Installation Notes and Tips

Before installation, verify engine code, timing cover configuration, and application notes against the vehicle. This kit is intended for timing system service on the listed Buick, Chevrolet, Oldsmobile, and Pontiac models, including long-tail applications such as a timing chain kit for 1995-1999 Chevrolet Lumina or an engine timing set for 1994-1999 Pontiac Grand Am. Follow factory timing marks and service procedures carefully during assembly.

Because the kit does not list a tensioner, gaskets, or drive sprocket as included, confirm whether those parts need to be sourced separately for the repair. The part number ZC-9-0385S should be matched to the exact engine application before installation.

Quality Assurance

INA timing chain kits are built to cover the essential timing components needed for a complete repair. Schaeffler also specifies a high-performance chain additive from Liqui Moly for certain applications to reduce friction during break-in and lower run-in wear.
