What is a Coolant thermostat housing?

It is a critical part of the engines cooling system regulating the flow of coolant to maintain the optimal operating temperature.It includes the thermostat,housing and at times a temperature sensor,gaskets and seals.

Types of Thermostats

Car thermostat is divided into two, namely without a bypass valve and with a bypass valve.

1. Thermostat Without Bypass Valve

This type of thermostat is usually used in old cars, it is very rare for new cars to still use this type. This thermostat can be found on the radiator inlet and is still not equipped with a spare line that can make cooling water flow when there is a malfunction in the thermostat. Water will be trapped in the radiator and water jacket when the car engine is cold.

The advantage of this type of thermostat is that it is cheap. However, there are some drawbacks as well. In the event of a malfunction, a thermostat without a bypass valve has no safety line. In addition, there are no water lines that will cool down when the car engine is at high temperatures.

2. Thermostat With Bypass Valve

Unlike the previous type, thermostats with bypass valves are common in the latest cars. This type of thermostat can be found at the radiator outlet and has a bypass valve that is integrated into the thermostat. In this type the water coolant cannot circulate in the radiator but will flow from the water jacket to the thermostat which will enter the water pump and be pumped back to the water jacket.

The advantage of this thermostat with a bypass valve is that there is a safety line when there is damage and can immediately cool the hot engine temperature because it has a bypass valve. Meanwhile, the drawback is the price is fairly expensive because it has a fairly complicated construction.

WORKING PRINCIPLE OF THE THERMOSTAT

When starting a cold engine, the coolant temperature is equal to the ambient temperature, which means that it is significantly lower than the operating temperature.To speed up the warm-up of the system, the thermostat remains closed blocking the fl ow of coolant through the radiator directing it only to the water jacket of the drive unit (the so-called small circuit). As the temperature rises, the thermostat valve begins to open allowing fluid to flow through the main radiator (the so-called large circuit).

Functions of the thermostat

BASIC FUNCTIONS OF THE THERMOSTAT INCLUDE:
1.Ensures optimum engine operating temperature
2.Prevents overheating of the drive unit
3.Prevents under heating of the drive unit
4.Increases the efficiency of the drive unit and reduces
harmful emissions.Volkswagen VW Audi Car Spare Parts
