Find and follow the upper radiator hose to where it connects to the auto thermostat housing. Don’t know what auto thermostat housing is? It’s where the opposite end of the upper radiator hose mounts to the engine. Drain the coolant from your radiator until it is below the thermostat. If you do not drain the coolant, it will cause your antifreeze to leak on the ground. That is very dangerous to animals as well as small children. So take precautions and drain coolant.

You need to loosen the clamp and remove the radiator hose from the auto thermostat housing. Make sure you have towels or rags near by to catch the antifreeze that leaks when removing the radiator hose from the auto thermostat housing. You need to remove the auto thermostat housing from the engine. You must first remove the bolts that hold this housing in place. Once you have removed them, you should be able to pull the housing directly out of the engine.

After removing the housing, you then can remove the old thermostat. Make sure you take a note of the alignment for future reference. Have a rag in hand and place it in the thermostat’s mounting hole so that no gasket material can enter the engine. After doing so, you can scrape the gasket from the housing and the engine.

Now that you have scraped the gasket, housing and engine, you can install your new thermostat. Make sure you position it the same way as the old one. This is important; failure to do so may cause this auto thermostat to be ineffective. Reinstall the housing and make sure the bolts are locked in. Use your torque wrench to the specifications of the manufacturer. Do not over tighten them. Reinstall the radiator hose to auto thermostat housing and clamp.

You now need to refill the radiator with coolant and start your car. Allow your car to heat up to normal temperature; while it is warming up, check for leaks. If you discover any, tighten any bolt as much as necessary to stop the leak. You can now stop your car, and allow it to rest completely. Check your coolant level, and add more if needed.
