How do you replace a thermostat for a Jeep Wrangler?

Answer 1

Very easy job. Visit your auto-parts store first, get a thermostat ( they can tell you what temperature, etc..) make sure you purchase a gasket, and sealer that's sensor safe for newer vehicles.don't forget to pick up a gallon of coolant. You are gonna lose some. Ok trace the top hose from the radiator to the top of the engine. This is where the

thermostat lives, should be two bolts on the

housing, after you disconnect the hose from the top of the engine,remove the two bolts. You may have to carefully pry or tap the housing to break the seal. Remove thermostat noting orientation. Clean all mating surfaces with a plastic scraper of some sort, place new thermostat inside. use your gasket sealer on top of manifold and the

thermostat housing. Stick gasket onto maniflod lining up the bolt holes, place housing onto manifold replace bolts and torque to specs. It's probably aluminum so this step is a must unless you've done several. Replace hose. Fill with coolant, get up to operating temperature, purge air if it's a import, if it's a domestic (USA) it does it it's self. Check coolant again after it sits awhile. That's it.
