CARDONE Reman Power Steering Pump P/N:21-5391

Restore firm, low-effort power steering assist with the CARDONE Remanufactured Power Steering Pump 21-5391, a direct-fit replacement for the 2003-2008 Mazda 6. This pump generates the hydraulic pressure and fluid flow that drives the steering gear, so worn internals that cause hard steering, whining, or fluid leaks can be addressed by replacing the failed unit. CARDONE remanufactures the original core, scrutinizing the design and applying upgrades where applicable to build a more durable part than the original.

• Triple-tested internals: All critical components (campacs, spool valves, etc.) are triple-tested to help ensure reliable operation.
• Leak-resistant seals: Built with 100% new O-rings and premium-grade HNBR seals that do not break down at high temperatures like conventional seal material.
• Precision shafts: Shafts are surfaced to precise specifications to reduce premature seal wear and extend pump life.
• Calibrated relief valve: Supplied with a 100% tested and calibrated pressure relief valve, and the final assembly is computer-tested for pressure, bypass, fluid flow, valve operation, steering effort, and noise.

Every unit also undergoes a hydraulic efficiency test. See the Buyer's Guide tab to confirm the engine and application for your vehicle.
