The heater valve in the car VAZ-2114 – this is one of the weaknesses of the cooling system. He breaks down so often that the majority of car owners, gain experience, without any problems on their own change it with new one. Why it crashes, and how to replace the heater valve vases-2114 step by step, we will discuss in this article.

What is and why you need the heater valve

This element represents a valve device designed to control the flow of coolant through the radiator. In the hot season, when the heater usually is not used, the driver overrides the faucet, and the hot antifreeze or antifreeze by bypassing it, not by heating a pumped or freely circulating air in the cabin. In the cold, on the contrary, the device is opened, freeing the path for the coolant to “stove”. Here in this simple way there is climate regulation in salon VAZ-2114.replacing the heater valve 2114 VAZ

The valve is actuated by cable from the control lever located on the center console of the car. The lever marked with a long red arrow at the bottom.

Crystals

The reasons of an exit of the crane out of action just two:

  • Welding (acidification) of the working parts of the locking mechanism to the shell or to each other;
  • Violation of integrity of the body (flow).

Given that its design is non-separable in any of these cases will require not just repair, and complete replacement of the heater valve VAZ-2114.

How to specify that the tap is broken

To Diagnose the failure easily. In the first case it is caused by oxidation of elements of the locking mechanism. This leads to the fact that he simply ceases to move in any direction.

Replacement heater valve

When you try to move the lever control valve it will not budge. Trying to break the mechanism, using the force, fraught with breakage of the lever, with breakage of a cable or a mechanical damage to the crane.

The tightness of the device is the cause of the failure of the seals, which are made of ordinary rubber that reacts with antifreeze, and antifreeze. To understand that tap drip, you can help the puddle of coolant on the floor Mat for the front passenger footwell or oily white film on the windshield, which is its evaporation. But in this case you'll need to make sure that the drip is the crane, not the radiator “stove”, or pipe.

Choose crane

Today car shops, you can buy three types of locking devices for the heater:

  • Standard (regular full-time crane car) with a metal locking mechanism and a rubber membrane.
  • Ball valve (with locking mechanism in the form of a movable sphere with a hole);
  • Ceramic (has a closing mechanism of the 2 ceramic plates).

A Standard crane to install you will not recommend none of the maintenance foremen. It will last for long, and the price is not very different from the upgraded models. Replacement heater valve VAZ-2114 on the ball will allow him to work a little longer, but completely will not solve the problem, as its locking mechanism is also metal.

Best proved ceramic device. They have a plastic case and a mechanism made of ceramic, not susceptible to oxidation processes. Such a device would work long enough if you do not fail the seals.replacing the heater valve vases

What should be at hand

In order to replace the heater valve VAZ-2114 did not take much time, it is better to prepare in advance the necessary tools and means. We will need:

  • A container with a wide neck to collect the drained coolant (no less than 5 l);
  • Cross screwdriver;
  • Slotted screwdriver;
  • Key 10;
  • Key 13;
  • Pliers;
  • 4 worm drive clamp 15-23 mm;
  • A tool to remove the rust (like WD 40);
  • Cloth.replacing the heater valve 2114 VAZ photo

In addition, the car will need to be installed on “hole” or on the overpass.

Next, we will explain how to replace the heater valve vases-2114. Photos of this process are presented in the article.

Preparing for the replacement process

Drove the car on the overpass, open the hood, Unscrew the filler cap of the radiator andthe tube on the expansion tank. Next, go under the car. At the bottom of the engine block find the plug to drain the coolant (not to be confused with the oil drain plug on the crankcase). Previously substituting an empty container, Unscrew it with a key 13 and wait until you drain all the liquid.

Then out from under the car and heading to the engine compartment. Replacement heater valve will be out of the salon, but first we need to Unscrew it from under the hood. In the engine compartment on the passenger side, find two pipes going into the cabin. Is the input and the outlet of the faucet. Weaken them to the clamps and disconnect them. Beside the nozzles there are two threaded studs and nuts. They are, in fact, fix the faucet. That the nut was easier to remove the treated studs liquid rust.

Replacement heater valve VAZ 2114 with his own hands

For convenience, the replacement of the crane, some masters and owners completely disassembled the instrument panel. To do it not necessarily. We will explain how to replace the heater valve VAZ-2114 without removing the panel.

The dismantling of the crane

Go to the car on the front passenger seat. To the left of the passenger's footwell there is a cover panel. It needs to be removed by removing screws Phillips screwdriver. Now that we have access to the radiator cap and heater tap, enclosed for them a dry rag. It is needed in case of spillage of coolant.

Screwdriver with a cross-shaped bat weaken clamps pipes to shut-off the device and disconnect them.

Next, replace the heater valve requires disconnecting the cable. Take the pliers and, holding them bracket thrust, flat screwdriver, disconnect the cable. Then move to the engine compartment.

The Key for 10 Unscrew the nuts that fasten the faucet. Then extracted the broken closure device from the front passenger side.

Installing a new heater valve

The Installation of the faucet in the reverse order. First, fasten it to the body, spinning the nuts on the studs, then connect the cable. The clamps on the pipes it is better to change to a new one. Pay attention to the condition of the hoses. If the ends are too stretched or there are cracks, it is better to replace them. If with them everything is in order, connect them to the faucet and then hold the clamps with a screwdriver. The cover panel in place until set. We will need to check the tightness of the joints with the engine running.

Here, in principle, and the whole process. As you can see, the replacement of the heater valve VAZ-2114 with his own hands is not such a difficult task.

Completion of work and integrity check

Upon completion, go back under the car and tighten the drain plug. Then pour coolant into the radiator neck, focusing on the level in the expansion tank.

Replacement heater valve VAZ-2114 requires a thorough check of tightness of connections at the end of repair work, and the master himself will be interesting to see how well it worked.

Start the engine and warm it before turning on the radiator fan. Without turning off the engine, check for leaks in places of joining of the pipes in the cabin and under the hood. If everything is fine, try to close and open the tap by moving the control lever when the heater fan. In the open position, injected into the interior air should be hot. This means that the locking mechanism opened, and the coolant passes through the radiator. When the valve is closed should go cold air. This will signal, that the locking mechanism has blocked the flow of coolant into the radiator “stove”.Replacement heater valve VAZ 2114 without removing panel

Some tips

  1. Replacement heater valve VAZ-2114 should be made in a very short time in identifying his faults. Especially if we are talking about coolant. And antifreeze, and antifreeze are toxic!
  2. Do Not skimp, choosing a faucet. Better take a good brand model that are not susceptible to oxidation, and use it 5 years, than every year to buy the device is of dubious quality and origin.
  3. Do Not use cheap fluids – their composition depends on the duration of work not only tap, but also the entire cooling system.
  4. If the tap was leaking in the cabin is the smell of antifreeze or antifreeze, and the glass has oily coating, please wash and dry your rugs or carpet, and to clean the glass with an alcohol solution.
  5. If the above process seems complicated, it is better to contact the service center.
