Car Thermostat Replacement Service

What is an engine cooling system thermostat and how does it work?

The car's engine cooling system thermostat is a small valve within a cooling system passageway that opens and closes in response to the temperature of the circulating engine coolant. When your car is first started and the coolant is cold, the valve in the thermostat will be in the closed position, circulating the coolant flow only within the engine instead of flowing to the radiator, which allows the engine to warm up fast, promoting fuel efficiency, low emissions, and reduced engine deposits. Once the engine coolant reaches the design temperature, usually around 195 degrees, the valve will open and close as you drive in order to maintain a coolant temperature typically between 195 to 225 degrees Fahrenheit.

Thermostat

When to consider replacing the engine cooling system thermostat:

  • Engine overheats. A thermostat with the valve stuck closed is a common cause of engine overheating. However, since there are other causes of overheating, a mechanic will thoroughly inspect the cooling system prior to condemning the thermostat. Since it is usually not known how badly the engine overheated, the mechanic will also try to determine if there is evidence that the cylinder head gasket was blown. If so, it would be repaired prior to replacing the thermostat.
  • Temperature gauge reads too low or too high. Thermostats can get sticky, causing the engine temperature to stray from the optimal range. Your dash-mounted temperature gauge will notify you of this malfunction.
  • Cooling system repairs. All thermostats eventually fail. Therefore, if the cooling system is already open for major repairs, such as water pump or radiator replacement, it is recommended to install a new thermostat simply as insurance against future breakdown.

How do mechanics replace the engine cooling system thermostat?

  • Once the engine is completely cold, the radiator cap is loosened and enough coolant is drained from the radiator so the coolant level is below the thermostat housing.
  • The thermostat housing is removed and the thermostat and gasket are extracted. Note that some cars have more than one cooling system thermostat and both might need replacement.
  • All mounting surfaces on the thermostat housing are cleaned of old gasket material. A new gasket is applied and the thermostat is re-installed in the correct orientation and with the temperature sensing cylinder facing downward towards the engine.
  • The thermostat housing bolts are tightened to original equipment manufacturer (OEM) specifications using a calibrated inch-pound torque wrench.
  • The cooling system is refilled with the appropriate coolant type and the system is fully bled of all air.
  • The car engine is run until the normal operating temperature is reached, and while taking precautions with the hot coolant, the coolant level is rechecked while confirming there is flow through the radiator — either visually or with an infrared temperature gun. This will confirm the thermostat is open. Finally, the engine is checked for leaks.

Is it safe to drive with an engine cooling system thermostat problem?

No. If it has been determined that there is a thermostat problem, it should be repaired right away. Failure to do so can cause substantial and costly damage to the engine.

When replacing the engine cooling system thermostat keep in mind:

  • Engine overheating due to causes other than a faulty thermostat, will themselves damage a thermostat. Therefore, always replace the thermostat if the engine overheats, even if the thermostat was not the initial cause of the overheating.
  • The thermostat should be replaced anytime you have major work done on the coolant system. It is convenient and costs little during such repairs and insurance against future breakdown.
  • OEM thermostats are the best ones to use and you can request your mechanic to install only the OEM thermostat. Dealer supplied, OEM thermostats are sometimes more costly but are generally higher quality and specifically engineered for your car.

It's taken me a while to do this, so I apologize Theodore. This was my first time using YourMechanic, so I was a bit skeptical especially since my quote for this work was just over $100 less than 2 other shops and at least an hour less of work time. Aside from the huge convenience of YourMechanic saving me the hassle of planning the time to take my car to a shop, I ultimately decided to use th for the savings. After the work Theodore did on my car I have nothing but great things to say about him and YourMechanic, in fact I've been recommending them to everyone I know. Theodore was right on time, very professional and very courteous. Aside from the great job he did fixing my car, which is still working a month later without any issues on what he repaired, I was most impressed with his patience with me. Every time I have work done on my car I like to know as much as I can about what is wrong, how that part/system works usually, basically pick the mechanics' brain both for my understanding and to try to measure if I can trust them (yes, even if I myself might not know what they're talking about). Theodore was super nice, patient with my questions and with his answers, and this is huge in my opinion. I'm always looking out for a shop I can trust for work on my cars and now I know moving forward that I'll be using YourMechanic in the future, and they have Theodore to thank for that.

Awesome mechanic. Explained everything that was wrong, how he fixed it, and what everything did. Showed up early, and did extra to make sure that the job would be finished and correct. I will be recommending Pete to my friends and family every time they use Your Mechanic.

Jonathan just finished the needed services on my car, this is our first time using your mobile service & I am very excited about the convenience factor. Jonathan was a little quiet at first, I'm the type of person that needs to understand what is being done, but he did explain everything & turned out to be friendly, professional, & knowledgeable. I haven't tested the car yet, but have already referred a few friends & neighbors. I will give higher score after I test the car, & will schedule appointments with him as needed & as I can afford. Thank you
