Locate the engine of your vehicle. It is usually underneath the hood of your car.
Identify the thermostat housing. It is usually a cylindrical or rectangular-shaped component located near the top of the engine. It will have hoses connected to it.
Remove the housing cover (if necessary). Some thermostat housings may have a cover. To remove the cover, you may need to pry it off gently using a flat-head screwdriver or other suitable tool.
Once you have removed the housing cover, you should see the thermostat located inside. It is usually a small, round, or cylindrical device with spring-loaded valve.

Please note that the exact location of the thermostat may vary slightly depending on the specific year and model of your vehicle. If you are unsure about the exact location of the thermostat, it is always best to consult the vehicle's repair manual or a qualified mechanic for assistance.
