Correct replacement of the cooling radiator on a VAZ 2114

Required spare parts

First of all, you need to select a new radiator. It is better to purchase an analogue of what is on your car. You can also make a choice by article number: 2108-1301012, 21082-1301012, RO2108-01, LRc 01082.

The average price of a new unit is 1,750 rubles. Copper models will cost more.

Attention ! It is better not to purchase painted radiators, since there is a risk of an unpleasant odor appearing in the interior, and the heat transfer of these models is lower.

Tools required for repairs

If you want to do the repairs yourself, you need to prepare the following tools:

keys for 8 and 10;
screwdrivers;
heads for 8 and 10;
pliers;
container for draining antifreeze;
jack;
sealant;
rags.

Independent work is completely justified, since as of March 24, 2019, the average price for replacing a cooling radiator for a VAZ 2114 and other models is 2.2 thousand rubles. Which will more than double costs.

On a note! It is not difficult to monitor the efficiency of the radiator and reduce the risk of engine overheating. It is necessary to regularly check the volume of coolant in the tank and the operation of the thermostat.

The main causes of radiator failure

Engine cooling radiator

Let's look at the main reasons for radiator failure on a VAZ-2114:

mechanical damage (bounced stones or large debris on the road);
deposits inside the tubes in the form of scale or rust, dirt;
damage as a result of an accident.

How to prevent engine overheating?

To prevent engine overheating, it is necessary to constantly monitor the amount of coolant in the expansion tank, the operation of the thermostat and the condition of the radiator itself.

This is what a newly installed engine cooling radiator looks like. You need to make sure it is clean and blow it out regularly.

The appearance of traces of coolant on the asphalt after a short or long period of parking, as well as wet marks on the radiator itself, is a signal to check the radiator for leaks and possibly subsequently replace it.

Coolant leaks can be caused by small cracks or loose connections. In such cases, it is possible to repair the radiator even without dismantling it. When repair is not possible, the only option is replacement.

Order of Operations

If the car has a low seating position or the coolant drain tank is large, work should begin by lifting the car with a jack. The radiator is installed on the TV along with fog and regular headlights. Work should only begin with a cold engine. If the engine is hot, be sure to wait until it cools down.

On a note! Mandatory conditions for performing operations are strict adherence to the sequence and extreme accuracy. Because the engine cooling system is one of the main ones in a vehicle. In parallel with the replacement, it is advisable to revise it and make sure that other components are in good working order and are working properly. Now you can get started:

After removing the plug from the expansion barrel, the working fluid is drained into a container. It is necessary to drain all the antifreeze that is in the cooling system.
Now you need to dismantle the filter.
The radiator must be removed together with the electric fan. To do this, you need to disconnect the power supply to the cooler. Now you need to unscrew the pressure plate and remove it.

Now you need to remove the inlet and outlet hoses from the pipes. To do this, loosen the fastener clamp.
The radiator with fan is tilted towards the engine and removed. Attention! Before pulling out the fan, you need to disconnect the wires. They are usually located at the bottom of the device. This is necessary in order to maintain the functionality of the wiring.
Now you need to disconnect the fan from the radiator. To do this, use a 10mm wrench to unscrew 2 nuts. The fan must be removed along with the casing.
Installation of the radiator is carried out in the reverse order to that described above. It begins with switching the new node and the fan. Important! Before replacing, make sure that there are 2 rubber cushions. If they are missing, install new ones in the crossmember holes. If they are in place, then the installation of the new unit is carried out on them. The main causes of radiator malfunction

The most common reasons for radiator failure on VAZ 2113, 2114, 2115 are:

mechanical shocks, for example, stones bouncing off the wheels of passing vehicles;
pockets of corrosion and contamination inside the tubes;
damage in an accident.

How to change the radiator on a VAZ 2115

Radiator VAZ 2115

Engine overheating is a terrible phenomenon that promises its owner major repairs and serious cash injections. In order to prevent engine overheating, it is necessary to regularly monitor the coolant level, proper operation of the thermostat, and the condition of the engine cooling radiator.

If you find a coolant leak or puddles after a long period of parking, check the engine radiator for coolant leaks. A wet mark or hole in the radiator is a signal for immediate action. If the crack or breakdown is small, you can try to solder the cooling radiator. In addition to cracks and holes in the radiator, leaks can be caused by faulty connections or loose clamps. If the reason is not the clamps, and repairing the radiator is impossible or unprofitable, the radiator will need to be replaced.

How to remove

1) First, drain all the liquid from the cooling system (How to drain the liquid, read the article: “Replacing the coolant on a VAZ”), when the coolant is drained, remove the air filter housing so that it does not interfere (How to remove the housing, read “in this article") and after the completed operations, you can begin to unscrew all the bolts that secure the fan to the radiator (Without unscrewing them, you will not remove the radiator), but just do not forget to also disconnect the pipes before unscrewing, they are fastened with screws, there are only three pipes that fit radiator (Two large, one small), when they are already disconnected, you can begin to unscrew the bolts and nuts securing the fan, there are only two such bolts, but in addition to the bolts, the fan is also held in place by nuts (And there are only four nuts), one nut is located in the the lower part of the fan on the side (It is easy to see if you remove the crankcase protection and crawl under the bottom of the car) and the other three are at the top (see small photo, they are indicated by arrows) and two of these three nuts also hold the pressure plate (Indicated by red arrows ), so when the nuts are unscrewed, remove this plate and put it away, but just be careful not to lose it, otherwise in this case you will have to go to the auto shop for a new one, and when all four remaining nuts are unscrewed, remove the fan by tilting it towards the engine and pulling it out up (On 16-valve cars, you can’t remove it to the top, because the engine will get in the way, so both the radiator and the fan are removed through the bottom).

Let's summarize

In general, repairs are quite accessible for doing it yourself, but you need to immediately prepare for a significant time investment. Work can last for 2-6 hours. When replacing the radiator, it is necessary to change the coolant. Work with 8-valve and 16-valve engines is carried out in the same way. If the car has air conditioning, you will have to remove and install it during the repair, but not on all models. It is advisable to replace the bushings at the same time. The work is completed by checking the functionality of the engine and the condition of the coolant. Namely, whether it is boiling.

Replacing the cooling radiator for a VAZ 2114

VAZ 2114 is considered one of the most striking examples of success of the domestic automobile industry. This model is a modified version of the VAZ 2109 and differs from it in the design of the front part of the body, updated headlights and hood, radiator grille design, as well as plastic moldings and spoilers. However, as it became known, the car is susceptible to radiator failures, which can lead to overheating, and as a result, to engine failure.

Replacing the cooling radiator

It is worth noting that the radiator from 2114 is also suitable for other representatives of the VAZ model range. As you know, VAZ’s developments are universal, so it is not surprising that not only cooling system parts, but also other spare parts from earlier and later models of this brand will ideally fit the 2114.

As one of the main parts of the cooling system that is in constant operation, the radiator may require replacement because it becomes clogged with debris or suffers mechanical damage. In addition, the coolant must be replaced in a timely manner, otherwise it will corrode it from the inside, which will undoubtedly lead to breakdown.

How to remove the old one?

Dismantling the cooling radiator and its pipes VAZ 2114

Before a replacement is made, regardless of the vehicle manufacturer, it is worth remembering that the process of dismantling the old and installing a new radiator must be carried out on a cold engine, and the VAZ 2114 is no exception. In addition, before replacing this spare part, you must disconnect the battery and drain the coolant by unscrewing the plug located at the bottom left.

To avoid burns, be sure to cool the engine before draining coolant.

After draining the cooling liquid, you need to remove the air filter secured with two bolts, freeing the air duct filter by loosening the clamp.
After the radiator is freed from the air filter, it is necessary to dismantle the protective screen provided by the VAZ developers. To do this, you need to loosen the upper fastenings, remove the iron clamp and loosen the return clamp of the expansion tank.
You should also remove the pipes: the upper one can be dismantled by loosening the iron clamps using a 8-mm wrench or a screwdriver, while the lower one, in most cases, is not only screwed to the thermostat, but also sealed with a special sealant that prevents fluid from leaking from the radiator. To remove the lower pipe, you need to remove the sealant and loosen the clamp.
In addition, it is necessary to disconnect the fan power cord, after which the part itself can be removed by removing the landing pads.
Removing the radiator and its fastenings
Then you need to remove the fan, screwed on with several nuts. The main work of dismantling the main part of the engine cooling system has been completed, the only thing left to do is replace it.

How to secure a new one

Connect the fans to the new cooling system and tighten them with nuts.
After this, carefully insert it into place, putting the landing pads on it, and connect the power plug to the fan.
Then you need to secure the lower pipe to the thermostat, generously lubricating it with sealant to prevent leakage, and also secure the upper one and tighten the clamps.
Next, you need to fix the expansion tank return clamp, attach the screen and secure the iron clamp.
After this, you should install the air duct and air filter, also securing it with a clamp.

Algorithm for replacing the VAZ 2115 radiator

If the engine overheats severely, major repairs and large cash injections will be required. To prevent this, you need to monitor the coolant level, proper operation of the thermostat, and the condition of the engine cooling radiator.

Wet marks or a hole in the radiator, a coolant leak or fluid accumulation during long-term parking require immediate repair of the engine radiator. You can try soldering the radiator if the crack is small. In addition to cracks and holes, poor connections and loose clamps can lead to leaks. If this is not the case, and repairs are not financially viable, you will need to replace the radiator .

Worth checking out:

You can replace the radiator at a service station or yourself.

Refilling a new radiator

Coolant refill

Finally, “Tosol” or antifreeze should be poured into the expansion tank of the new radiator. Basically, approximately 5-8 liters of liquid are poured into the new cooling system to cool the engine. After filling with antifreeze, the car must be started and left running for a few minutes so that the thermostat opens and the antifreeze goes into the engine cooling system. Replacing the 2114 radiator, like any other VAZ model, should be carried out in a warm room or in the summer season.

How to properly replace a radiator

Before replacing the radiator in their car, many car owners ask the question: “how to remove the cooling radiator?” In this article you will find answers to your questions.

How to remove the radiator?

Radiator and fan parts:

Radiator.
Radiator tank.

Electric motor.
Casing.
Impeller.
Rubber cushion.
Drain plug.

So, before starting work, you should remember that the entire removal and installation process takes place on a cold engine.

First of all, we unscrew the cap of the expansion tank (do not forget about the radiator and cylinder block caps - they also need to be removed).
Drain the coolant into a clean container.
Disconnect the radiator fan from the power supply.
We disconnect all the hoses, both from the radiator and the expansion tank.
Then we proceed to unscrewing the nuts from the cooling system casing.
Hold the radiator and remove the casing with the fan.
The radiator is free and ready to be removed.

If necessary, you can also disconnect the casing from the fan to remove the electric motor.

How to install a radiator?

After removing the radiator, replacing it or repairing it, you need to put it in place and secure it. Radiator installation is described in this article: How to install a radiator?

Installation of the cooling radiator is carried out step by step in the reverse order of removal.

First of all, we string the radiator itself and cover it with a fan and casing.
After tightening the nuts, connect the tubes, install the plugs, and connect the radiator fan.
Fill with coolant and close the lid.
We start it up, check our final result and that’s it.

Radiator repair

The most common reason for replacing or repairing a radiator is the loss of coolant due to the presence of a hole.

Typically, coolant leaks from the junction of metal and plastic. And if the leak is not large, then solving this problem yourself is quite simple. Along with the coolant, we add a special mixture to the radiator (sold in the store) and after a while the leak will go away on its own. Otherwise, you cannot do without purchasing a new radiator.

Checking the radiator tightness

To check the tightness of the radiator, do the following:

Fill the bath with water.
We plug all the holes in the pipes.
We lower it into the bath by 20-40 cm and apply pressure to the radiator in the amount of 0.2 MPa (2 kgf/cm 2 ).
We look at the result in the form of the presence or absence of bubbles.

Radiator replacement

Also, a forced replacement of the radiator occurs after the car is involved in an accident, both in a frontal and side collision.
