Installation of an additional heating device in a VAZ-2114 car

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:

1. Replace the coolant and flush the entire cooling system.
2. Replace the interior heater radiator with a new one.
3. Replace the engine cooling radiator with a new one
4. Change the pump.
5. Remove air from the cooling system.

Specific examples

The painted copper radiator on the VAZ 2114 deserves special attention in the debate about which heater radiator is better, copper or aluminum. By the way, these are made by an office called “LUZAR”. There is no need to take such units: they are very cold, and have minimal heat transfer! But such devices have a full year warranty.

Why is everything so bad with Luzar? An autopsy will show: the rubber band, which is located next to the passage channels of the ribs, simply becomes damp after a relatively short period of time (less than a year) and the same short mileage. Another big disadvantage of Luzarov radiators is that the pipes are separated from each other, this reduces heat transfer, but makes the cost advantageous.

In general, it is now difficult to find a zero radiator that is relatively recent. Factory junk will crumble, radiators from the manufacturer are not always of decent quality. Therefore, the guideline you can choose is very simple (when choosing a radiator): it just has to be working and not clogged. And what material it is made of is the tenth thing.

Another company, DAAZ, has proven itself very well. There is only one minus - try to find it, and then try to find the original. By the way, the heat output of the Daazov heater is slightly lower than the factory one in the VAZ. And in terms of quality it clearly wins.

Another example is a heater from Oberkraft. The factory carefully approaches the testing process of the unit, which is why it is covered by a good warranty (one year). This device is made of aluminum alloy, which meets modern quality standards. An obvious advantage is the good, uniform distribution of heat throughout the cabin (apparently, they decided not to skimp on pipes), but considering the price, you can’t say that this is an easy purchase – from 1,800 rubles. But there are justifications for this price:

1. Corrosion resistant
2. Relatively light in weight
3. Very important: resistant to temperature changes!
4. Robust design
5. Excellent and uniform heat dissipation.

In winter, even the highest quality stove will play tricks in terms of heat output. We offer a couple of good tips on how to make the interior warmer:

• You need to change the antifreeze and rinse the entire cooling system - this will remove all the debris in the tubes, making it easier for air to enter the cabin
• A great way to improve the microclimate is to install a new stove!
• You can also replace the cooling radiator with a new one - this will save the antifreeze from premature fatigue
• An option is to replace the pump, because it is responsible for the stability of coolant circulation at idle
• Run all the pipes and get rid of air pockets

As strange as it may sound, the stove can be insulated. Yes, for example, after running the entire system, you can glue all the joints, then the heat through the pipes will be precisely directed through the channels towards you, and not spread in an unknown direction. Another way: change the mode of air intake from outside to recirculation (why it is worth explaining this elementary action as one of the ways: yes, because many people think that the stove needs to be plugged! But the air intake does not come clearly from under the hood, which is what they are trying shut up, but just from outside!

So, as soon as such a crazy thought appears in your head, change the air intake mode). The last option for preserving heat is to insulate the interior itself. A very logical action, especially considering the presence of gaps around the body on the fourteenth.

Which is better?

Of course, it is best to choose radiators of proven brands or original LADA spare parts. As a rule, such spare parts are not cheap and not everyone is ready to pay a tidy sum for a radiator when you can buy the same part, a little worse in quality, but several times cheaper.

Everyone knows firsthand that copper radiators are much better than aluminum ones, but this statement is closer to stove radiators, since copper radiators actually have greater heat transfer than aluminum ones. In a cooling radiator, this will not play a big role, so you don’t have to overpay for a copper cooling radiator and feel free to buy an aluminum one.

Cooling system design

The VAZ 2114 is equipped with forced circulation CO. As a cooling system, you can take the most common substances antifreeze and antifreeze. In emergency cases, you can use water instead of specialized automotive substances.

Note: In winter, using vehicles filled with water instead of special liquids can lead to freezing of the engine. And in other seasons, during prolonged use of vehicles, the cooling jacket in the block and cylinder head begins to corrode the engine on the water, and rusty sediment accumulates.

The engine cooling system consists of the following elements:

Price and article

The table below shows several good manufacturers, the price of their products and the article number by which you can find and purchase this part.

What mechanical failures can occur in the cooling system?

Usually, due to unexpected breakdowns in the engine cooling system, overheating can occur and as a result, the car engine breaks down.

As usual, any of the following parts may fail to work:

Radiator. Possible leakage from the radiator is leakage through aluminum tubes or plastic tanks. It happens quite often that the plastic parts of the outlet under the return hose of the expansion tank break off.

But there is another problem that probably causes the motor to overheat - clogging (clogging).

Pipes. If the pipes are old and have lost flexibility over the years, this is also a possible cause of antifreeze leakage.

Thermostat. The necessary operation of the valve in the thermostat depends on its correct operation, and in the internal combustion engine itself the following may occur:

• If overheating occurs, the antifreeze boils away through the expansion tank.
• The car does not warm up to the required temperature. Subsequently, the car drives unstably, and in winter the car dealership is cold even with the heater on.

Replacement of cooling radiator VAZ 2113, 2114, 2115

During vehicle operation, various damage to the cooling radiator is possible, as a result of which the coolant level decreases, which in turn can lead to engine overheating and costly repairs. Therefore, if a VAZ 2113, 2114, 2115 needs to replace the cooling radiator, there is no need to hesitate - we buy a new one and carry out the repairs ourselves, following the step-by-step instructions in the photo and video.

Refinement of the pipe

When the air flow from the left deflector is too small, you can force its intensity. To do this, you need to insert a small (about 50 mm) fan into the pipe. A cooler used in computers is suitable for tuning.

First remove the deflector. Make a hole for the cooler and install it. Seal. Put the branch pipe with the fan in place. Restore electrical. An alternative is to connect the cooler directly to the heater contacts. In this case, it will only work when the ignition is on.

Properly carried out modernization will add warmth to the interior and save the owner of the VAZ 2114 from many problems.

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.

When Rework Is Needed

This situation often happens: when trying to reduce the temperature, hot air blows from the torpedo. But from the air ducts located on the sides, a cold flow of air flows onto the windshield. Necessary:

1. 1. Remove the side cover of the torpedo on the gas pedal side. Here you will find the throttle cable. It is secured with a clamp. Loosen it and, pulling the cable down, fix the clamp again. Now you need to set the damper control levers. Left - to the right, and right - to the left. The crane control lever itself must be set all the way to the right. At this moment, warm air should come out of the side holes.
2. 2. The second stage of tuning is to ensure that outside air passes through the heater. Since one engine is responsible for the operation of the damper and the tap, it is necessary to block its control of the damper. Remove the dashboard cover on the right side and disconnect the temperature control cable from the engine. There are two of them here. Disconnect and tighten the one on the right. At this moment the damper should be in its maximum position. Bend the tensioned cable at the attachment point and cut off the excess length.

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.

The most common mistakes of those who choose a particular radiator model

Some car owners prefer units. It is not worth buying such devices. The fact is that they have practically no heat transfer! The warranty on units from this manufacturer is 12 months, but the efficiency of such radiators is practically zero.

Sometimes car enthusiasts prefer heaters from. These devices are quite efficient. Manufacturer's warranty - 1 year. These radiators help distribute heat evenly throughout the car's interior, but the cost of these units may seem overpriced.

Advice! Some car enthusiasts are faced with another problem. It turns out that even buying a fairly high-quality radiator may not give the expected result. In order for the stove to work effectively enough, you need to change the antifreeze in advance, and then rinse the cooling system of the machine. In a similar way, you can get rid of various debris in the tubes. This is extremely important, because only after this procedure the air entering the cabin will become cleaner.

We can also recommend replacing the pump. This unit is responsible for how coolant circulates in the car at idle.

Some experienced motorists also recommend getting rid of all air jams.

How to choose a radiator for a VAZ car

The design features and operating principle of all automotive heat exchangers are absolutely identical. The cooling radiator is an integral component of the cooling system, the functions of which are aimed at ensuring normal temperature conditions for the operating internal combustion engine. The temperature regime is ensured by cooling the liquid circulating in the system. The location of the heat exchanger in the vehicle structure provides for direct contact with the oncoming air flow, facilitating an optimal heat exchange process.

The cooling process occurs due to:

CHOICE

So which heater radiator is better, copper or aluminum for a VAZ 2114? Let's consider the disadvantages of each manufacturing material.

Copper or aluminum?

What can you say about the aluminum stove radiator? Aluminum has good thermal conductivity and therefore heats up quite quickly. True, it also cools down almost immediately. Therefore, when you turn off the engine, the cabin of the 2114 will become cold after a while.

A solid (or prefabricated) heat exchanger has plates as a heat exchanger, and inside them there are tubes through which coolant flows. The tanks on the part are plastic. This design is the cheapest, but the heat transfer is low. Such spare parts are products of a non-original manufacturer. In a non-assembled radiator, the heat-dissipating element is a corrugated tape. The tanks of the product are soldered and are often made of metal. But the soldering is factory-made, and it is very problematic to repair a leak in aluminum using a makeshift method.

Brass (copper) radiator VAZ

The thermal conductivity of brass (copper), in contrast to its aluminum counterpart, is 65% higher. The main advantages of a brass heat exchanger include such factors as resistance to corrosion, the ability to carry out repairs at home in the event of minor damage resulting in a leak. The main disadvantage is its cost. The price of a brass radiator is one and a half, or even two times higher than its aluminum counterpart.
