Squealing Noise from Engine Bay on 2020 Durango GT - Serpentine Belt?

Vehicle: 2020 Dodge Durango GT

I've got a 2020 Dodge Durango GT with about 45,000 miles on it. Lately, I've noticed a distinct squealing sound coming from under the hood, especially when I first start it up in the morning or when it's damp outside. It usually goes away after a few minutes of driving.

I suspect it might be the serpentine belt. Is this a common issue for this model year? What's involved in checking it, and is it a DIY job for someone with moderate mechanical skills?

A squealing noise from the engine bay, especially on startup or in damp conditions, is a classic symptom of a worn or loose serpentine belt. Here's how to approach it for your 2020 Dodge Durango GT:

  1. Inspection:
    • Visually inspect the serpentine belt for cracks, fraying, glazing (a shiny, smooth appearance), or missing ribs. A flashlight can help. Any of these signs indicate it's time for replacement.
    • Check the tensioner pulley. With the engine off, apply pressure to the belt; there should be some tension, but not excessive. The tensioner itself can also fail, leading to improper belt tension.
    • Listen closely to the idler pulleys and other accessory pulleys (alternator, power steering pump, AC compressor) with the engine running (safely!) to pinpoint if the noise is coming from a failing pulley bearing rather than just the belt.
  2. Commonality: While not a widespread 'issue' per se, serpentine belts are wear items. At 45,000 miles, depending on driving conditions, it's certainly within the realm of possibility for it to start showing wear.
  3. DIY Potential: Replacing a serpentine belt on a Durango with moderate mechanical skills is generally doable. You'll need:
    • A new serpentine belt (ensure it's the correct length and width for your specific engine).
    • A serpentine belt tool or a long breaker bar/ratchet with the correct size socket for the tensioner pulley bolt.
    • A diagram of the belt routing (usually found under the hood or in your owner's manual).
  4. When to See a Shop: If you're uncomfortable working around engine components, can't locate the tensioner, or suspect a failing pulley bearing (which might require specialized tools or more complex removal), it's best to take your Durango to a professional mechanic. Ignoring a failing belt can lead to loss of power steering, alternator charging, or AC, potentially stranding you.
