    Disconnect the negative battery cable at battery.

    Drain coolant from radiator.

    Do not attempt to remove fan/viscous fan drive assembly from vehicle at this time.

    Remove the front grill.

    Remove two radiator mounting bolts.

    Disconnect both transmission cooler lines from radiator.

    Disconnect electric fan connector, then disconnect connector harness from shroud.

    Disconnect the radiator upper and lower hoses.

    Disconnect the overflow hose from radiator.

    Remove the air inlet duct at the grill.

    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 BEFORE HANDLING ANY AIR CONDITIONING COMPONENT.

    If equipped with an auxiliary automatic transmission oil cooler, use caution when removing radiator. The oil cooler lines are routed through a rubber air seal on the right side of radiator. Do not cut or tear this seal.

    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).


    CAUTION: Before installing the radiator or A/C condenser, be sure the radiator-to-body and radiator-to A/C condenser rubber air seals are properly fastened to their original positions. 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.

    Equipped with air conditioning: Gently lower the radiator into the vehicle. Guide the two radiator alignment dowels through the holes in the rubber air seals first and then through the A/C support brackets. Continue to guide the alignment dowels into the rubber grommets located in lower radiator crossmember. The holes in the L-shaped brackets (located on bottom of A/C condenser) must be positioned between bottom of rubber air seals and top of rubber grommets.

    Connect the radiator upper and lower hoses and hose clamps to radiator. CAUTION: The tangs on the hose clamps must be positioned straight down.

    Install coolant reserve/overflow tank hose at radiator.

    Connect both transmission cooler lines at the radiator.

    Install both radiator mounting bolts.

    Install air inlet duct at grill.

    Attach electric fan harness to shroud, then connect harness to connector.

    Install the grill.

    Install the fan/viscous fan drive assembly to the water pump.

    Rotate the fan blades (by hand) and check for interference at fan shroud.

    Be sure of at least 25 mm (1.0 in.) between tips of fan blades and fan shroud.

    Fill cooling system.

    Connect battery cable at battery.

    Start and warm engine. Check for leaks.
