Dorman engineered this replacement to match the form, fit and function of the original equipment so you can swap it in without modifying mounting points or hoses. The pump is constructed from durable materials and has been try-on tested for reliable fitment across a range of Cadillac, Chevrolet and GMC models from 2015 through 2019. Always confirm fitment by entering your vehicle trim in the garage tool before purchasing.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this pump restore vacuum-operated systems?\u003c\/h3\u003e\n\u003cp\u003eThe 904-861 re-establishes consistent vacuum supply to components that rely on engine vacuum. By matching OEM dimensions and mounting locations, it reinstalls as a plug-and-play unit so vacuum lines and brackets reconnect without adjustment. That helps return normal operation to brake assist and other vacuum-dependent functions.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDirect-fit replacement matching original pump mounting and ports\u003c\/li\u003e\n\u003cli\u003eDurable housing resists wear for steady vacuum delivery\u003c\/li\u003e\n\u003cli\u003eTry-on tested to reduce installation fitment issues\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich vehicles is this Dorman pump compatible with?\u003c\/h3\u003e\n\u003cp\u003eThis pump is compatible with a range of GM full-size trucks and SUVs produced from 2015 through 2019.
