What are the symptoms related to a bad thermostat?

The bad thermostat can cause two different sets of problems, depending on whether it's stuck open or stuck closed.

A thermostat that is stuck open can cause the engine to run colder than normal and turn on the check engine light. It may also cause poor fuel mileage and the heater to blow cool air.

A thermostat that is stuck closed will cause the vehicle to overheat. If a new thermostat doesn't resolve engine temperature problems, the cooling system needs to be checked for other issues.

Can I drive with a thermostat problem?

If the thermostat is stuck closed, no, you should stop driving immediately; if you don't, the engine can quickly overheat. An overheating engine should be shut off, and the vehicle should be towed. Overheating can severely damage the engine after only a few minutes.

If the thermostat is stuck open it may not cause engine failure, but you'll likely notice poor performance, an ineffective heater and bad fuel economy. It should be replaced at your earliest convenience.

How often do thermostats need to be replaced?

It all depends on the type of car you have and your driving conditions. The thermostat does not wear the same way a tire does, but will eventually fail and require replacement. Often, a new thermostat is recommended as preventative maintenance any time the cooling system is serviced, such as during radiator hose replacement or a timing belt service.
