How to change a thermostat


Hi.

  1. Locate the thermostat housing. The housing can be found following the radiator hose toward the engine. The housing is located on the engine.
  2. Remove the three screws that hold the thermostat housing.
  3. Replace the thermostat.

Note. The thermostat spring goes toward the engine, the other side toward the radiator.

1999 Pontiac Bonneville 3800 engine. How do I replace the water thermostat?


Follow the top radiator hose down. It will connect to the engine. At the point that it connects to the engine is where the thermostat is located. This thermostat cover will have two bolts. Some of the 3800 engines have a temp sensor in the housing. You will not have to mess with the sensor. The housing will have 2 bolts that hold it on. Remove the two bolts and the housing will lift off. And the thermostat will be under the housing. Replace the thermostat. And reinstall the housing.

Trying to locate where the thermostat is on a 1991 Honda Accord LX


The thermostat is usually located at the lower radiator hose inlet to the engine, that is where you will find the thermostat housing to remove the thermostat.

Remember that the spring end of the thermostat should always go towards the engine, and not towards the radiator hose.

How do I install a new thermostat?


Explorer Thermostat LocationHere is advice for finding the thermostat:

  • Follow the upper radiator hose from the radiator to the engine and there is a housing that houses the thermostat. Take it off and when you reinstall the thermostsat, make sure the spring goes toward the engine.

  • The thermostat is located on the motor block under the three bolt flang that the top rediator hose connects to. Remove the three 10MM bolts and the thermostat can be removed for replacement.

How to Change an Explorer Thermostat
  • 1. Remove the air cleaner air duct from the throttle body and air cleaner.
  • 2. Follow the upper radiator hose to the engine to locate the thermostat housing. The housing is located at the front of the intake manifold.
  • 3. Loosen the hose clamp, then detach the hose from the fitting. This can be difficult. If it's stuck, grasp with a pair of adjustable pliers and twist to break the seal. Then pull it off.
  • 4. Remove the bolts and detach the housing cover. Be prepared some coolant may leak out as the gasket seal is broken. Remove the thermostat.
  • 5. Install the new o-ring onto the thermostat (no gasket is needed) and install the thermostat into the intake manifold with the spring side pointing toward the engine.
  • 6. Make sure the air release valve is in the up 12 o'clock position. Install housing cover and bolts. Reattach the hose fitting and tighten the hose clamp. Fill the cooling system with a 50/50 mix of coolant and water, and burp the system.
