Replacing the heater valve (heater valve) Niva VAZ 21213, 21214, 2131 lada 4x4

If necessary, replacing the heater tap 21213 Niva is carried out quite quickly at the nearest service station. Naturally, you will have to pay for the procedure according to the car service tariff. Meanwhile, the operation is not so complicated and labor-intensive that it would be impossible to do without skilled auto mechanics. This simple part can easily be changed independently; even an ignorant car enthusiast will need no more than 2 hours.

What to put in place

Before rushing to the store for a new part, you should first disassemble the assembly and make sure that the faucet is to blame for all the troubles.
It often happens that the seal between it and the heater radiator, where the rubber gaskets are located, leaks. They become limp and begin to leak coolant. The cause of jamming may be the rod attached to the element. Faucets made of metal or ceramic are available for sale. In terms of price, they are approximately the same; in terms of reliability, motorists praise ceramic ones more. In addition, you need to purchase 2 new gaskets and high-temperature sealant (usually red).

For reliability, some VAZ-21213 owners prefer to install a regular plumbing faucet with a diameter of 15 mm (DN 15), connecting it to the stove with flexible pipes. The option is reliable, since plumbing fittings are more durable than car parts. But then it’s better to forget about convenient controls, because every time you have to dive under the glove box on the front passenger side to open or close the valve. It is also installed on the engine side, under the hood, resulting in the same “conveniences”.

Lada 4×4 3D IROQUOIZ › Logbook › Inspection of the cooling system, replacement of the heater valve

All the domestic cars that I bought before (2 Volgas and a Niva) required a refurbishment of the cooling system from the moment of purchase, this Niva was no exception. I started by flushing because I didn’t know what kind of antifreeze was in there? This means that the new one must be filled in cleanly. Drained, green, clean without debris or dirt.

And the washing began. First, I changed 3 simple tap waters, our water is good, soft. Filled it up, started it up, turned on the fan 3 times, drained it. Then I filled it with distilled water and rolled it around a bit, drained it and took everything apart. During all these manipulations, I lost the drain plug from the block, damn it.

Well, here’s what you’d expect. All the pipes are cracked, the aluminum is oxidized, the clamps are rotten, every connection is sweating, etc.

The stove faucet is also snotty and dripping.

While I've disassembled everything under the hood, let me think I'll tighten the tensioner, I don't have a hydraulic one yet. I looked - yeah, something unfamiliar, I googled it - it turned out to be an original VAZ, automatic, so let it stand and work.

Looked inside the cooling system - beauty! Never before have I had such a clean engine from the inside.

The THOMSON thermostat seems to be set at 80 degrees right off the assembly line.

I cleaned off all the oxides and sanded the pipes a little with fine sandpaper. And no sealant! The point of smearing it is when it turns into sticky snot and gives no effect other than dirt!

Everything is completely ready for assembly.

I started with the stove tap. I use exclusively ceramics from LUZAR, article number LV0101

, the kit includes everything you need, but I left the bolts and washers from the factory.
I also bought an additional gasket 21010-8101332-10
for the second radiator pipe - it was not useful.

Before removing the old faucet, I dismantled the shelf, this is much more convenient. Installing a new one took 10 minutes, everything was quick and accessible. Why do people swear at him so much...

I started assembling the cooling system itself from the deepest connection, fortunately I removed the throttle, and all the pipes were removed, there is access. Gates hose 3225-00051

internal diameter 10 mm, galvanized clamps Norma
S12-22/9C7W1
2 pcs.

Then I collected all the pipes. Engine kit LUZAR LPK 01213

+ clamps Norma
S30-45/9C7W1
7 pcs.
– for all pipes and Norma S35-50/9C7W1
1 pc. – clamp of the lower pipe at the block.

Next, I left the original tank, just washed it. Branch pipe of PJSC “BRT” 21214-1303095-01

+ Norma
S16-27/9C7W1
2 pcs., but I replaced one on the radiator with 12-22, it was in stock.

While I was poking around I discovered a torn-off bracket for the manifold screen, just a note. May rattle during operation.

Well, I started working on the stove pipes. Also LUZAR, article LPKh 01214

and clamps Norma
S16-27/9C7W1
4 pcs.
Pipes from 21214 will fit on 2121-213, but vice versa - not. You cannot install 213 pipes on 21214
, because it will run into a black plastic twist, which is what I had and the pipe was all dented and burst.

Well, a new plug 21010-1305026-00

took her place.

I prefer to pour the first and main portion of antifreeze through the upper pipe, so about 6 liters enter the engine this way, and the rest through the expansion tank and radiator.

Antifreeze filled 10 l SINTEC LUX G12 756665

and 1 l SINTEC LUX G12
613500
as many as 2 pcs. I took it and was scared by the manuals, which say that the Niva holds 10.7 liters, almost like the Volga, damn it. No matter how much I filled it, there was no way until only 9.5 liters fit somewhere. Maybe the manuals and volumes were written for old copper radiators, which have a larger volume? How much antifreeze does anyone have?

Expenses:

Cooling system pipes (set) – 565 RUR; Worm clamp 30x45 7 pcs. – 210 rub.; Worm clamp 35x50 – 30 rub.; Heater pipes (set) – 145 rub.; Worm clamp 16x27 mm 4 pcs – 120 RUR; Expansion tank pipe of PJSC “BRT” – 75 rubles; Worm clamp 16x27 mm 2 pcs. – 50 rub.; Worm clamp 12x22 mm 2 pcs. – 50 rub.; Heater tap – 245 rubles; Heater tap gasket – 15 rubles; Antifreeze drain plug from the block - 20 rubles; Antifreeze (10 l.) – 1040 rubles; Antifreeze (1 l.) 2 pcs. – 290 rub.

What is a stove tap, its functional features and location

The stove tap is a metal part that resembles a regular water tap. Antifreeze (coolant or coolant) constantly flows through it.

In the Chevrolet Niva, the coolant can flow through 2 cooling circles: winter and summer. The heating tap gives the driver the opportunity to switch to one of them. For example, with the onset of summer, when the tap is fully open, it is almost unbearable to be inside the car due to the heat, so it is closed for this period of time, and with the onset of cold weather, the tap is opened again. Due to active use, the part eventually becomes unusable and leaks coolant.

It is very easy to determine whether a part is faulty - lift the cover in the Chevrolet Niva interior. If there are obvious signs of leakage, the unit must be replaced.

In the diagram you can see where the heater tap is located and the circulation of antifreeze in two circles

Why do you need to change the faucet?

In Niva cars, as in classic Zhiguli models, the heating intensity of the interior is controlled using a special tap. It is installed on the coolant supply pipe leading to the heater radiator. The stove tap is made in such a way as to open and shut off the flow in just half a turn of the rod. Thanks to this, the faucet can be controlled using a rod attached to a lever on the center console.

In reality, no one uses the heater valve as a regulator; more often it is used to cut off the heater from the Niva engine in the summer. This is where the following problems arise:

the faucet jams in one position, it is impossible to close it;
after a warm period, the tap turns sour and does not want to open;
the part begins to leak at any time of the year.

If you do not shut off the fluid flow in the summer, then the interior of the VAZ-21213 will become very hot. In the Chevrolet Niva, the faucet is missing as a weak link, and the stove is constantly heating up. The design of a regular Niva is not designed for this and the problem needs to be solved somehow.

The situation is the same in the other two cases, and due to a leak, harmful antifreeze vapors will accumulate inside the car. Since the design of the heater valve does not provide for its repair, the part only needs to be replaced.

How to replace a faucet on a VAZ 2101-2107 “classic”, “Volga”, “Niva”, “Oka” (work order)

The operations for replacing the heater valve on different cars are very similar and differ mainly in the need to dismantle some parts to gain access to the failed valve.

Note: the heater faucet from the Zhiguli also fits the Volga, Niva, and Oka cars.

Next, we will consider in detail the replacement of the tap on VAZ 2101-07 “classic” cars.

According to the instructions, before proceeding with the removal of the pipes, it is necessary to drain the liquid from the engine cooling system. This operation can be omitted, given the fact that the stove radiator and pipes are located above the level of the main radiator. It should be taken into account that some of the coolant will still leak out, so you need to have a small container on hand.

Use a screwdriver to loosen the clamps and remove the hoses from the heater radiator pipes. Do not forget to place a container under the hoses to drain the coolant leaking from the pipes.

Using a key “8”, unscrew the two screws and remove the seal from the radiator pipes.

In the car interior, remove the instrument panel shelf. For convenience, remove the glove box body. On VAZ 2104, 2107 with an instrument panel with side air ducts, it is also necessary to dismantle the air duct by unscrewing the nut to “10” and prying the latches around the perimeter with a slotted screwdriver.

Using a key set to “7”, loosen the screw and disconnect the heater tap drive rod (1).

Typical radiator malfunctions

There are two main radiator malfunctions:

Clogged grille and radiator tubes.
Radiator leakage.

Since the Niva is often operated in difficult road conditions, the likelihood of contamination of the grille from dusty outside air is very high. Clogging of the cells reduces the heat transfer area of the radiator, and as a result leads to a decrease in the heat released from the air ducts into the passenger compartment. In such cases, the stove radiator is dismantled and washed under high pressure.

Clogged radiator tubes are also common. If the outlet pipe is barely warm or cold, then the radiator tubes are clogged. This happens for various reasons, including the entry of foreign objects into the cooling line during repair work. In such cases, the tubes themselves are also washed. To do this, it is not necessary to remove the heater radiator. It is enough to separate the radiator pipes from the cooling system and supply water under pressure into one of the radiator pipes.

A leak in the radiator tubes can be determined by a coolant leak, which usually forms on the right side of the center console in the passenger foot area. As a rule, a leak is accompanied by the smell of antifreeze (antifreeze) in the cabin. Don't rely on the smell of antifreeze alone. Coolant vapor is very volatile and can be misleading as to the source of the leak. The smell of antifreeze also indicates a leak in the engine compartment.

The leakage of the heater radiator occurs due to natural wear and tear of the metal from which it is made. Constant cycles of heating and cooling, exposure to various chemicals and consumable liquids eventually lead to the destruction of the metal and the formation of cracks. Cracks in a copper radiator can be soldered. The aluminum radiator will have to be replaced with a new one.

The ball one (it comes with 2108999 from the factory) suffers from a leak along the axis, the ceramic one with two slots does not leak, does not sour, but there is an opinion that it has a smaller cross-section, etc. But I washed the stove with a faucet under the water supply and I can say with authority that a ceramic faucet easily passes such a pressure that a standard pump will not create, not an ATE-1 electric pump with 1800 hp.

The standard pipe from the water supply created a stream of 3 meters in both directions and the tap was not a hindrance, although I read about reducing the cross-section and thought about removing it when flushing, now I’m sure that this tap is more than complete, especially since Luzar says that the maximum design quantity is in the slurry pumped through the stove is equal to = 1000 lch, for comparison, I checked how a new pump from a gazelle pumps, produced by KZATE (which is 1400 lph) and a short-circuiting one, produced by ATE-1, and so both hit about 30 cm, and the water supply by 3 meters, with the same diameter of the pipes, the difference, as they say, is obvious.

Removing the radiator of the VAZ-2121 stove

The procedure for removing the heater radiator on a VAZ Niva does not require any special skills or abilities. It is important to prepare the necessary materials and tools in advance. Most instructions for repairing car heaters contain a recommendation to drain the coolant before starting work. In practice, many car enthusiasts limit themselves to draining only that part of the antifreeze that is located in the radiator itself and the nearby pipes of the cooling system.

Preparing tools

To replace the radiator, you will need the following tools:

pliers;
slotted screwdriver;
Phillips screwdriver;
a set of markers for identifying wires;
spanner set to “7”;
socket wrench set to “10”;
socket wrench set to “7”;
socket wrench set to "10".

Procedure for dismantling the radiator

All operations must be performed in the following sequence:

Unscrew the left self-tapping screw securing the storage shelf.

The self-tapping screw is unscrewed with a Phillips screwdriver

The right side of the shelf is attached to the upholstery

The central part of the shelf is unscrewed from the front panel

The right edge of the shelf moves down freely

There is a special spike on the left side of the shelf

The lower part of the panel is also fixed with a self-tapping screw

The process is shown on the right side, the left side is similar

The panel is moved to the side

The wire blocks are detached to remove the entire radio panel

After disconnecting the wires, the panel can be easily removed

Loosening the clamp is shown using the example of the lower pipe; a similar operation is performed with the upper

The staples are pryed off with a slotted screwdriver

The casing with the fan is moved to the side

After removing the fan, the radiator is carefully removed from its compartment

The tap and pipes are turned off with a key to “10”

The removed tap is checked for leaks

The bottom nut often falls out and gets lost

Disconnect the outgoing pipe.

The two fastening nuts are unscrewed with a “10” wrench

After dismantling, you should carefully inspect the radiator for blockages in the grille and leaks from the tubes. Based on the results of the inspection, a decision is made on the possibility of repair or installation of a new radiator.

Video: installing a radiator

The process of replacing the heater radiator on a classic Niva has been studied far and wide by many car owners. In fact, the procedure is similar to the entire family of AvtoVAZ classics. However, caution and safety precautions should be observed when working. After completing the repair, before driving on public roads, you must make sure that all components and mechanisms of the vehicle are operating normally. Only then should you begin daily use of the machine.

For what reasons is a Chevrolet Niva crane replaced?

In a car, the heating valve is a maintenance-free unit, so it is necessary to change it for both technical and financial reasons. If the faucet breaks down, it is only thrown away, and the causes of the malfunction may be as follows:

Violation of tightness. When the elements rub, they wear out and therefore no longer fit together as they should. As a result, various smudges appear, which are very noticeable.
Internal oxidation of elements. In summer, the stove tap is closed for a long time, so during this period its elements oxidize and stick to each other. Consequently, it is almost impossible to open the tap without breaking it.

On a Chevrolet Niva, the heating valve for the heater is located in the wall of the engine compartment, so when you open the hood of the car, you will see a pipe that goes to the valve adapters from the radiator. To get to it, you need to dismantle the dashboard in the cabin on the passenger side.

The stove valve is mounted in a special niche in the engine compartment

If the faucet has been replaced, then it is better to install new pipes along with it, because during operation they have probably already lost their elasticity.

Let's sum it up

As you can see, on all modifications of the domestic Niva SUV, the interior heating system works extremely poorly, and this is mainly due to its design flaws. For this reason, vehicle owners have to constantly look for different ways to solve the problem, constantly upgrading the stove in the car.

As practice shows, it is not difficult to correct all the shortcomings and improve the interior heating. Any driver can carry out the procedure for independently tuning the interior heating system in a Niva-21213 car.

Procedure for installing a new part

Due to the fact that the heater radiator is located above the engine, part of the coolant does not flow out of it when it is emptied. And even more so it is full when the old tap is stuck closed. So before disassembling the unit, you need to stock up on a plastic bag without holes: it is convenient to place it in places with limited access.

Disassembly and removal of the tap are carried out in the following order:

From the engine compartment, you need to loosen the clamps of the pipes leading into the cabin, and then remove them from the fittings.
Unscrew the screws holding the sealing gasket (key 8) and remove it.
From the interior of the Niva, you need to get to the tap and disconnect the rod by unscrewing the clamping bolt (key 7). Place a plastic bag to catch the remaining antifreeze.
Loosen the bolts securing the faucet to the stove (key 10), unscrew them and pull out the part along with the metal pipe. If the heater radiator is copper, of the old type, then instead of bolts there will be nuts.
Separate the metal pipe from the old faucet by unscrewing 2 nuts (10 wrench). Remove the traction mount from it.
