| ACDelco Engine Components offer installer-friendly product categories -- such as intake manifolds, intake manifold gaskets, engine oil cooler lines, tensioners, balancers and pulleys, etc. -- for most GM cars, light-duty trucks and SUVs on the road today. All are OE validated by GM Engineering to assure proper form, fit and function. This is important on these high-labor-hour heavy repairs. The part designs are enhanced to incorporate OE updates, upgrades and Technical Service Bulletins (TSBs). Only ACDelco can offer complete late-model coverage.
Service Tip: Clean and sufficient oil is the key to getting maximum life from your timing system. Premature component or complete system failure can often be traced to oiling issues. Always use manufacturer-recommended oil and follow manufacturer-recommended service intervals.
 Benefits of Purchasing a Complete Kit Purchasing individual components may be less expensive up-front, but a complete Timing Chain & Component Kit provides added benefits:
| ✓ | Improve Engine Performance: A new chain may not mesh with worn sprockets, and worn tensioners / guides won't apply enough tension, ultimately resulting in poor engine performance. Replacing all timing components together will make the whole system run more efficiently. |
| ✓ | Save Time & Money: The cost of the kit is often less than buying all of the components individually, and replacing all of the components at the same time means you only have to do the job (or pay for labor) once.
