Safety Precautions
Before you begin, be sure to take the following safety precautions:

Step-by-Step Instructions
1. Locate the Thermostat
The thermostat is typically located in a housing on the engine block. Consult your vehicle’s service manual for the exact location.
2. Drain the Coolant
Place the drain pan under the radiator and open the drain plug. Allow the coolant to drain until the level drops below the thermostat housing.
3. Remove the Thermostat Housing
Use the socket wrench to remove the bolts that hold the thermostat housing in place. Carefully lift off the housing and gasket.
4. Remove the Old Thermostat
Use the screwdriver or pliers to remove the old thermostat from the housing. Be careful not to damage the gasket.
5. Install the New Thermostat
Insert the new thermostat into the housing, making sure that the gasket is properly seated.
6. Reassemble the Thermostat Housing
Place the gasket on the thermostat housing and carefully tighten the bolts.
7. Refill the Coolant
Pour new coolant into the radiator until it reaches the “full” mark.
8. Start the Engine
Start the engine and let it run for a few minutes. Check for any leaks and adjust coolant level as needed.
Troubleshooting
If you encounter any problems while changing your car thermostat, here are some troubleshooting tips:
- If you can’t find the thermostat, consult your vehicle’s service manual.
