How to Locate GM Part Numbers

If you choose to perform repair work on a GM vehicle, make sure you know how to find the right parts. Although many parts have a case number printed on them, this is not the same as the part number.

Instructions

1

Obtain the vehicle identification number, or the VIN, on your GM vehicle. It is typically located under the windshield on the drivers side dashboard.

2

Contact your local GM dealership with the VIN number. The VIN number indicates the year, make, and model of your GM vehicle, as well as where it was made. It can also tell you the transmission type and the engine code. Using the VIN number, the dealer will be able to help you find the right part numbers for your particular vehicle.

3

Type your VIN into an online decoding service. If your local dealership is unable to help, online decoders can be used to break apart your VIN number and find the corresponding parts number. Double check when entering the VIN -- including every number in is important.
