We’ve already discussed the importance of your cooling system and the role it plays in keeping your engine cool and your interior warm. And you know an engine that’s running too hot can cause major and expensive damage
But did you know that running too cool can mean wasting fuel? It’s true, and it’s the job of the thermostat to keep the engine running at its most efficient temperature.
It does so by being placed between the radiator and the engine, where it monitors your engine for the optimal running temperature. When it senses things are getting a bit heated, a special heat sensitive wax expands, causing a valve to open. This allows the coolant to flow from the engine to the radiator, cooling things back to an acceptable level.
If things are a bit too cool, the wax contracts and the spring loaded valve closes to keep your engine warm enough to run efficiently.
While there isn’t much maintenance you can do for the thermostat, you can help prolong its life by ensuring your coolant is kept at the proper ratio and changed on schedule. The erosion inhibitors in your coolant will help to ensure your thermostat doesn’t wear out before its time.
Something to keep in mind is your thermostat will generally wear out faster than your hoses. This means it’s a good idea to change your thermostat when your hoses begin to go bad. Taking care of these things at the same time can mean a savings in labor since your auto repair shop tech is already in there anyway.
You may also consider changing it any time you do a radiator flush. If you are not sure what is right for your car, give Leslie a call. He’ll be happy to talk with you about what’s best for your specific car.
