Another possible cause is your coolant sensor. if the sensor goes bad, it will drip coolant but won't notice it because it just seeps down the engine components. Most people don't even realize that there is such a sensor. it will send a faulty reading that its overheating when the coolant level is fine and when enough coolant does seep out it will still say its overheating because it is at that point. I would definitely look into checking your coolant sensor as the cause since it's so hard to even see that it is leaking and its super easy to take out and replace. hope that helps if you're still having problems

Are you putting the thermostat in correctly? It it will not work backwards.

And to confirm that there isn't a different problem, take the thermostat out all together and see if it overheats.

Engine not fully warming up is not usually caused by the thermostat. Stats usually fail closed, not open.

You will want to check the water temperature sending unit or gauge after verify the water temperature with an external calibrated thermometer. You can attach and insulate the external thermometer to the housing where thermostat is located.


Reply back what you figure out. I will be happy to help you further.

it could be the radiator isn't working properly, I had that problem with my Dodge truck and even though my radiator had been replaced two years earlier when I took it to a radiator shop I discovered it was bad and that was the problem the whole time.

If the top hose is hot and the bottom is cold, your definitely not getting circulation. You,ve already done alot of work to this vehicle so you have pretty much answered your own question. About the only thing left is the heater core. Of course, I dont want to be the one to tell you it is definitely the heater core because obviously I am not looking at the vehicle. But If i was a betting man, thats where my money would be.

Are you losing coolant. If you are I would check your heater core which is located under the glove compartment.
