  1. Disconnect negative cable from remote jumper terminal.
  2. Drain cooling system.
  3. Remove radiator upper crossmember.
  4. Remove upper and lower coolant hoses from the radiator.
  5. Disconnect transmission hoses from cooler and plug.
  6. Disconnect engine oil cooler lines (if equipped).
  7. Disconnect the radiator fan electrical connector.
  8. Remove radiator fan. 1 - ELECTRICAL CONNECTOR 2 - FASTENERS 3- CLIPS
  9. Remove the air conditioning condenser attaching screws located at the front of the radiator. see scheme 4or see scheme 5. 1 - TRANS COOLER LINE BRACKET SCREW 2 - SCREW - CONDENSER TO RADIATOR 3- TRANS COOLER 4- SCREWS 1 - TRANSMISSION OIL COOLER LINE MOUNTING BRACKET 2 - A/C CONDENSER TO RADIATOR MOUNTING SCREWS
  10. Remove fastener attaching transmission cooler line bracket to left side of radiator.
  11. Lift condenser upward enough to disengage upper mounting clips. Allow condenser to rest on lower radiator crossmember. It is not necessary to discharge the air conditioning system.
  12. Radiator can now be lifted from engine compartment. Care should be taken not to damage radiator cooling fins or water tubes during removal.

INSTALLATION

  1. Position radiator into engine compartment. Seat the radiator assembly lower rubber isolators into the mounting holes in radiator lower support.
  2. Attach air conditioning condenser to mounting clips on radiator. Install mounting screws and tighten to 5 N.m (45 in. lbs.).
  3. Install the radiator lower hose and clamp.
  4. Install the transmission cooler line bracket and attaching fastener. see scheme 4or see scheme 5. Connect transmission hoses and tighten hose clamps to 3 N.m (28 in. lbs.).
  5. Install the radiator fan.
  6. Connect radiator fan motor electrical connector.
  7. Connect engine oil cooler lines (if equipped). Torque lines to 18 N.m (160 in. lbs.).
  8. Install the radiator upper hose. Align hose so it does not interfere with the accessory drive belt or engine. Position hose clamp so it will not interfere with the hood.
  9. Install the radiator upper support crossmember.
  10. Connect negative cable to remote jumper terminal.
  11. Fill cooling system with coolant.
  12. Operate engine until it reaches normal operating temperature. Check cooling system and automatic transmission for correct fluid levels.
