Question about 1996 Jeep Grand Cherokee
The tempeture gage fluctuates for no apparent reason. Its not the thermostate and it has a new radiator with new hoses.
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.
