Overhearting
I have a bone stock engine in my 99 Cherokee. I dozed off in the parking lot the other day waiting on the wife. When She came out the car was running pretty dang hot. I figured I get some air moving so I started down the road and in about a minute the temp came down but not a little at a time.....all at once. It drop to normal in about 2 seconds. Sticky thermostat? Any other thoughts? Mark

If the coolant temperature creeps up ONLY at idle but stays normal when you're moving down the highway, the #1 suspect is a bad "fan clutch". Often overlooked, inexpensive and easy to install.

Fan clutch seems OK. Not locked up, and has a little drag when cold. Found it unusual that the temp dropped in a couple seconds when it finally went down.

But always review all cooling system components when symptomatic.
