On some models, it may be necessary to remove the front grille to remove the radiator. The cooling system can be drained from opening the drain cock at the bottom of the radiator or by removing the bottom hose at the radiator. Be careful not to damage the fins or core tubes when removing and installing the radiator to the vehicle. 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 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. Cap the lines to keep dirt out of them.
  4.  
  5. If the fan has a shroud, unbolt the shroud and move it back, hanging it over the fan.
  6.  
  7. Remove the radiator mounting bolts and the radiator.
  8.  
  9. Install the radiator in the vehicle and tighten the mounting bolts evenly.
  10.  
  11. If equipped with an automatic transmission, connect the cooling lines at the radiator.
  12.  
  13. Connect the upper and lower hoses and the coolant reserve tank hose.
  14.  
  15. Refill the cooling system (refer to ) and automatic transmission if necessary, operate the engine until warm and then check the coolant level and for leaks.
