Radiator Removal
(only small differences between the v6 and 4 cylinder models)

- Disconnect the negative battery cable
- Drain and recycle the engine coolant
- If necessary for access to the radiator, remove the air intake duct assembly.
- On automatics, disconnect and plug the upper oil cooler line.
- Disconnect the engine strut brace at the radiator, loosen the engine side bolt and swing aside, if equipped.
- Mark and remove the hood latch from the radiator support, so it goes back in the way it came out.
- Detach the upper hose and coolant reserve tank hose from the radiator.
- Disconnect the light harness and fan wiring. Remove the electric cooling fan(s). On some models this may not be able to be removed unless the front end of the vehicle is raised and supported.
- Raise and safely support the vehicle on jack stands.
- Remove the engine cooling fan(s) if not yet done.
- If equipped, remove the splash panel below the radiator outlet hose. Detach the lower hose from the radiator.
- If equipped, disconnect and plug the lower oil cooler line.
- Carefully lower the vehicle.
- If equipped with air conditioning, remove the radiator to condenser bolts. - - Unbolt the refrigerant line clamp. Do Not disconnect the lines.
-Remove the mounting bolts and clamp, then the shroud (if equipped) and carefully lift the radiator out of the engine compartment. It works best if you start on the drivers side and work it out slowly trying not to damage anything.
