Knowing the number for an automobile component can be an immense help when you're trying to buy a replacement part. Having the specific number will simplify your search for a new part because you won't have to search all makes, models and years. This comes in especially handy if you are trying to find a somewhat uncommon part. Part numbers can be found by calling a dealership or on the Internet.
Call the local dealership for your make of car and request the service department. Many dealers also have a separate parts department.
Give the department the basic information about your car. This means the year, make, model and trim level. All of this information can be found on the cover of your owner's manual, though trim level may be displayed on the rear end of your car.
Request the number for the specific part you are looking for. Write down the number and save it for your parts search.
Go to an auto parts supply website such as www.parts.com or www.partstrain.com.
Enter the basic information for your car using the drop down menus on the homepages of these sites. This information is the year, make, model, and trim level.
Enter this information into the site's search engine by clicking on "Submit" or "Find Parts."
Find the part you want from the list provided and write down the number that is displayed under the "Part Number" column on the website. This is the part number.
Some larger auto parts supply stores have internal databases of parts numbers. Part numbers can be acquired from these stores in the same way as from dealerships.
