Removal and Installation

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 radiator cap. Slowly turn it a quarter turn to allow built-up pressure to escape. Carefully remove the radiator cap by turning it all the way.

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

  • When radiator is cleaned on-vehicle, remove surrounding parts in order to access the radiator core. Tape the harness and electrical connectors to prevent water from entering.
  1. Spray water to the back side of the radiator core using a side to side motion from the top down.
  2. Stop spraying when debris no longer flows from radiator core.
  3. Blow air into the back side of radiator core using a side to side motion from the top down.
  • Use compressed air lower than 490 kPa (5 kg/cm2, 71 psi) and keep distance more than 30 cm (11.8 in).
  1. Continue to blow air until no water sprays out.
  2. Inspect radiator for leaks as follows:
