The 2005 Cadillac Deville was the last year in the eighth generation for this popular vehicle that started in the 1950s. This year may have been the last production year, but GM didn't skimp on luxury amenities. Replaced by the DTS, the DeVille retired. If your DeVille still does a lot work for you, treat it well. Buy only genuine OEM GM parts that are exact fit replacement parts.
- Throttle Sensors - The throttle sensor monitors the throttle position on your vehicle, and if this sensor goes bad, you might notice a surging or bucking in your engine. We carry replacement sensors like the throttle sensor, as well as other throttle parts.
- Radiators - The radiator holds all of the coolant that your engine needs to stay cool while running. A radiator that has a leak or has rusted out won't be able to hold coolant, resulting in an overheating engine. We carry cooling system parts for your Cadillac.
- Water Pumps - The water pump moves the coolant throughout your engine, and if the pump is bad, you can overheat. We carry water pumps, hoses and fans.
