Removal Procedure
Warning: With a pressurized cooling system, the coolant temperature in the radiator can be considerably higher than the

high pressure, causes the solution to boil instantaneously with explosive force. This will cause the solution to spew out over
the engine, the fenders, and the person removing the cap. Serious bodily injury may result.
