In addition to this spare part there is also a water pump, radiator, a lot of sensors, cranes, etc. The most important task of this system is cooling and warming up the engine. If the system does not function properly or even fails, this will greatly affect the wear of the engine of the machine. Replacement of the thermostat "Gazelle" will be necessary in most cases.

Characteristics of the cooling system

It starts with a description of the normal operation of the entire system as a whole. When the thermostat is operating properly, it maintains the coolant temperature in the range of 80 to 90 degrees Celsius. In addition to it, the same is responsible for the fan assembly, which is automatically turned on by the system in the case when the temperature of the liquid heating reaches 92 degrees or more. The fan will work until the thermal values of the liquid fall to 87 degrees. It should be said that in the cold season, the tubes through which the coolant circulates are covered with special covers. If there is any malfunction, the temperature will be greatly increased. In order to notify the driver, there is a warning light that lights up if the temperature reaches 104 degrees or more. If this happens, then immediately stop the vehicle, cool it, and then tackle the cause of overheating.

Description of the thermostat on "Gazelle 406"

The thermostat installed on the "Gazelle" of this type is two-valve, and has a solid filler. The location of this part is the exit of the cylinder head. In addition, the thermostat is connected with hoses with a radiator and a water pump. If you replace the thermostat yourself with a "Gazelle" it is necessary to know. Opening of the valve for this part occurs if the engine warms up to a temperature of 78-82 degrees Celsius. If the heating reaches 94 degrees, the valve opens completely. If it is closed, the system is also closed, and the circulation passes by the radiator. If the main valve of the thermostat is fully open, then the additional one closes, and the liquid passes through the cooling radiator.

Replacement of the thermostat with "Gazelle"

The need to replace this part arises when there are problems with heating or cooling the engine. In order to find out the exact cause, it is necessary to start the engine, and by hand try the lower radiator hose, through which the liquid flows. Initially, it must be completely cold. If at a temperature of 85 to 92 degrees the tube does not begin to heat up, hence, it is necessary to replace the thermostat.

• The first thing to do is to remove the cork from the radiator expansion tank, and then drain all the liquid. When the liquid is drained, the plug must be returned to its original position.
• After this, it is necessary to loosen the two clamps, which are located on the lid nipples from the thermostat.
• Then the hoses are removed from the nozzles.
• After that, you will see three bolts that you need to unscrew and remove the thermostat cover.
• Then remove the fixing plate. In order to do this, it is necessary to overcome the resistance of the spring, lower the lid down, and then turn in any direction. This is necessary for the lid to come out of engagement with the grooves and it could be removed.
• After that, the thermostat is removed from the cover.

The cost of a thermostat

The price of the thermostat on the "Gazelle" will depend on the operating temperature of this part. To replace the thermostat with "Gazelle" it is necessary to choose the one suitable for future operating conditions. The cost of this spare part starts from 50 rubles. The higher the temperature, the more expensive the thermostat will be. The cost of a good part is 250-300 rubles.
