Good To Know

Q: How do I know if my thermostat needs replacing? A: Common signs include slow warm-up, overheating, or erratic temperature readings on your gauge. A thermostat stuck open or closed is the usual cause.

Q: Does this thermostat come with a gasket? A: Check the listing contents for included hardware, since gaskets are sometimes sold separately. Reusing a worn gasket is not advised.
