REMOVAL & INSTALLATION



See Figures 1 through 8

  1. Drain the cooling system.
  2.  


CAUTION
When draining 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. Unfasten the clamps, then remove the radiator upper and lower hoses. If equipped with an automatic transmission, remove the oil cooler lines.
  2.  
  3. If necessary, detach the hood lock cable and remove the hood lock from the radiator upper support.
  4.  

It may be necessary to remove the grille in order to gain access to the hood lock/radiator support assembly

  1. Remove the fan shroud and electric cooling fan, if so equipped.
  2.  
  3. On models equipped with a coolant recovery system, disconnect the hose and remove the thermal expansion tank from its bracket.
  4.  
  5. Unbolt and remove the radiator upper support or upper radiator mounting clamps, as necessary.
  6.  
  7. Unfasten the bolts and remove the radiator.
  8.  


CAUTION
Use care not to damage the radiator fins on the cooling fan!

  1. Installation is performed in the reverse order of removal. Remember to check the transmission fluid level on cars with automatic transmissions.
  2.  
  3. Fill the radiator to the specified level.
  4.  
  5. Certain models are equipped with an electric, rather than a belt-driven, cooling fan. Using a radiator-mounted thermoswitch, the fan operates when the coolant temperatures reach 203°F and stops when it lowers to 190°F. It is attached to the radiator by the four radiator retaining bolts. Radiator removal is the same for this engine as all others, except for disconnecting the wiring harness and thermoswitch connector.
