How do you change the thermostat on 1989 ford Bronco Eddie Bauer full size?

Answer 1

The top radiator hose feeds into a round metal thing on top of the engine. Drain the radiator, take off the top hose by removing the hose clamps, inspect the hose for damage and cracks, the round metal thing (thermostat housing) can be taken off by removing the two bolts that hold it in. take out the old thermostat and replace it with the new one. It may have a rubber gasket so double check. Put it all back together and refill the radiator with 50/50 antifreeze and water. Run it til the level drops and top it off again. Check for leaks.
