Ever had that nagging worry about your Jeep's serpentine belt slipping at the worst possible moment? Like when you're deep in the trails or just merging onto the highway?
Over time, the belt tensioner in your Jeep Wrangler V6 3.8L can wear out, leading to loose belts that squeal, slip, or even snap. This isn't just annoying—it's a safety risk that can disable accessories like your power steering, alternator, or AC.
