How do you find the serial numbers on auto parts?

To find the serial number of a car part, sometimes you can open the hood and look at the parts, but often you need to seek out the help of an auto dealer. You need the vehicle make, model, year of manufacture and the VIN.

By entering these four pieces of information into an auto dealer's database, he can find the part numbers. The VIN, or Vehicle Identification Number, is a unique 17-digit number. To find it, look in one of several places, such as the corner of the windshield or the inside of the door. You can also consult your registration.
