If the system does not function properly or fails altogether, this will greatly affect the wear of the machine's engine. Replacing the Gazelle thermostat will be necessary in most cases.
Characteristics of the cooling system
It's worth starting with a description of the normal operation of the entire system as a whole. When the thermostat is working properly, it keeps the coolant temperature between 80 and 90 degrees Celsius. In addition to him, the electric fan is also responsible for this, which automatically turns on the system when the liquid heating temperature reaches 92 degrees or more. The fan will work until the thermal performance of the liquid drops to 87 degrees. It is worth mentioning that in the cold season, the tubes through which the coolingliquid, covered with special covers. In case of any malfunction, the temperature will rise greatly. In order to notify the driver about this, there is a warning light that lights up if the temperature reaches 104 degrees or more. If this happens, then you need to immediately stop the vehicle, cool it down, and then deal with the cause of overheating.

In addition, the thermostat is connected by hoses to the radiator and water pump. When you independently replace the thermostat with a Gazelle, you need to know this. The opening of the valve of this part occurs if the engine warms up to a temperature of 78-82 degrees Celsius. If the heating reaches 94 degrees, then the valve opens completely. If it is closed, then 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.
