RADIATOR

REMOVAL
1. Disconnect the negative battery cable.





2. Remove the radiator fan.
3. Drain the cooling system.
4. Remove the air cleaner inlet tubes.





5. Disconnect the upper radiator hose (1).





6. Disconnect the lower radiator hose (2).
7. Disconnect the coolant recovery reservoir hose (1).
8. Disconnect the transmission cooler line (3) located on the right side of the radiator (automatic transmission only).





9. Disconnect the transmission cooler line (1) located in the middle front of the vehicle (automatic transmission only).





Using a suitable tool, grasp the radiator hold down clamps (2) and pull up to remove the clamps from the mounting holes.





10. Remove the condenser retaining bolts (1) from the radiator support.

CLEANING
External cleaning of the radiator fins can be accomplished by applying cold water and compressed air to the back (engine side) of the radiator. This method will help to flush the radiator of any trapped debris.

INSPECTION
The radiator cooling fins should be checked for damage or deterioration. Inspect cooling fins to make sure they are not bent or crushed, these areas result in reduced heat exchange causing the cooling system to operate at higher temperatures. Inspect the plastic end tanks for cracks, damage, or leaks.

INSTALLATION
1. Carefully lower the radiator into the vehicle.





2. Connect the lower radiator hose (2).
3. Connect the coolant recovery reservoir hose (1).
