2007-14 Chevrolet/GMC Full Sized Truck Routine Maintenance Reference Guide

(Covering Chevy Silverado, Avalanche, Tahoe, and Suburban, and GMC Sierra, and Yukon, two- and four-wheel drive, with gasoline engines.)


Modern cars and trucks do not need as much maintenance as the vehicles of 25 years ago, but they still need periodic checks and inspections. You no longer have to tune and adjust the engine every six months or change the oil every three months/3,000 miles, but to protect your investment and ensure years of service, regular fluid changes and tire rotations are essential. Catching a problem before it happens, through regular inspections, will save you hundreds of dollars and countless time.

This quick reference guide answers many questions that occur during routine maintenance tasks. With this chart and a set of common tools, you can perform the majority of regular service yourself at home. For more information and step by step instruction, refer to the relevant section of Chilton manual 28626.

Maintenance Schedule

2006 Chevy SilveradoWhat follows is our recommended minimum maintenance intervals for daily driven vehicles, based on our years of experience and the factory schedule. We encourage you to use our schedule and perform the maintenance yourself, to save money and needless trips to the dealer. In many cases, our intervals are shorter than the factory’s recommendations, but frequent maintenance will improve the service life of your vehicle, as well as enhance the efficiency, and improve the resale value. If your vehicle is frequently driven in dusty areas, driven at low speeds for extended periods, allowed to idle at length, used to tow a trailer, or used often for short trips (less than four miles at a time) in below freezing temperatures, even smaller intervals are recommended.

When you purchase the vehicle, follow this maintenance schedule and keep a written record and receipts to protect the warranty and resale value. If you buy the vehicle new, an initial maintenance check is often included at no cost (check with the service department for more information).
