Vernet thermostat: customer reviews and service

The thermostat is an integral part of the engine cooling system. It holds the coolant until the engine warms up and opens when it reaches a certain operating temperature (usually 95 degrees). The part is in an aggressive environment, and is also constantly heated and cooled. Over time, this leads to the destruction of rubber seals and valves. Such a device can not hold the pressure. Let's look at the Vernet thermostat, reviews about it and other useful information.

The company "Vernet"

This organization appeared in 1927 and was called CALORSTAT. After a while it was renamed "Vernet", as it is called today. For many years of production of auto parts, the company has become very popular. Today, more than 13 million units of spare parts are produced each year. To achieve such results was possible due to the almost complete automation of the process and close cooperation with the leading automakers.

Thermostats of this company are affordable and at the same time are of high quality. In addition, their service life is often higher than the declared one. Let's look at how good the Vernet thermostat is. Feedback from consumers will help us.

Quality at an Affordable Price

Often we have to choose between the original and Chinese parts. The former usually have a high cost, and the latter - a low quality. The best option in this case is to find a quality substitute. To do this it is quite simple, for example, with the help of spare parts catalogs.

Why is it better to buy a Vernet thermostat? The reviews he has for the most part are positive. The drivers note a fairly humane price tag and excellent quality, which confirms the duration of operation. The product is made of brass and copper and has a good appearance. Although before buying still carefully consider the product for the presence of mechanical damage is needed. Of course, it will not work. Although this can be done directly on the car, if the valve does not open, then the product must be returned to the store.

How to remove the thermostat and put a new one?

Dismantling the product is quite simple. For this we need a set of spanners or car keys. Next we find the thermostat. It is installed in a special housing and is located above the radiator or on the side of the engine. Above it is installed a filler cap, which serves to keep or relieve pressure in the system.

After you find the body of the thermostat, unscrew a couple of nuts and remove the upper part of the body. Before that, it is possible to pump out a little of the antifreeze from the neck, so that it does not spill and does not fall on the belts and rollers. We dismantle the case, we take out the old part.

Since it is quite easy to connect a thermostat, it makes no sense to describe the procedure in detail. All actions are performed in the reverse order. It is worth noting that it is recommended that when changing the thermostat, replace the filler cap, since it may also not hold pressure or reset it due to the jammed valve.

Checking the health of the device

Such spare parts for machines, like a thermostat, are inexpensive, but these are the nodes that cause the engine to overheat, which leads to serious consequences. Therefore, the condition of the thermostat should always be monitored, if it works, then you do not need to change it.

There are several ways to check. We start the car and completely warm up the engine. We deafen and open the hood. We see two thick pipes going to the radiator. Check the upper and lower. Both must be hot. If the bottom is cold, the thermostat did not open and the radiator is closed. In this case it makes sense to talk about jamming the device in the closed position. In this scenario, you can overheat the motor, regardless of whether it's cold or hot outside. If it jams in the open position, the car will warm up very long. That's why such spare parts for cars are better to take good quality and not save on them.

Valve actuation temperature

The principle of the device is the presence of a wax ball inside the cylinder. A metal pin is inserted into it, which presses against the valve. When the temperature rises and the wax begins to melt (expand), the pin is squeezed out and the valve opens.

The whole point is that on different cars this temperature is different. That's why you need to be able to choose the right thermostat. To do this, it is better to take the old one, find a number on it and select an analogue through the catalog or purchase an original thermostat. "Ford Focus" - a car in which the thermostat opens at 95 degrees, and on the "Dodge Stratus" - at 97. It would seem that the difference is insignificant, but in one car the engine body is cast-iron, and for the second - aluminum. Naturally, short-term overheating in the first case will not be as fatal as in the second.

Let's sum up the results

As you can see, the device is small, but it performs a very important function. If such a node fails, the engine may overheat both without serious consequences, and with them. Buy the Vernet thermostat. Reviews about it are mostly positive. The cost of such a part is about 2000 rubles. This is not the most expensive or cheapest option, but one of the best in terms of price and quality.

If you decide to replace the thermostat yourself, and for several years the cooling system has not been serviced, we recommend cleaning the radiators, replacing the antifreeze and the filler cap. All this is not so difficult, but it is extremely important for normal operation of the car at any time of the year.
