### Tools Required

• | J 24460-01 EN-48501 Pressure Cap Adapter

• | J 24460-01 J-48501 Radiator Cap Pressure Adapter

• | J 24460-01 J-24460-01 Cooling System and Cap Pressure Tester

Caution: Under pressure, the temperature of the solution in the radiator can be considerably higher, without boiling. Removing the radiator cap while the engine is hot (pressure is high), will cause the solution to boil instantaneously, with explosive force. The solution will spew out over the engine, fenders, and the person removing the cap. Serious bodily injury may result. Flammable antifreeze, such as alcohol, is not recommended for use at any time. Flammable antifreeze could cause a serious fire.

Caution: In order to help avoid being burned, do not remove the radiator cap while the engine and the radiator are hot. Scalding fluid and steam can be blown out under pressure if the cap is removed too soon.

Caution: Refer to Radiator Cap Removal Caution in the Preface section.

Caution: Refer to Safety Glasses Caution in the Preface section.

Ensure engine is below 50 C before removing the coolant pressure cap.
