Fig. Fig. 9 With the retainers removed and all lines/hoses disconnected, the radiator can be removed

  1. Disconnect the negative battery cable and drain the engine cooling system.
  2.  


CAUTION
When draining the coolant, keep in mind that cats and dogs are attracted by the ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

  1. As necessary, remove the fan, the upper fan shroud and/or the upper support. On vehicles equipped with a 1-piece shroud, if the fan is not to be removed, the shroud may be unbolted and then repositioned over the cooling fan for access to the radiator.
  2.  

If the fan is removed on vehicle equipped with a clutch type fan, be sure to keep it in an upright position to prevent the fluid from leaking.

  1. Disconnect upper and lower hoses.
  2.  
  3. Disconnect and plug the automatic transmission fluid cooler lines. All openings should be plugged to prevent system contamination or excessive fluid loss.
  4.  
  5. Lift radiator straight up and out of the vehicle.

To install:

  1. Carefully lower the radiator into the vehicle, making sure the lower cradles are properly located.
  2.
