Detailed Description
SKAP913050 is a replacement secondary air injection pump for the air injection system used on select 2004-2005 GM vehicles. This part is intended for applications where the factory pump has failed, causing reduced secondary air flow during startup and emissions-related drivability concerns. It fits 2004-2005 Buick Rainier, 2004-2005 Chevrolet Trailblazer, 2004-2005 Chevrolet Trailblazer EXT, 2004-2005 GMC Envoy, 2004-2005 GMC Envoy XL, 2004-2005 GMC Envoy XUV, and 2004 Oldsmobile Bravada.

What It Is Used For

- Addressing emissions system fault codes related to air injection

Installation Notes and Tips
Verify the vehicle year, make, model, and emissions system configuration before ordering. Compare the original pump connector, mounting points, and hose routing to confirm match-up with the existing setup. Professional installation is recommended for emissions system repairs, and related fault codes should be cleared after repair.
