REMOVAL & INSTALLATION



See Figures 1, 2, 3, 4, 5, 6, 7 and 8

On some models, it may be necessary to remove the grille before removing the radiator. The cooling system can be drained by opening the drain cock at the bottom of the radiator or by removing the lower radiator hose. Be careful not to damage the fins or core tubes when removing and installing the radiator. NEVER OPEN THE RADIATOR CAP WHEN HOT!

  1. Drain the engine coolant into a clean container. On fuel injected models, remove the air cleaner inlet pipe.
  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. Disconnect the upper and lower radiator hoses and the coolant reserve tank hose.
  2.  
  3. Disconnect the automatic transmission oil cooler lines if so equipped. Plug the lines to keep dirt from entering them.
  4.  
  5. If the radiator has a fan shroud, unbolt the shroud and move it back. Hang it over the fan.
  6.  
  7. Remove the radiator mounting bolts and the radiator.
  8.  

To install:
  1. Install the radiator in the vehicle and tighten the mounting bolts evenly.
  2.  
  3. If equipped with an automatic transmission, connect the cooling lines at the radiator.
  4.  
  5. Connect the upper and lower hoses, along with the coolant reserve tank hose.
  6.  
  7. Refill the cooling system (refer to General Information & Maintenance ) and automatic transmission if necessary, operate the engine until warm and then check the coolant level. Check also for any leaks.
