Smelling coolant randomly and saw this. Coolant on top of the front diff. Can’t see where its coming from though.

I can’t tell…. There’s crusty coolant all over, from the top of the oil cooler down.

I have a 2.0L so not much help on location, but find out where your water pump is and check the bolts. I know on at least the 2.0L it is a known issue. We got back from a wheeling trip in South Dakota and inspecting my undercarriage for damage, I smelled coolant and found some on the top of the front diff as well. Luckily a buddy had the same issue and had told me about the bolts coming loose. I located mine and snugged them up and it stopped. Dealerships know it's an issue and typically remove them and use blue loc-tite from what I hear.

Thank you for your response! I have an appointment to drop it off tomorrow.

under warranty?
Yes. Still under the 3/36k thankfully. The tech working on my jeep is a jeep guy. Has a 23 JLUR that hes dumped about 25k into. I feel good about it… said they were a week behind but he’d get it on the rack for tomorrow morning anyway…. Nice

Water pumps are no big deal on these, it will be quick.

Water pump done and they also changed the timing chain cover. 5 days wasn't a bad turn around.

I went through 3 water pumps on my 3.6 in my WK2 within 48k miles. Water pumps are all too common on the pentastar.

What the hell? That doesn't make any sense at all.
I'm not sure why the Timing chain cover was changed. I cant get a straight answer.

Seems to be one of the weakest links. I've done a lot of reading on the water pump issues over the last few days.

Are you sure it wasn’t the water crossover pipe on the timing cover? There’s no reason to R&R timing cover based on the symptoms unless they blew the threads out of the timing cover with an impact when installing the water pump.
