Removal and Installation

REMOVAL

WARNING:

Do not remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure 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.

CAUTION:

Perform these steps after the coolant temperature has cooled sufficiently.

NOTE:

When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spilling.

  1. Remove the engine under cover. Refer to EXT-31, "ENGINE UNDER COVER : Removal and Installation".
  2. Drain engine coolant from radiator. Refer to CO-12, "Changing Engine Coolant".
  3. Remove water hose and heater thermostat assembly.
