Removal & Installation


Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.

  1. Be sure the engine is cold before removing the radiator.
  3. Disconnect or remove:

    Intake duct
    Fan cowl
    Drain coolant
    Coolant hoses
    If equipped with an automatic transmission, remove tubing to heat exchanger core in radiator
    Locking screw (illustrated with an arrow)
    Bracket bolt (1) holding radiator
    Remove radiator up and out
