Genuine GM Parts for the Cadillac DeVille

Select The Year Of Your Vehicle Below

Limited availability on pre-2010 parts. Factory parts for vehicles older than 2010 are getting harder to source every year. We can still get many of them through GM remaining stock and vintage parts channels, but supply is limited and availability changes without notice. If your part shows in the catalog, order it and we will confirm availability right away, or contact us first and we will check before you buy.

The Cadillac DeVille ran from 1959 through 2005. Full-size front-drive sedan for the later generations, with the Northstar V8. Because that run covers more than one engineering generation in most cases, the single most important thing you can do before ordering is confirm which year you are working on. Parts that look interchangeable across a nameplate very often are not.

Livery and fleet versions of these sedans often carry different suspension and cooling parts from retail cars. Everything on this page is a factory GM part, built to the original specification and carrying the original part number.

The parts we move most on the Cadillac DeVille are water pumps, ignition coils, intake manifold gaskets, window regulators and headlamp assemblies. On a full-size car these are the components where the difference between a factory part and a discount replacement shows up fastest, because they carry load, heat or both. If you are not certain which version you have, give us the VIN and we will confirm fitment before you check out.

In stock orders placed by 3pm Central typically leave our Dallas warehouse the same day, so most of the country sees short transit times. If you are working on something else in the lineup, our full Cadillac catalog covers the full catalog.
