Radiator: Service and Repair

REMOVAL

NOTE: It is not necessary to discharge air conditioning system when removing the radiator.

1. Disconnect negative cable from remote jumper terminal.

WARNING: DO NOT REMOVE THE CYLINDER BLOCK PLUG OR THE RADIATOR DRAINCOCK WITH THE SYSTEM HOT AND UNDER PRESSURE BECAUSE SERIOUS BURNS FROM COOLANT CAN OCCUR.

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.

CAUTION: Avoid bending the condenser inlet tube. Care should be taken not to damage radiator or condenser cooling fins or water tubes during removal.








9. Remove the air conditioning condenser attaching screws located at the front of the radiator.
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.

CLEANING
Clean radiator fins are necessary for good heat transfer. The radiator and air conditioning fins should be cleaned when an accumulation of debris has occurred. With the engine cold, apply cold water and compressed air to the back (engine side) of the radiator to flush the radiator and/or A/C condenser of debris.

INSPECTION
1. Inspect the radiator tanks for cracks, broken or missing fittings also inspect the joint where the tanks seam up to the radiator core for signs of leakage and/or deteriorating seals.
2. Inspect radiator core for corroded, bent or missing cooling fins. Inspect the core for bent or damaged cooling tubes.

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 Nm (45 in. lbs.).
3. Install the radiator lower hose and clamp.
4. Install the transmission cooler line bracket and attaching fastener. Connect automatic transmission hoses and torque hose clamps to 3 Nm (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 Nm (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.
