GM Service Manual Online
For 1990-2009 cars only

Caution: You can be injured and the vehicle could be damaged if you try to do service work on a vehicle without knowing enough about it.

   • Be sure you have sufficient knowledge, experience, the proper replacement parts, and tools before attempting any vehicle maintenance task.
   • Be sure to wait until the engine and any attaching parts have sufficiently cooled before tilting the cab to service the vehicle.
   • Be sure to use the proper nuts, bolts, and other fasteners. English and metric fasteners can be easily confused. If the wrong fasteners are used, parts can later break or fall off. You could be hurt.

If doing some of your own service work, use the proper service manual. It tells you much more about how to service the vehicle than this manual can. To order the proper service manual, see Service Publications Ordering Information .

Keep a record with all parts receipts and list the mileage and the date of any service work performed. See Part D: Maintenance Record .
