Jim Cook GMC – Recommended service and maintenance schedule for GMC Sierra 1500
Your GMC Sierra 1500 is built to haul, tow, and tour, and the best way to protect that capability is a simple, repeatable maintenance plan. At Jim Cook Chevrolet GMC in Marion, NC, our Certified Service experts combine factory training, GM Genuine Parts and ACDelco components, and a thorough Multi-Point Vehicle Inspection to keep your truck feeling tight, quiet, and confident. Whether you drive mostly highway miles or spend weekends on gravel and job sites, we tailor recommendations to your truck’s engine, 2WD or 4WD configuration, and usage. We also sync service timing with the Oil Life Monitoring System, so oil and filter changes happen when your driving actually demands them. Every visit includes a tire rotation paired with a tread and alignment check, brake measurements, fluid tests, and a battery health report, so small issues never have the chance to become big repairs. Our team documents findings, explains priorities clearly, and schedules follow ups around your calendar. From air and cabin filter replacements to transfer case and differential services, we help you stay ahead of wear while preserving warranty coverage and long term value. We also offer easy online scheduling and service reminders aligned to your mileage, so you never miss an interval.
- Every 7,500 miles or 1 year: Engine oil and filter; rotate tires; inspect brakes, battery, lights, wipers; top off fluids.
- Every 15,000 miles: Replace engine air filter as needed; inspect cabin air filter; check belts and hoses; torque suspension fasteners.
- Every 30,000 miles: Test brake fluid and replace as needed; service transfer case fluid on 4WD; inspect transmission fluid condition.
- Every 60,000 miles: Replace transmission fluid and filter if equipped or under severe service; inspect or replace coolant as specified.
- Every 100,000 miles: Replace spark plugs on most engines; exchange coolant; service front and rear differentials; inspect water pump and belt.
- Before heavy towing or off road: Verify tire pressures including spare; check alignment, trailer wiring, and brake pad thickness.
Intervals can vary by model year, engine, and driving conditions, so always consult your Owner’s Manual and contact the manufacturer or our advisors for details specific to your VIN. If you tow frequently, idle often, drive short trips, or travel dusty roads, follow severe service guidance, which typically shortens fluid and filter intervals. Keep an eye on your Oil Life Monitoring System, tire pressures, and any Driver Information Center alerts. Tools like OnStar® Vehicle Diagnostics can help you monitor key systems between visits. After windshield or collision repairs, certain Advanced Driver Assistance Systems such as Automatic Emergency Braking may require calibration for proper performance. We can also review alignment after curb impacts, check trailer wiring and brake controller operation, and document everything for service history value. The easiest way to stay on track is simple—book your next visit before you leave, stick to consistent tire rotations, and address small noises, leaks, or warning messages promptly.
