The entire cooling system should be inspected and tested when the thermostat is replaced.

A high-quality OEM thermostat should be used. Poor quality thermostats may not function properly and can cause damage to the engine or components of the emission system.

A thermostat that is stuck closed will cause the vehicle to overheat.

If the new thermostat does not immediately resolve engine temperature problems, the cooling system needs to be checked for other issues.

A thermostat that is stuck open can cause the engine to run colder than normal and set the Check Engine Light. It may also cause poor fuel mileage and the heater to blow cool air.
