Question about 1983 Ford Fairmont
Most thermostats are located under the waterneck that connects across from the top of your radiator via a hose that brings water from the engine to the radiator to be cooled. Some cars have the thermostat in the radiator under the radiator cap but this is rare and an Oldsmobile 80's style. Make sure the engine is cool and drain the coolant using the butterfly valve at the bottom of the radiator. Catch the coolant in a bucket, if clean it can be reused once you are done. You dont have to completely drain the system, maybe a 1/2 gallon or so should do. Now loosen the hose that comes from the top of the radiator to the motor. Remove the hose (expect some coolant to be in the area). Now you should have 2 or 3 bolts holding down your waterneck. Loosen and remove them, lift the waterneck and your thermostat is under it. You will need a new gasket and a VERY thin film of gasket sealer, high temp might be a good choice. All, including the Stat are available at auto parts stores. Reinstall in reverse order and refill the radiator. Start the motor bring it up to temp. Good luck and remember-NEVER OPEN A RADIATOR CAP ON A HOT MOTOR!
