COOLING SYSTEM CAP INSPECTION

Warning
• Never remove the cooling system cap while the engine is running, or when the engine and
radiator are hot. Scalding 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're sure all the pressure is gone, press down on the cap using the cloth, turn it, and
remove it.
1. Clean the cooling system cap and the sealed part.
2. Inspect the crack or turn over on the sealed part of the cooling system cap.
• If there is malfunction, replace the cooling system cap.
3. Attach the cooling system cap to the radiator cap tester.
