Wj Jeep got hot driving on mildly hilly highway

Part way into my drive back from the beach I notice my jeep is running a little warmer than usual. The temp kept increasing until it got a hair over 210 and I stopped and let it cool down.

When that was happening the blower motor was running, but I didn't have the AC on.

I let it cool for about 45 minutes and then continued on my way home with the AC and blower motor completely off. It ran what seemed slightly warmer than usual, but never touched 210.

When I got back in town I tried the AC again and the temp immediately went up to 210, so I turned it off to prevent it getting any hotter, with it off the temp went back down to a few hairs under 210 where it was running on my drive home.

I'm just happy I made it back without it overheating.

When cold, the coolant level is at the add mark.

This morning I idled it in my driveway for a good 30 minutes with the AC on. The temp never hit 210.

My electric fan seems to be working fine, as it was spinning while I had it idling this morning.

One other thing to note is that my girlfriend hit the top of her foot on this under the dash on the passenger side and said it was really hot.



Could that have anything do with the overheating? And what exactly is it?

Thanks guys!

New radiator. The hot area is taking up the job until you replace the radiator. Not difficult but possibly needed. Plenty of support for the issue you are facing.

In reality though, going to 210 is actually normal op temp. Even a little more is OK. Continuing to climb is the issue. No burning platform yet but plan for the fix soon as you can.

Good to know. When it when over 210 it went over just a bit. It was basically the inverse of where my Jeep has normally ran (if that makes any sense).

Also, what exactly is that I have circled. I'm assuming it has to do with the heater.

The circled spot is where the heater core is at in the HVAC box. I'm assuming your engine got too hot and it made that hot as a result. I'd try pressure testing the radiator to check for leaks, and if you're leaning coolant its probably the radiator. Those Chrysler radiators don't last.

Jer brings up a great point.... if the Heater Core is actually leaking, that plastic area would possibly contain coolant in it (also get very hot) and you may also find coolant under the carpet on the pasenger side footwell.

Pull back the carpet & report back on what you find.
