Procedures will vary depending on model and equipment fitted.
- Disconnect the battery negative cable(s).
- Drain the radiator.
- Remove any cables or lines clipped to the radiator or shrouds.
Remove the upper and lower heater hoses.
WARNINGMost cooling system hoses use "constant tension" hose clamps. When removing or installing, use a tool designed for servicing this type of clamp. The clamps are stamped with a letter or number on the tongue. If replacement is necessary, use only an OEM clamp with a matching ID.
CAUTIONAlways wear safety glasses when servicing constant tension clamps.
- If coolant overflow and windshield washer fluid bottles are fitted to the fan shroud, disconnect the lines and remove them. Pull straight up to remove the bottles from shroud.
- On 3.7L and 4.7 models, remove the upper fan shroud. Disconnect the electric fan wiring.
- On 2.5L models, disconnect the fan wiring, remove the fan and shroud hardware and remove the assembly.
- On other models, remove the fan shroud hardware and reposition the shroud towards the engine for access to the radiator.
- Label, then disconnect the automatic transmission lines if the fluid cooler is incorporated into the radiator. Plug the lines to prevent spillage. Be sure to note which line goes to which fitting..
- Check for rubber shields on the sides of the radiator. Remove them if fitted. These are normally secured with non-reusable plastic pins.
- Remove the radiator bolts (usually two at the top). Lift the radiator up and out of the vehicle, being careful that the cooling fins do not bang against anything. They are easily damaged.
Some vehicles may have an auxiliary automatic transmission fluid cooler which will come away with the radiator.
- Lower the radiator into place. There are two alignment pins at the bottom which fit into holes in the lower support.
- Tighten radiator mounting bolts to 17 ft. lbs. (23 Nm).
- The remainder of the procedure is the reverse of removal. Double-check the connection of all hoses and lines before adding fluids or operating the vehicle.
