Warning

•  If the engine 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 engine 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 engine cooling system cap and the sealed part.

2.  Inspect the engine cooling system cap for cracks or everted seal.

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

3.  Attach the engine cooling system cap to the radiator cap tester.
