Driving to work & serpentine belt broke. My husband thinks the water pump may not be working. Is there anything else that may have caused a fairly new belt to break?
what causes the serpentine belt to break if not old?
on 1997 Jeep Grand Cherokee
Suspect either your idler pulley or belt tensioner pulley. Take belt off and spin pulleys- maybe bearings on either binding up and throwing belt off track and shredding.
Several things can cause a belt that is not old to fail. If any components like power steering pump, A/Compressor, alternator, harmonic balancer (not just idler or tensioner) has a pulley that has a loose bearing or bent will cause wobble, has a bearing or internals seizing, has damage to a pulley that is damaging a belt, has a pulley misaligned or a defective belt. If you need your vehicle checked out and repaired please call Andrew of Kris 456-0722 at CarMasters, thanks, Jim
