REMOVAL & INSTALLATION
See Figures 1 through 10
- Disconnect the negative battery cable for safety. On vehicles with an electric cooling fan, the fan could come on at any time.
Before draining the cooling system is a good time to decide if it is time to replace your coolant. If not, the drain pan must be clean and free of oil or other contaminants so that the coolant can be reused. For more information, please refer to the Fluids and Lubricants information in General Information & Maintenance in this repair guide.
- Make sure the engine is cool, then remove the radiator cap and drain the engine cooling system into a suitable container.
- Disconnect the upper, lower and coolant reservoir hoses at the radiator.
- If equipped with an automatic transmission, disconnect the fluid cooler lines at the radiator. Depending on the year and model, your vehicle may used threaded fittings (on which a backup wrench should be used to prevent damage to the radiator) or quick-connect coupling fittings which require a special release tool.
On vehicles equipped with automatic transmissions and quick connect couplings, disconnect the fluid cooler lines at the radiator using oil cooler line quick connect coupling tool T82L-9500-AH or equivalent.
- On the 2.3L engine, remove the electric cooling fan/shroud assembly.
- On the 5.0L engine, remove the two 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.
- On some models the coolant overflow bottle is bolted to the radiator. If so, you can ease radiator removal by unbolting and removing the overflow bottle.
- 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. If equipped with automatic transmission and quick connect couplings, transfer the fluid cooler line fittings from the old radiator. Use a pipe sealant with Teflon® or equivalent oil resistant sealer.
- Position the radiator assembly into the vehicle. Install the upper supports and the retaining bolts. If equipped with automatic transmission, connect the fluid cooler lines.
- If removed, install the coolant overflow bottle.
- On the 2.3L engine, install the electric cooling fan/shroud assembly.
- On the 5.0L engine, place the fan shroud into the clips on the lower radiator support and install the two upper shroud retaining bolts. Position the shroud to maintain a minimum of 0.38 in. (9.7mm) clearance between the fan blades and the shroud.
- Connect the radiator hoses. Close the radiator petcock.
- Connect the negative battery cable, then fill and bleed the cooling system.
- Run the engine to normal operating temperature. Check for coolant and transmission fluid leaks.
- Shut the engine OFF , then check the coolant and transmission fluid levels.
