• Timing system maintenance on Pontiac LeMans models with interference engine applications
• Replacement on 1990 Pontiac LeMans with tensioner pulley-equipped timing service

Installation Notes and Tips

Before installation, confirm the engine code, pulley condition, and timing marks on the engine components. Because this belt has no timing marks, use the factory service procedure and proper timing tools to set alignment accurately. Replace worn tensioners, idlers, and seals as needed during timing service, and inspect the belt path for contamination or damage before starting the engine.
