    Locate the radiator.

    There are 2 large hoses that connect to the radiator.

    The lower hose ( the large hose on the bottom ) goes directly to the water pump.

    The upper hose ( the large hose on the top ) goes directly to the thermostat housing.

    Inside of the thermostat housing is the thermostat.

    The thermostat housing is secured by 2 bolts.

    If you plan on replacing the thermostat,, then may i make 2 suggestions:

    A. take car in to the shop for this service.

    B. Post your next question on the step by step procedure to Mr. Shift Right,,here at edmunds dot com he is the expert on thermostat replacement.

    He will be more than glad to walk you through this procedure,,additionally he can provide you with multiple sources listing supplies,,tools,,equipment,,and diagrams.

    Hi grouchman Hi Tony:

    Okay, here's what I have:

    WARNING: SCALDING HOT COOLANT, WATER OR STEAM
    NEVER remove the pressure relief cap under any conditions while the engine is operating. Failure to follow these instruction could result in DAMAGE to the cooling system or engine AND/OR personal injury. To avoid having scalding hot coolant or steam blow out of the cooling system or reservoir, use extreme care when removing the pressure relief cap from a hot cooling system or reservoir.

    1. Wait until the engine has cooled.
    2. Wrap a thick cloth around the pressure relief cap and turn it slowly (until the pressure begins to release.
    3. Step back while the pressure is released from the cooling system.
    4. When you are certain all the pressure has been released, (still with a cloth) turn and remove pressure relief cap .

    REMOVAL


    1. Drain the engine cooling system so that the engine coolant level is below the water thermostat .
    2. Raise vehicle on hoist. See General Information.
    3. Disconnect the lower radiator hose and degas bottle hose from the water inlet connection.
    4. Remove the two water inlet connection retaining bolts. Remove the water inlet connection.
    5. Remove the O-ring seal and water thermostat from the water thermostat housing. Inspect O-ring for damage and replace if necessary.
    6. If required, remove water bypass hose from water thermostat housing and remove water thermostat housing retaining bolts, water thermostat housing and O-ring from oil filter adapter . Inspect O-ring for damage and replace if necessary.

    INSTALLATION

    1. Install the water thermostat, O-rings, water thermostat housing (if removed) and water inlet connection as illustrated.
    2. Install and alternately tighten the retaining bolts. Tighten bolts to 20-30 Nm (15-22 ft. lbs.).
    3. If removed, connect the water bypass hose to the water thermostat housing.
    4. Connect the lower radiator hose and degas bottle hose to the water inlet connection.
    5. Lower vehicle.
    6. Fill the coolant with Ford Premium Cooling System Fluid E2FZ-19549-AA or-B (in Oregon, F5FZ-19549-CC, in Canada, Motorcraft CXC-8-B) or equivalent that meets Ford specification ESE-M97B44-A in a 50/50 mixture with water.
    7. Start the engine and check all hoses and connections for leaks. Allow the engine to warm up so that the water thermostat opens.
    8. Stop the engine. Top off degas bottle as required to maintain minimum cold fill level.
