Description

The GM Drive Belt Idler Pulley (10055890) is a genuine OEM replacement part designed to address noisy idler pulley bearings in specific GM vehicles. This pulley is constructed from aluminum and nylon and features 6 grooves with an outside diameter of 5-3/16 inches. This idler pulley is intended for 1991-1993 8-cylinder engines and is designed for applications without air conditioning. It is a direct replacement for the original component, ensuring proper tension and alignment of the drive belt system. Fitment is specific to a range of GM vehicles from 1988-1993, including Chevrolet Camaro, Chevrolet Caprice, and Pontiac Firebird models equipped with 5.0L V8 or 5.7L V8 engines.
