Where is the Paula heater valve?

Pacific Auto Network Volkswagen Bora warm air opening mode: 1. Adjust the cycle mode of air conditioner to in-vehicle cycle. 2. Use the temperature adjustment button to raise the temperature. 3. Press the air conditioning button, and then adjust the appropriate wind speed and direction. The temperature controller is generally located at the joint between the sewer pipe and the engine, and the Bora temperature controller is located at the joint of the pipe near the engine and installed at the joint of the pipe.

Thermostats are usually located at the connection between the sewer pipe and the engine.

The new Bora thermostat is installed on the pipe joint next to the engine. Thermostat is a valve that controls the flow path of coolant. It is an automatic temperature regulating device, which usually includes a temperature sensing element, which opens and closes the flow of air, gas or liquid through thermal expansion or contraction. The thermostat works as follows:

1. Paraffin is a solid at room temperature. When the water temperature is lower than 76°C, the main valve is completely closed and the bypass valve is completely opened. The water from the cylinder head directly enters the water pump through the bypass pipe, so it is called small circulation. Because water only flows between the water pump and the water jacket, without passing through the radiator, and the flow rate is small and the cooling intensity is weak;

2. When the water temperature of the engine reaches above 76℃, paraffin gradually turns into liquid, and its volume increases, forcing the rubber tube to contract, thus generating upward thrust on the lower cone surface of the central rod. Because the upper end of the rod is fixed, the central rod generates downward reverse thrust on the rubber hose and the inductor, overcomes the spring tension, makes the main valve gradually open, and the opening of the bypass valve gradually decreases;

3. When the engine water temperature rises to 88℃, the main valve is completely opened, the bypass valve is completely closed, and all the cooling water flows through the radiator, which is called a large cycle. At this time, the cooling water has long streamline, large flow and strong cooling intensity.
