COOLING SYSTEM CAP INSPECTION


BME011215201201

Warning
• Never remove the radiator 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.
• After confirming all the pressure is released, press down on the cap using the cloth, turn it, and remove it.

1. Attach the cooling system cap to a radiator cap tester with the SST.

2. Apply pressure gradually.

3. Verify that the pressure becomes held within the specification.

Pressure
94-122 kPa {0.95-1.25 kgf/cm2, 13.6-17.7 psi}
• If the pressure is held for 10 s, the radiator cap is normal.
• If not within the specification, replace the cooling system cap.
