Alpine GMC – Recommended service and maintenance schedule for GMC Sierra 1500

Keeping your GMC Sierra 1500 on schedule protects performance, safety, and resale value. At Alpine Buick GMC in Littleton, CO, we make maintenance straightforward with Certified Service technicians, GM Genuine Parts, and ACDelco components, and convenient online scheduling. Whether you tow, commute, or conquer winter roads, a proactive plan prevents small issues from becoming major repairs. The outline below reflects common intervals for many Sierra 1500 model years and engines, including 2.7L Turbo, 5.3L V8, 6.2L V8, and 3.0L Duramax Turbo-Diesel. Because usage, climate, and equipment vary, always follow your Owner’s Manual and the in-vehicle Oil Life Monitoring System, and contact GMC or our team for recommendations tailored to your truck.

Monthly/Before trips: Check tire pressure with TPMS, engine oil level, coolant, washer fluid, exterior lights, and wiper condition; top off as needed.
