Cardone 21-5382 Power Steering Pump

Remanufactured Power Steering Pump for OE Fit

Cardone 21-5382 is a remanufactured power steering pump built for OE fit and hydraulic performance. It is engineered for select Chevrolet Malibu, Pontiac G6, Saturn Aura, and Buick Rendezvous applications with a remote reservoir setup.

Key Features

• Remanufactured Original Equipment design for direct vehicle fit
• All critical components, including cam packs and spool valves, are triple-tested
• Computer-tested final assembly checks pressure, bypass, fluid flow, valve operation, steering effort, and noise
• 100% new O-rings and premium HNBR seals help resist leaks and high-temperature breakdown
• Shaft surfaces are restored to precise specifications to reduce premature seal wear
• Supplied with a tested and calibrated pressure relief valve
• Aluminum housing with O-ring hose port type
• Remote reservoir design; reservoir not included

Product Details

Cardone Power Steering Pump 21-5382 is remanufactured to meet or exceed original equipment performance standards. The pump is inspected for design improvements where applicable, then rebuilt with tested internal components and calibrated hydraulic controls for consistent steering assist. This part cross-references Buick 10356531 and Chevrolet/Pontiac 15859434 for the same application. It is a practical replacement for drivers searching for a 2004-2006 Buick Rendezvous power steering pump, a 2007-2009 Pontiac G6 power steering pump, a 2007-2009 Saturn Aura power steering pump, or a 2008-2012 Chevrolet Malibu power steering pump. Cardone 21-5382 is also a fitment-based search match for remote reservoir power steering pump replacement on these vehicles.

Common Problems This Pump Can Address

• Low or inconsistent power steering assist
• Whining or noisy pump operation
• Fluid leaks at worn seals or fittings
• Steering effort that changes with engine speed
• Poor hydraulic pressure or bypass performance

Installation Notes and Tips

Fits 2008-2012 Chevrolet Malibu, N/A; reservoir not included, in-line filter, OE fluid and system flush required for warranty. Fits 2007-2009 Pontiac G6, N/A; reservoir not included, in-line filter, OE fluid and system flush required for warranty. Fits 2007-2009 Saturn Aura, N/A; reservoir not included, in-line filter, OE fluid and system flush required for warranty. Fits 2004-2006 Buick Rendezvous, N/A; reservoir not included, in-line filter, OE fluid and system flush required for warranty.

Before installation, flush the system, bleed air from the hydraulic circuit, and inspect the pulley and fluid lines for wear or contamination. If the original pulley has a loose fit on the replacement shaft, replace the pulley. If assist only returns at higher engine rpm, inspect the flow control valve, spring, and system cleanliness.

Quality Assurance

Each unit undergoes hydraulic efficiency testing and final computer testing to verify pressure, bypass, fluid flow, valve operation, steering effort, and noise. CARDONE remanufacturing reduces the energy and raw material needed versus producing a new part, supporting a lower-waste repair process.
