2012 Chevrolet Express 3500 OEM Parts and Accessories

Getting parts right on a full-size van starts with knowing which generation you are working on. One-ton full-size van available as a passenger van, cargo van and cutaway.

The 2012 model year falls inside an established production run. Most part numbers had settled by then, but drivetrain and package choices still divide the catalog. Wheelbase, roof height, and passenger versus cargo configuration all change part numbers on full-size vans.

The parts we ship most for the 2012 Chevrolet Express 3500 are water pumps, ignition coils, steering linkage, mirror assemblies and headlamp assemblies. These are genuine GM parts, engineered by the team that built the vehicle and held to the tolerances the original calibration assumed. On a full-size van these are the components that carry load and heat, and they are where an aftermarket substitute costs you the job twice.

One thing worth knowing about buying OEM: the part number ties back to GM's own engineering records, so when a component is revised the supersession is documented rather than guessed at. Aftermarket catalogs have no equivalent, which is why a listing that says it fits a range of years is often wrong at the edges.

Run your VIN before ordering. It takes a few seconds and it is the difference between installing the part and shipping it back. We ship from Dallas, and in stock orders placed by 3pm Central usually go out the same business day. If you are servicing more than one vehicle from that year, our 2012 Chevrolet catalog covers the rest of the lineup.
