Default Temp gauge on dash is spiking red

My temp gauge in my gauge cluster will gradually go all the way to the red and then come back down to the neutral position. The car doesn't seem to be over heating but I wanted to know if it was an electrical problem anyone has heard of.

It does it at least once every time I drive.

why do you think it isn't overheating? I'd trust the temp gauge more than a feeling. If the spike is instant, it probably electrical. if the spike is consistent with driving conditions, it is most likely actually overheating. (generally you don't get any symptoms of overheating until your head gasket lets go or your radiator blows an endcap, it will drive as good if not better than normal.)

It drives normal. The gauge will slowly go up to the red and then slowly come back down to average like a minute later.

My first thought would be thermostat, as already mentioned by GreenMarineSVX.

Have you changed the coolant lately? Could be an air pocket.

Nope I have not in a while. I will try that first before I start shelling out too much money. Thanks

Err, yeah, that doesn't mean much. As someone mentioned, you would probably never be able to tell that your car was overheating if it weren't for the temp gauge, until your HG or something worse broke.

I'd get it looked at ASAP. It could be something as simple and cheap as a thermostat, but continuously overheating your engine, especially to the red, is putting your car at risk for other major & expensive issues. Blown head gaskets, warped or cracked heads, cracked block, etc etc.

If you have a laser pointer IR thermometer, perhaps you could use it on parts of the cooling system/engine, when the gauge reads in the red.
