Home  id0112hf801500

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. Perform the removal of the cooling system cap and water-cooled charge air cooler reserve tank cap when the engine is cool.

•  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.

1.  Clean the vacuum valve and the seal area of the cooling system cap.

2.  Verify that there is no damage or peeling on the seal area of the cooling system cap.

•  If there is any malfunction, replace the cooling system cap.

3.  Install the radiator cap tester to the cooling system cap.
