WARNING:
Do not remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure engine coolant escaping from the radiator. Wrap a thick cloth around the cap. Slowly push down and turn it a quarter turn to allow built-up pressure to escape. Carefully remove the cap by pushing it down and turning it all the way.
NOTE:
When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spilling.
Removal and Installation
REMOVAL
- Disconnect the negative battery terminal. Refer to PG-52, "Removal and Installation".
- Remove fan shroud and motor assembly. Refer to CO-17, "Removal and Installation".
- Remove radiator cap, open radiator drain plug and drain engine coolant from radiator. Refer to CO-12, "Changing Engine Coolant".
CAUTION:
