Overheating issue?

Just got my 2013 wk2 and it consistently has the coolant temp reading between 245 and 250 Fahrenheit ... Normal?

Re: Overheating issue?

Now it's not shifting properly wth.... I'm in like 3rd gear and put my foot down and it won't shift instead just hangs at 4000 rpm for like 3 full seconds..

Is it Eco mode or something else

Re: Overheating issue?

While GC engines run a little on the hot side those are higher coolant temps than most people post out here.

Your two problems are most likely interrelated.

It's not Eco mode doing that. And now with your trans acting up you need to get it into your dealer and have it checked ASAP before it starts going into limp mode.

Not normal. 190-205 is about the normal range of coolant temps.

Re: Overheating issue?

It was a faulty thermostat.. And I was reading that the delay of the shifts was directly caused by the temps thanks mdbones

That makes sense. Holding shifts turns the water pump faster. With a functional tstat it would help to alleviate an overheat condition.

Jeep Grand Cherokee Transmission Shifting Problem

Yep, that makes sense. It's good that it was a relatively simple problem.

Re: Overheating issue?

Just for the curious, on a 95+ Florida day after about an hour at 70 with the AC on my coolant reads 203-204, oil 185, trans 167. Same towing a 3500 lb trailer: 203-204, 192, 180. '12 3.6.

Have always wondered a bit why the oil and trans are so low.
