2025 GMC Sierra 2500 HD Maintenance Schedule
    7,500 Miles
    During your initial scheduled maintenance visit, your vehicle will undergo an oil change, and the oil filter will be replaced. Though modern engine oil is durable, it degrades over time and gathers impurities. Fresh oil ensures smooth engine function and longevity. This appointment will also include a comprehensive check of your truck’s systems. These essential tasks will be performed at each service visit.

    15,000 Miles
    At 15,000 miles, along with the routine oil change and inspection, the engine air filter and cabin air filter might be replaced. The cabin air filter helps keep dust, pollen, and other airborne particles from entering the vehicle. A clogged filter can affect the air quality and the ventilation system’s performance, so it’s important to replace it when necessary.

    30,000 Miles
    Once your truck hits the 30,000-mile mark, additional fluid levels, such as coolant, brake, and transmission fluids, will be checked and topped off or replaced if necessary. Our service team will also inspect components like the spark plugs, air filter, and fuel filter to ensure everything functions properly.

    60,000 Miles
    At 60,000 miles, more comprehensive maintenance is required, including changing the engine coolant, differential fluid, and transmission fluid and filter. Depending on their condition, the timing belt might need to be replaced, and the spark plugs may need changing. Our certified service technicians will also inspect vital components like the brake pads, shocks and struts, and tires.

    90,000 Miles
    At 90,000 miles, another thorough inspection and servicing is due, including the engine coolant, automatic transmission fluid, and differential fluid, if needed. The service team may also replace the timing belt and the spark plugs and adjust the valves.

    If your truck is due for service, you can rely on the experts at the Jim Cook Chevrolet Service Center to handle it. Book your appointment online or give us a call. We’re here to make maintaining your 2025 GMC Sierra 2500 HD as convenient as possible.
