Here is advice for finding the thermostat: * Follow the upper radiator hose from the radiator to the engine and there is a housing that houses the thermostat. Take it off and when you reinstall the thermostsat, make sure the spring goes toward the engine. * The thermostat is located on the motor block under the three bolt flang that the top rediator hose connects to. Remove the three 10MM bolts and the thermostat can be removed for replacement. * 1. Remove the air cleaner air duct from the throttle body and air cleaner. * 2. Follow the upper radiator hose to the engine to locate the thermostat housing. The housing is located at the front of the intake manifold. * 3. Loosen the hose clamp, then detach the hose from the fitting. This can be difficult. If it's stuck, grasp with a pair of adjustable pliers and twist to break the seal. Then pull it off. * 4. Remove the bolts and detach the housing cover. Be prepared some coolant may leak out as the gasket seal is broken. Remove the thermostat. * 5. Install the new o-ring onto the thermostat (no gasket is needed) and install the thermostat into the intake manifold with the spring side pointing toward the engine. * 6. Make sure the air release valve is in the up 12 o'clock position. Install housing cover and bolts. Reattach the hose fitting and tighten the hose clamp. Fill the cooling system with a 50/50 mix of coolant and water, and burp the system.

where is the thermostat and how do you replace it on a 1997 ford explorer? I don't know why this is listed as an answer. Its in the front top of the engine. in the middle, underneath that plastic cover that says SOHC. You'll probably need a universal joint on your extention to remove the 3 bolts holding it in place. (10 mm) One of the big hoses from the radiator connects directly to the plastic housing that surrounds it. Can't miss it.

The thermostat housing is located at the end of the lower radiator hose on these models.

There are two possible types of thermostat. On some models the thermostat housing is on the off side of the cylinder head below the fitting for the top radiator hose. In other models the thermostat is inside the top radiator hose and there is no housing for it on the cylinder head.
