How do you change the thermostat on a 1994 Ford Ranger XLT 2.4l?

Answer 1

Do this once engine is cool. Locate the thermostat housing on the front of the motor above the water pump. Two small bolts (probably 10mm) should be there; the one on the right is probably right beside the front engine cover. Remember to drain your coolant down first and then remove the thermostat housing. Once off, remove the old stat and clean the gasket area with a gasket scraper. Then replace the new thermostat with "copper pellet" side facing in towards the engine. Apply some form of gasket sealer to the new thermostat housing gasket (both sides) and tighten up the bolts. Refill with coolant and that's it.
