Recently my temperature gauge on my car started to fluctuate. It would rise, so I would pull over and shut off my car for a min. or two and the guage would return to normal. There tends to be no other signs that my engine is overheating. It tends to rise when I am driving at a slow rate of speed (usually 35 & below). I brought it to the mechanic & they changed my thermostat which helped for a few weeks. Then it started doing it again. The mechanic isn't sure what it is, because he said the guage doesn't change for him. It doesn't always rise when I am driving slow, but I did notice that if I have my heat on, when my guage starts to rise, it starts to blow out cold air, instead of hot. This makes me think it is more than just a bad sensor issue. Any help/suggestions I can get is greatly appreciated!!!!!!!

Blowing cold air when the gauge is reading high means you have a low coolant level, check it and add if you have too. One other thing to cause a high temp reading is your cooling fan isnt kicking on at the right tempature, this is controlled by a sensor.... of course....so you might need to get a new sensor. I would check your coolant level first. Also fill your overflow tank to the right level as well.

It could be an intermittent clog in the system but I doubt it. It's a good idea to change the hot temp sensor antway because it's cheap and easy. Other things to consider are; Is the thermostat bad or in backwards? Sometimes they are bad right out of the box and installing it backwards is an easy mistake to make. Next, is the cooant level up to where it's supposed to be? There are two levels to fill to one is for hot and one is for cold. Next, is the pump bad? The pump does not have to leak to be worn out. Many are made with teflon impellers instead of steel ones these days. Last and worst case is that you have a bad head gasket and the water isn't circulating as it should.

Sounds like you have some air in the system. I had an '87 Accord that did this after I changed the antifreeze. Some vehicles have a valve to burp the air out of the cooling system. If you can't locate that, just make sure the radiator is completely full. My bet is the sensor is fine.

did u have the mechanic check ur radiator- either u are out of coolant or u have a leak in the radiator.
usually heating up of the engine is connected with the radiator.
goodluck with that.
