CAUTION
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 quantity. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.

  1. Drain the coolant, then disconnect the upper and lower hoses.
  2.  
  3. Disconnect and plug the ATF cooler lines, if equipped with automatic transmission.
  4.  
  5. Remove the upper fan shield (6-cylinder) or upper shroud bracket (V8).
  6.  

Remove the radiator hold-down bolts and lift the radiator and shroud assembly from the car.

  1. To install, reverse the removal procedure, making sure that the automatic transmission fluid level is correct. Tighten the hold-down bolts to 12 ft. lbs.
