Belt Tensioner Replacement - Houston's Premier Auto Repair Facility

Belt tension is the key to proper functioning of the accessory belt drive system. Worn belt tensioners loses damping ability creating excess play. Common failures linked to tensioners include belt slipping, misalignment, failure of the tension damper, insufficient belt-pulley contact and the obvious weak tensioner. 

Today's modern vehicles require the belt tensioners to be replaced at the same time as the belts, and for the technician to physically inspect all additional relevant pulleys of the system while the belt is off. 

The video below is produced by one of the leading belt, tensioner, cooling system products supplier in the industry which clearly explains the potential problems which could arise from the accessory system.
