Power Steering Pump 21-5290 Fit for 2001-2004 Honda and Acura

In this review of the 21-5290 power steering pump, the bottom line is simple: it is a practical, budget-friendly replacement for owners of compatible Honda and Acura V6 models who need a direct-fit pump to restore steering assist. Our review finds the unit best suited to DIYers and professional installers who prioritize correct OE fit and durable construction over refinement; it installs cleanly and matches original dimensions, but some users report variable performance and occasional noise.

Key Features

• Vehicle Compatibility: Designed to replace factory pump numbers 21-5290 and equivalents, it fits specified Pilot, CL, TL and MDX V6 models for straightforward installation.
• Direct Fit Design: Precision-engineered to match original dimensions so it mounts and aligns with existing brackets and hoses without modification.
• Construction Materials: Built with corrosion-resistant aluminum and iron parts to handle engine-bay heat and resist long-term corrosion.
• Steering Assist Function: Restores hydraulic assist to reduce steering effort and improve maneuverability and long-drive comfort.
• Warranty Support: Comes with a one-year warranty for added peace of mind after installation and initial use.

Who It's For

This power steering pump is aimed at owners of 2003-2004 Honda Pilot 3.5L, 2001-2003 Acura CL 3.2L, 1999-2003 Acura TL 3.2L and 2001-2002 Acura MDX 3.5L who need a like-for-like replacement that follows OE dimensions. It is a sensible choice for independent mechanics and confident DIYers who can verify vehicle compatibility and install a pump using standard tools.

Those seeking a whisper-quiet premium unit or expecting flawless long-term performance regardless of prior system wear should look elsewhere; customer feedback indicates mixed reports on functionality and some noise issues, so vehicles with downstream steering rack or hose problems may need additional diagnosis first.
