Good To Know

Q: What happens if I run the wrong thermostat temperature? A: A thermostat that opens too late can cause overheating, while one that opens too early keeps the engine cold and hurts performance and fuel economy.

Q: Should I replace the thermostat gasket or seal at the same time? A: Yes, replacing the seal or O-ring during installation is good practice to prevent coolant leaks at the housing.
