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.

Honda Civic - Thermostat - West Chester, Pennsylvania
This was the first time I had tried YourMechanic. What a great idea this service is - I hate dropping my car off and making all of the arrangements back and forth to get service. After reading several reviews, I decided to try the service myself. This review is from a real customer, and this is my real experience. First off, it is pretty cool that you can read feedback on the mechanic you are choosing before the appointment so you know who is showing up at your location. Shawn arrived with a YourMechanic identified on the side of his car, and was wearing a shirt branded with YourMechanic. Even though the appointment was scheduled at 8:00 am on a Friday morning, he was exactly on time. He laid out a tarp under the engine on the driveway as to protect any fluid leaks from staining my driveway and had whatever catch pan he needed as well. Shawn was personable, knowledgeable, and patient about any questions I had, whether regarding the schedule service for the thermostat change or questions about my engine in general. The work I requested was performed timely, skillfully , and thoroughly. Not once did I feel like my service was rushed. As he was topping off the anti-freeze and running the engine, he inspected other issues and noted some things that he pointed out to me that may or may not need future attention. It was a great experience. Shawn did a great job and I was completely satisfied. YourMechanic would be smart to try and retain this mechanic as he is an asset to the reputation of this company. Depending on the type of service I may need, I would definitely use this service again, and would not hesitate to request Shawn again.

Trevor in Oceanside, CA is excellent. Correctly diagnosed my car’s problems, provided me with a fair quote for only what was needed (no scamming/upselling/etc), then came back a couple days later for a follow up to complete the repairs. Arrived on time, quickly fixed what was wrong, and my car is running perfectly after paying for repairs that cost only a fraction of what I was expecting. Would definitely recommend.
