Wondering if anyone else experienced this especially now that it’s getting much colder out and temperatures reaching below freezing. After driving on a 2 hour trip recently a loud squealing noise was coming from the passenger side of the engine when parked and idling, obviously some sort of belt or tensioner I assume. What’s odd is it only appears after long periods of driving. At start up after sitting it sounds perfectly normal no squeal. It’s the 3.2 v6 also.

Hey @connord ,
In order to do any of these, you need to pull the lower radiator and heater return hoses so best thing to do is replace:
1. The Serpentine Belt,
2. Tensioner and
3. Idler wheels (there are two, one smooth and one grooved) at all the same time.
None of these parts are expensive, can all be purchased on RockAuto and are straight-forward to change. Remove front passenger wheel and liner and you can get a pretty much everything. Since you have a 2015, you're probably at the mileage for them to be changed anyway.

For the V6, these are the exact parts needed from Rock Auto.

As @Flybynightcru mentioned, the toughest part is that you need to take the two return hoses off. Have a bucket ready to catch the coolant that will drain out. if you've never drained and flushed your cooling system, this is an excellent time to think about it. Note, I never can re-use these new style clamps so you need to get replacement worm-gear or constant tension types.

The smooth idler was only available as Mopar, no aftermarket available. If there was an aftermarket option I would have gone for it. That Mopar idler if I recall was more expensive than the other idler, tensioner and belt combined
