O-ring Quantity: 1 Location of use: Electric thermostat

Gasket Quantity: 1 Location of use:Electric thermostat

Warning:
– Never remove the cooling system cap or loosen the radiator drain plug while the engine is running, or when the engine and radiator are hot. Scalding engine coolant and steam may shoot out and cause serious injury. It may also damage the engine and cooling system.
– Turn off the engine and wait until it is cool. Even then, be very careful when removing the cap. Wrap a thick cloth around it and slowly turn it counterclockwise to the first stop. Step back while the pressure escapes.
– When you are sure all the pressure is gone, press down on the cap using the cloth, turn it, and remove it.

ELECTRIC THERMOSTAT HEATER INSPECTION
Warning:
– If the cooling system cap or the water-cooled charge air cooler reserve tank cap is removed when the engine is hot, steam and boiling water may be injected, causing severe burns or severe injury.
Note:
– Immediately after the electric thermostat heater is energized, the heater is in a heated state and the resistance does not stabilize. Wait for a sufficient time before measuring the resistance again.
Resistance Inspection:
1. Disconnect the negative battery terminal.
2. Disconnect the electric thermostat heater connector.
