Question about 2005 Chrysler PT Cruiser
After driving a couple of miles the temp gage goes up to red, dings 6-10 times, then gage goes back to normal. Engine is not getting hot, everything is working OK. Had a new thermostate installed but the temp gage still does this about once a day when I'm driving. Mechanics I have taken the car to can not find anything wrong with it. Could there be a sensor or electrical problem?

SOURCE: temp gauge off charts
Are you mistaking the engine temp sensor for the engine temp sending unit? The temp sensor is for the fuel injection system and the temp sending unit is for the gauge. If you asked for a sensor thats what they sold you. You need to ask for a sending unit.

Hi there iask,
I could call myself ianswer. My name is Mike. I've got a 91 wrangler that used to do the same thing.
With me it was an air pocket. The temp sensor responds to a heavy medium like water, not air. As an air pocket circulates and comes into contact with the sensor, your gauge will fluctuate.
I'm sure you checked the coolant levels already, but hear me out. What I'm suggesting is like chicken soup, it can't hurt, it can only help.
Just because a radiator looks full, doesn't mean it is. Air pockets can exist in the engine and heater core. We're going to get rid of any.
Checking the coolant level.
Remember: Good things come to those who Rate.

air sometimes gets trapped in the heater hoses or heatercore itself pull the upper heater hose off the block,hold it in the air and try to fill it,that should push the air out of the line

there is one fuse for all the dash gauges, so chances are you have a wiring problem to the gauge sender on the engine or the gauge is defective, which is rare.
