How can you find a GM part number?


Quick Answer

While General Motors part numbers are not generally stamped on each part, a number of online and retail resources are able to locate the part number given the vehicle’s year, make and model, or the vehicle identification number.

To find the VIN of a GM vehicle, look at the vehicle’s registration, title or insurance documents. If no documentation is available, look for the VIN on the front of the engine block, where the driver’s side dashboard meets the window or on the driver-side doorpost. All types of GM parts have assigned part numbers, including belts and hoses, alternators and starters, filters, water pumps, and window regulators.

Online retailer GM Parts Department also offers an online catalog of original equipment manufacturer parts that is searchable using the online catalog. Select the vehicle year, make and model, or search for a part by part number. This online retailer also offers a multi-part number search.

The number printed on most GM parts is a casting number and not a part number. It is very difficult to decipher a part number using only a casting number.
