes.
Replace without removing the panel
But no matter what method is used, you will first have to drain the coolant from the system. Therefore, you will have to stock up on antifreeze in the required quantity in advance.
First, let's look at the replacement method without removing the panel. As already mentioned, this will require making cuts in some places.
To complete the work you will need:
- Set of screwdrivers of different lengths;
- Hacksaw blade for metal;
- Flat container for draining residual coolant from the radiator;
- Rags.
Having prepared everything and drained the coolant from the cooling system, you can begin work:
- We remove the storage box (glove compartment) from the panel, for which it is necessary to unscrew 6 screws securing it;
- Remove the side trims on the center console;
- Use a metal blade to make the necessary cuts: The first cut is vertical
, we do it on the inner wall of the panel near the center console (behind the metal strip of the glove compartment). Moreover, here you will have to make two cuts.
The second cut is horizontal
, runs in the upper part along the rear wall of the opening under the glove compartment.The third is also vertical
, but not end-to-end. It is done on the right on the rear wall of the lower storage shelf of the panel; - After all the cuts, part of the panel together with the wall can be bent down, which will provide access to the radiator. We bend this part and fix it;
- Unscrew the near bracket for fastening the heating system flap control cable and move the cable to the side;
- Loosen the clamps of the coolant supply pipes to the radiator. In this case, you should place a prepared container under the connection points, since liquid will flow out of the heat exchanger. Remove the pipes;
- We unscrew the three screws securing the radiator, remove it and immediately inspect it.
Some useful tips
Advice from professionals.
- To drain the coolant, you need to unscrew the plugs on the radiator, on the expansion tank and on the engine cylinder block.
- If the cooling system is not functioning well, the culprit may be a liquid cooling pump whose shaft bearings or seals have failed. It needs to be repaired or replaced with a new product.
- The cause of failure of the cooling system may be improper operation of the thermostat, which must be repaired or replaced.
- It is more convenient to remove the radiator together with the fan. The fan can be removed later if necessary.
You can check the tightness of the removed radiator as follows:
- fill the bathtub with water;
- lower the product into water and apply pressure of approximately 0.2 MPa;
- bubbles will show where leaks have appeared.
Sometimes, to bring the radiator into working condition, it is enough to rinse it with water. It's done like this. The antifreeze or antifreeze is drained and clean distilled water is poured in. The engine starts and runs at 3000 rpm. The temperature should be monitored. They turn off the car and after 7-8 minutes drain the water. If it is not completely clean, the procedure can be repeated. If the fluid has changed color, it needs to be replaced.
The coolant should be changed: antifreeze - after 2 years, antifreeze - after 5 years. The best choice for cooling fluid is antifreeze. The standard cooling system fan is quite noisy. Therefore, it makes sense to replace the original four-blade impeller with a new eight-blade one. When purchasing an impeller, you need to remember that the shaft for its attachment can have a landing thread of 8 mm and 6 mm.
Choosing a heater radiator for VAZ 2114, 2113, 2115
Which radiator to choose for the stove on a VAZ 2114? This question is gaining relevance in connection with the approaching winter. It's no secret that not all domestically produced cars have a good heater. Let's try to figure out which radiator to choose:
Copper radiator.
Immediately after purchase, the copper radiator has a heat output of 389.6 W/(m. deg).
The properties of copper are such that such a radiator takes a long time to heat up and takes a long time to cool down. The number of fins in a copper radiator is smaller than in an aluminum one, and the cross-section of the channels is smaller. Therefore, they clog faster and the stove blows cool air at idle. Most often, this is what VAZ owners complain about. The advantages of a copper heater radiator include its maintainability. This is where the advantages end. And the disadvantages begin: recently, manufacturers have been saving on raw materials and using impure copper. Some paint radiators to give them a marketable appearance, but this reduces the heat transfer of such a radiator. Lately it has been very difficult to find a high-quality copper radiator.
Aluminum radiator.
The heat output of the aluminum radiator is 209.3 W/(m deg).
This radiator heats up quickly and cools down quickly. The number of fins in an aluminum radiator is much greater than in a copper one, which is a definite plus. The cross-section of channels in an aluminum radiator is also larger than that of a copper radiator. Thanks to this, they do not clog longer and have greater heat transfer.
The disadvantages of an aluminum radiator include its non-repairability in case of leakage.
So which radiator should you buy?
Just a few years ago, the answer to this question would have been: copper. But time passes and today it is difficult to find a high-quality copper radiator. Therefore, our choice at the moment: aluminum.
However, we do not recommend buying painted radiators, because... their heat transfer is lower and an unpleasant odor may appear in the cabin.
Of the companies, we do not recommend buying heater radiators manufactured by Luzar. There are too many negative reviews about them.
How to prepare the VAZ 2114-15-13 stove for winter.
In order to avoid problems with the interior heater in winter, we recommend doing the following:
- Replace the coolant and flush the entire cooling system.
- Replace the interior heater radiator with a new one.
- Replace the engine cooling radiator with a new one
- Change the pump.
- Remove air from the cooling system.
These steps will help you avoid heat problems in the winter. Replacing radiators will help avoid contamination of the coolant, and replacing the pump will guarantee its normal circulation in the system.
