Help your emissions system push fresh air into the exhaust during cold starts with the Dorman - OE Solutions Secondary Air Injection Pump, part number 306-053. It fits a range of GM vehicles, among them the 2012-2015 Chevrolet Equinox, 2011 Buick LaCrosse and 2012-2015 GMC Terrain. See the Buyer's Guide tab for the full list and engine details.
A secondary air injection pump forces outside air into the exhaust stream shortly after a cold start, which helps the catalytic converter reach operating temperature. If a leaking or internally failed pump is the cause of an inoperative secondary air system, this unit replaces it.
- Direct replacement: Designed to install and operate like the original pump on the listed applications.
- Replacement for a failed pump: A dependable choice when the factory pump leaks or stops working because of an internal component failure.
- Durable construction: Built from quality materials for reliable performance and durability.
- Trustworthy quality: Supported by Dorman's team of product experts in the United States and more than a century of automotive experience.
Signs this pump may need replacing include a check engine light with secondary air system codes, a pump that runs noisily or not at all at cold start, or visible leakage. Valves, hoses, relays and wiring are also part of the system, so diagnose the cause before replacing the pump.
