Problems with serpentine belts Longmont, CO drivers notice, usually start small. A short squeal on a cold morning, steering that feels heavier than usual, or a battery light that will not stay off. Josh's Mobile Mechanic Service comes out before those signs turn into a breakdown. We inspect the belt, tensioner, and pulleys where the vehicle is parked and show you exactly what is worn or out of line. If a new belt is needed, it is fitted on-site with parts matched to your car or truck, and we confirm proper routing and tension before leaving. No towing across town, no waiting room delays; just direct, mobile service that keeps your vehicle ready for daily Longmont driving. Contact us!
