CARDONE Reman Power Steering Pump P/N:21-5415

Keep steering effort light and hydraulic assist consistent with the CARDONE Remanufactured Power Steering Pump (P/N 21-5415). It drops in as a direct-fit replacement for the 2004-2005 Acura TSX — see the Buyer's Guide tab for engine-level fitment.

This pump supplies pressurized fluid flow to the steering gear so the system can reduce the effort needed to turn the wheel. CARDONE remanufactures each unit to meet or exceed O.E. performance, scrutinizing the original design and applying upgrades where applicable for a more durable part.

• Triple-tested components: critical parts such as campacs and spool valves are triple-tested for reliability.
• New seals: built with 100% new O-rings and premium-grade HNBR seals that don't break down at high temperatures like conventional seal material.
• Precision shafts: surfaced to precise specifications to help eliminate premature seal wear and extend pump life.
• Calibrated relief valve: supplied with a 100% tested and calibrated pressure relief valve.

Final assembly is computer-tested to measure pressure, bypass, fluid flow, valve operation, steering effort and noise. Signs the original pump may need replacing include whining or groaning while turning, heavy or hard steering, and fluid leaks — diagnose the cause before replacing.
