GMC Sierra Vacuum Pumps & Parts

The GMC Sierra, as well as its Chevy-badged sibling, the Silverado, is a full-size pickup truck, which is available in classic light-duty and heavy-duty configurations. Both trucks were officially released in 1998 and are successfully marketed up to these days. The first generation of the Sierra was based on the GMT800 platform, while the heavy-duty version featured a strengthened GMT880. In 2000, the automaker launched a new line, the C3 edition, which became an upscale version of the 1500 model. It came equipped with all-wheel drive and was powered by a 6.0 L 325-horsepower Vortec engine. Two years later, the nameplate was changed to the Sierra Denali.

If your Sierra has got a diesel engine, it certainly has a built-in vacuum pump, which operates a power brake booster and actuators of the HVAC system. It is driven directly by the camshaft or belt, depending on the engine configuration, and is a crucial component of the air intake system.
