My jeep has been overheating recently, but as soon as I turn on the heat, the temp drops to normal or right above normal in a matter of 3-5 seconds. When this first happened to me, I thought it might have been my water pump getting ready to go out. But now a couple of weeks have gone by and I keep turning on the heater when it overheats and it drops the temp to normal. Do I have a bad thermostat, or any idea as to what it may be?

Is the cooling fan working before you turn on the heat? Youy can test the thermostat in a pot of boiling water to see if it's opening and closing properly. I've had this overheating problem when I was in need of a good flush! Just a couple thoughts!

Haven't thought about the cooling fan. I might need to flush the system any way, it's been about a year or so since I've done that.
