What to do after replacing thermostat in car

After replacing the thermostat in your car, it’s important to properly bleed the coolant system to remove any air pockets that may have formed during the installation. To do this, you’ll need to locate the bleeder valve on the engine and use a wrench to open it. Then, with the engine running, slowly open the radiator cap and allow the coolant to flow through the valve until a steady stream of coolant is flowing out. Make sure to keep an eye on the coolant level in the radiator and refill it as necessary to avoid overheating the engine. Once you’ve bled the system and confirmed that there are no air pockets, you can close the bleeder valve and the radiator cap, and your thermostat replacement should be complete.
