WARNING: Do not remove the cylinder block drain plugs or loosen the radiator draincock with the system hot and under pressure. Serious burns from coolant can occur. Refer to DRAINING COOLING SYSTEM .

Do not waste reusable coolant. If the solution is clean, drain the coolant into a clean container for reuse.

WARNING: Constant tension hose clamps are used on most cooling system hoses. When removing or installing, use only tools designed for servicing this type of clamp. Always wear safety glasses when servicing constant tension clamps.

CAUTION: When removing the radiator or A/C condenser for any reason, note the location of all radiator-to-body and radiator-to-A/C condenser rubber air seals. These are used at the top, bottom and sides of the radiator and A/C condenser. To prevent overheating, these seals must be installed to their original positions.

Disconnect the negative battery cable at battery.
Drain coolant from radiator. Refer to DRAINING COOLING SYSTEM .
Remove the front grille. Refer to REMOVAL .
Remove two radiator mounting bolts.
Disconnect both transmission cooler lines from radiator.
Disconnect electrical connector for the fan control solenoid.
Disconnect the power steering cooler line from cooler and filter.
Disconnect the radiator upper and lower hoses.
Disconnect the overflow hose from radiator.

Remove the air inlet duct at the grille.

4 - RADIATOR LOWER CROSSMEMBER

The lower part of radiator is equipped with two alignment dowel pins. They are located on the bottom of radiator tank and fit into rubber grommets. These rubber grommets are pressed into the radiator lower crossmember.
WARNING: The air conditioning system (if equipped) is under a constant pressure even with the engine off. Refer to refrigerant WARNINGS in HVAC - SERVICE INFORMATION article before handling any air conditioning component.

NOTE: The radiator and radiator cooling fan can be removed as an assembly. It is not necessary to remove the cooling fan before removing or installing the radiator.
Disconnect the two high pressure fluid lines at the hydraulic fan drive.
Disconnect the low pressure return hose at the hydraulic fan drive.
Gently lift up and remove radiator from vehicle. Be careful not to scrape the radiator fins against any other component. Also be careful not to disturb the air conditioning condenser (if equipped).
