CIRCLE OF "ANTOSOLA"

The engine cooling system in winter is sometimes more capricious than in the summer. Radiators and pipes flow, electric fans and sensors fail, jammed thermostats make themselves known. And we set off on a frost in a shopping tour …

On the "Lada" radiator woke up. "Tosol" is consumed like gasoline. What to do?

The copper radiator can be soldered - although this does not always bring the desired result. It is better to take aluminum immediately to the trash - it is unlikely to be able to fix it in a garage. And if the part is old, all the more it makes sense to think about buying a new radiator. I will not advise sealants and folk remedies - when the flow is strong, they are ineffective, moreover, they pollute the cooling system over time.

So, for the "Lada" I can offer four types of radiators. The first - copper "cheap" - differs from modern analogs in fastening. The rest are both copper and aluminum. If you change one to another, do not forget to buy inlet and outlet rubber pipes. The radiators for VAZ 2105 and 2107 are almost the same: the difference is that the first is blown by a mechanical fan, the other by electric. Therefore, the "seventh" has a hole for the sensor. The original detail of the “shah” closes the four.

On samara injection radiators there is no fan sensor - the latter is monitored by the electronic unit. You can supply the part from the carburetor model by placing a plug in the hole - for example, the sensor itself (in this case, the faulty one will do).

There is no radiator for Svyatogor?

What engine is your hero with? Cars with Ufa and VAZ engines inherited radiators from Moskvich-2141. By the way, have you ever seen a part for a two-liter UZAM? Here it is - a little thicker than usual. For those who choose a car with a Renault motor, I propose a "native" one. Trying to adapt to the "Frenchman" is not worth the domestic radiator: a lot of alterations and it is not known whether the engine will like it.

I just can’t find a regular radiator for my Volga …

On all models except GAZ 3102, until 1997 a unified copper heat exchanger was used. At “zero second, ” there were two options: light green aluminum and copper, completely interchangeable. A few years ago, a new aluminum radiator with a plastic tank appeared on GAZ 3102, 31029, which also fits all the old Volga … except for the early zero-second ones.

At first, a copper radiator was placed on the GAZ 3110, a copy of the "twenty-fourth", only with an opening for the fan sensor. The current “Volga” comes from the factory with an original aluminum radiator, which easily stands up instead of its predecessor.

I saw imported radiators. Are they better than ours?

According to customer reviews, among foreign marriage less. On the market, in addition to domestic ones (for example, Orenburg Radiator JSC and DAAZ), there are many Iranian radiators, under the “brand” of which they also sell goods from Turkey, the United Arab Emirates, and China. In principle, the producing country does not play a special role - the quality of all is approximately the same, as, however, the price is one and a half times higher than that of the Russians.

Is it true that the electric fan from the VAZ 2106 is suitable for the “forty first”?

Yes, the node is universal. Electric fans appeared on the VAZ 2103, and then migrated to almost all VAZ models, Muscovites-2141 and some Volga cars. But diffusers, in most cases, each model has its own.

Many Bosch electric fans are now installed on Boshevsky electric fans, which are approximately five times more expensive than Russian ones. If you are not able to lay out a thousand-plus rubles for a German part, put a domestic one - assembled with a casing, they are interchangeable. The fan for Svyatogor with the Renault engine is in short supply, and it will not be possible to replace it with a domestic one.

I want to put on the "five" electric fan instead of a mechanical one. What do you need to buy?

First, pay attention to the radiator: does it have a hole for the sensor. It happens that on the VAZ 2105 put the "seven" with a stub. If not, change (redo) the radiator itself or bring the fan to a separate button. Of the spare parts you will have to buy: an electric fan (200–300 rubles), a casing for it (50–80 rubles), a sensor (30–60 rubles), a relay (10–20 rubles). Remove the old fan from the pump pulley and the plastic casing from the radiator; put the electric fan with a diffuser and screw the sensor. In the mounting block there is a regular place under the relay, and the wiring diagram can be found in any book on VAZ cars.

How to distinguish fan sensors? They all look the same …

The sensors on one of the turnkey faces have two numbers: these are the values ​​of the on and off temperatures. For “Muscovites-2141” - 87–82 ° С, “Lada” - 92–87 ° С, “Samar” - 99–94 ° С. On the "Volga" equipped with an electric fan, a "Zhiguli" is installed, and the "Svyatogor" with the Renault engine has its own sensor, but any of the above is suitable for the thread.

In addition to domestic, Kaluga, for which they ask 30-60 rubles, there are also imported ones, for example, the English company QH, at a price two to three times more expensive than Russian ones.

The car warms up for a long time - it seems that the thermostat has jammed in the open position. Which advise?

Here is the VAZ series: 2101 - for the Lada and VAZ 2121 3; 2121 - for the old "Niva"; 2108 - for carburetor "Samar" and "Oka"; 2110 - for the "tenth" family; 2112 - for front-wheel drive models with injection engines.

To "Moskvich-2141" with a "Zhiguli" engine, the thermostat from VAZ 2101 is suitable, with the Ufa - from the predecessor, the "fortieth". And here is the original part for Renault engines.

Not so long ago thermostats with a plastic case appeared on some models of the VAZ and Moskvich. By design and price, they are exactly the same as metal ones.

There are three “Volgovskiy” thermostats: for the “twenty-fourth” motor, for the ZMZ-402 and 406. The design is collapsible, so you can not change the assembly, but buy only the stuffing - it will cost two to three times cheaper.

I’m buying a third pump: two or three thousand go and scatter …

Not otherwise, you came across a “left” product. A normal factory pump lives at least fifty thousand, or even more. Choose: here is the original one for the Lada and VAZ 2121, and this is the assembly for the VAZ 2121 3 with a modified impeller. The performance of the latter is greater, the seats are the same. Having bought a water pump without a case, you can save 30-60 rubles.

On all front-wheel drive VAZs, except for cars with sixteen-valve engines, the plant installs "figure-eight" pumps. By the way, come across imported "Zhiguli" and "Samara" water pumps, such as Graf, Hepu, QH, Lockheed. Some are comparable in price to domestic ones, but most are two to three times more expensive.

You will have to search for a water pump for the Renault engine - I have never seen such a spare part on the market.

There are three “Volgovskiy” pumps, as well as thermostats: for each engine its own. For ZMZ-24 and 402 it is better to take Ivanovo products, for a sixteen-valve - “native” Zavolzhsky.

What kind of strange expansion tanks do you have?

"Moskvich", a new sample. It is with such machines that they are now leaving the assembly line. They say that they are stronger. Price - as with previous, interchangeable parts with them.

To the owners of Samar I offer an expansion tank with an opening for a coolant level sensor. Want to put yourself in a car? Buy the sensor itself and put a signal light on the dashboard - now you can control the level of Tosol without looking under the hood.
