How do I replace a car thermostat?
assistant
1. To replace a car thermostat, start by locating the thermostat housing. On most vehicles, this is located near the top of the engine on the side closest to the firewall.
2. Next, disconnect the negative battery cable to prevent any electrical shock.
3. Now, remove the upper radiator hose from the thermostat housing. Make sure to loosen the retaining clamp or bolt to prevent any leaking.
4. After that, you can remove the two bolts that are securing the thermostat housing to the engine.
5. Once the housing is free, carefully remove the thermostat, gasket, O-ring, and springs.
6. Now, you can install the thermostat in the housing with the jiggle spring or piston facing up or toward the engine.
7. Once the thermostat is in place, put the remaining pieces back together and fasten the thermostat housing back onto the engine.
8. Finally, secure the upper radiator hose, reattach the negative battery cable, and start your engine to test the new thermostat.
