The Hydraulic Alternator Belt Tensioner is exposed to a lot of dirt, salt, and other debris due to its front lower location. This can cause the tensioner to seize and not allow the belt tensioner to adjust. Replace your belt tensioner with this OEM high quality hydraulic tensioner for many years of reliable operation to come.

This is an OEM Febi Upper Idler Pulley, also known as the roller pulley or deflection pulley. The upper and lower idler pulleys are known to be the primary sources for 'belt squealing'. The pulley is also encased in rubber which will crack over time. If left without service the rubber could fail completely, chucking the belt and leaving you stranded. Replacement is a very simple procedure and can be done anytime the fan is off the engine (belt replacement, water pump service, alternator replacement, etc).
