01Step 1: Gather the necessary tools and materials

  • Before starting the replacement process, make sure you have the following tools and materials:
  • - New thermostat housing
  • - New thermostat gasket
  • - Wrench set
  • - Screwdriver set
  • - Coolant drain pan
  • - Funnel
  • - Coolant
  • - Rag or towel

02Step 2: Prepare the car

  • To begin, park your car on a flat and level surface.
  • Allow the engine to cool down completely before starting any work to avoid burns from hot coolant.
  • Make sure you have access to the car's engine bay and can easily reach the thermostat housing.

03Step 3: Drain the coolant

  • Locate the coolant drain plug or valve on the radiator and place a coolant drain pan beneath it.
  • Carefully open the drain plug/valve to allow the coolant to flow into the pan.
  • Dispose of the old coolant properly according to local regulations.

04Step 4: Remove the old thermostat housing

  • Locate the thermostat housing on the engine. It is usually connected to the upper radiator hose.
  • Use the appropriate wrench or socket to remove the bolts securing the housing in place.
  • Gently separate the housing from the engine and remove the old thermostat and gasket.

05Step 5: Install the new thermostat housing

  • Clean the mating surfaces of the engine and the new thermostat housing to ensure a proper seal.
  • Place the new thermostat and gasket in position, aligning the bolt holes with those on the engine.
  • Secure the housing in place by tightening the bolts according to the manufacturer's specifications.

06Step 6: Refill the coolant

  • Using a funnel, carefully pour the recommended amount of coolant into the radiator.
  • Check the car's owner manual or the coolant container for the appropriate coolant mixture and level.
  • Close any coolant drain plugs/valves and ensure the radiator cap is tightly sealed.

07Step 7: Test for leaks and functionality

  • Start the car and let it idle for a few minutes to allow the engine to warm up.
  • Monitor the temperature gauge to ensure it stays within the normal operating range.
  • Inspect the thermostat housing and surrounding areas for any signs of leaks.

Conclusion

By following these steps, you can successfully change a car thermostat housing. Remember to exercise caution and ensure proper coolant levels and functionality before taking the car out on the road.
