Detailed Description

Cardone 32-2402M is a secondary air injection pump designed for emission control service on 2004-2005 Buick Rainier, Chevrolet Trailblazer and Trailblazer EXT, GMC Envoy, Envoy XL, and Envoy XUV, 2004-2005 Isuzu Ascender, 2005 Saab 9-7x, and 2004 Oldsmobile Bravada with a 90 degree inlet port. It is built to restore proper smog pump operation by delivering the air volume needed for the vehicle’s air injection system to function as intended. This part cross-references Chevrolet (e.g., 12574379) for the same application.

As part of the Cardone Smog Air Pump line, this remanufactured unit is assembled with application-specific internal components rather than generalized vane sizing. That approach helps maintain proper flow characteristics across the listed GM and Saab platforms, including the Buick Rainier and Chevrolet Trailblazer family. The result is a direct replacement option for drivers addressing emission system faults tied to pump output or pump failure.

What It Helps Fix

  • Secondary air injection pump failure codes
  • Insufficient air delivery during cold-start emissions operation
  • Noisy or worn pump bearings
  • Emission test failures related to smog pump performance
  • Fitment issues caused by damaged inlet or outlet components on replacement pumps

Installation Notes and Tips

Verify the vehicle has a 90 degree inlet port before ordering. Confirm the mounting location and 3-hole pattern against the original unit, and transfer any vehicle-specific connections not supplied with the pump. The pulley is not included, so reuse or source the correct pulley as needed. Follow the included instruction sheet and inspect the air injection plumbing for restrictions or leaks before installing the new pump.

Quality Assurance

Cardone remanufactures this pump with 100% unit testing, new carbon shoes and vanes, and high-temperature grease to support bearing life and consistent output. The design is intended to meet or exceed OEM performance expectations for the listed applications, including 2004-2005 Buick Rainier and Chevrolet Trailblazer fitments.
