      The Thermostat could possibly be the problem. However, without the presence of your vehicle we would not be able to properly diagnose it nor provide you with a 100% answer. We would suggest that you take your vehicle to a certified mechanic for further diagnosis.

      Yes. Also could be the cooling fan or the water pump. And the sensors don't work right if you leave air in the lines after overheating.

  • Q:

    does this have a fail safe design so that it locks open in an overheating situation to allow coolant to continue to flow?

      Unfortunately, the thermostat does not have a fail safe to lock it open. The thermostat getting stuck close is a common automotive problem for overheating. When you have an overheating problem that is one of the first things a mechanic checks. For more information you can contact us at 1-877-ADVANCE or visit
