This OE style replacement idler pulley assembly is specifically designed to provide tension on the water pump to crankshaft pulley belt on special Hi-performance and fuel injection equipped Corvettes. It's important to note that this assembly was not used on air conditioning or power steering equipped Corvettes.
This assembly comes with a zinc plated 3-3/4" O.D. pulley that provides superior durability and performance. Please note that over-tightening the belt can cause premature failure of the idler pulley bearing, which would void the warranty. Exercise caution when providing belt tension to ensure longevity and reliability.
