How to Find a General Motors Part Number

If you plan on replacing parts to your automobile, you will need to know exactly which part is required. General Motors has replacement parts available if you take your car into the dealership, and they will know what type is needed. If you plan on doing the repair yourself and want to know what to order, you will need to know the part number. A wrong guess can cost you money and waste repair time, so be sure of what part you need before attempting any repairs.

Skill level:
Moderately Easy


  1. 1

    Go to the GM Parts Direct website ( There are a number of websites online that sell parts, but most either will not list the parts number or only have a limited selection. GM Parts Direct allows you to search by car model and year.

  2. 2

    Click the "Catalog" tab on the webpage menu.

  3. 3

    Click on the following text at the bottom of the screen: "I have read the above and agree with catalogue policy and wish to start catalogue NOW!"

  4. 4

    Select the year, make and model of the vehicle you are trying to find parts for, and then click "Search." If your vehicle is older than 1990, you will need to scroll down to the bottom of the "year" category and select "Classic Vehicles." From the new screen, you can select the year and make of the pre-1990 vehicle (you can select between a body parts catalogue and mechanical parts catalogue).

  5. 5

    Select the part you need from the left hand list. For instance, if you are looking for a parking brake control, you would select "Brakes," then "Parking Brakes" and finally "Parking Brake Control."

  6. 6

    Find the part you need and then select "Add to Cart."

  7. 7

    Click "Submit Cart." You will not actually purchase the part, and you do not need to enter any personal information. The cart screen will list the part number under "GM Part #."
