Never remove the radiator cap while the engine is running or personal injury from scalding hot coolant or steam may result. If possible, wait until the engine has cooled to remove the radiator cap. If this is not possible, wrap a thick cloth around the radiator cap and turn it slowly to the first stop. Step back while the pressure is released from the cooling system. When it is certain all the pressure has been released, press down on the cap, still with the cloth, and turn and remove it.
Disconnect the negative battery cable.
Remove the radiator cap. Place a drain pan under the radiator, open the draincock and drain the coolant.
When draining the coolant, keep in mind that cats and dogs are attracted by the ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.
Remove the radiator support brace trim cover.
Disconnect the upper, lower and coolant reservoir hoses at the radiator.
Disconnect the fluid cooler lines at the radiator. On 1989-90 vehicles, tool T82L-9500-AH or equivalent, is required to disconnect the fluid cooler lines.
On 1991-98 vehicles, use a backup wrench to hold the radiator fitting while loosening the fluid cooler lines.
Remove the 2 upper fan shroud retaining bolts at the radiator support, lift the fan shroud sufficiently to disengage the lower retaining clips and lay the shroud back over the fan.
Remove the radiator upper support retaining bolts and remove the supports.
Lift the radiator from the vehicle.
If a new radiator is to be installed, transfer the petcock from the old radiator to the new one. Remove the fluid cooler line fittings from the old radiator and install them on the new one, using an oil resistant sealer.
Position the radiator assembly into the vehicle. Install the upper supports and the retaining bolts. Connect the fluid cooler lines.
Place the fan shroud into the clips on the lower radiator support and install the 2 upper shroud retaining bolts. Position the shroud to maintain approximately 1 in. (25mm) clearance between the fan blades and the shroud.
Connect the radiator hoses.
Install the radiator support brace trim cover.
Close the radiator petcock.
Fill the cooling system as explained in
General Information & Maintenance
Start the engine and bring to operating temperature.
Check for coolant and transmission fluid leaks. Check the coolant and transmission fluid levels.
