Power Steering Pump 21-5442 Fit for Honda Pilot Odyssey Acura

Our review of the 21-5442 power steering pump looks at fit, build, and everyday performance. Designed for Honda Pilot and Odyssey V6 models and a wide range of Acura MDX years, this pump's single biggest selling point is its precise fit to original equipment dimensions, which makes replacement straightforward for DIYers and shops alike. The reviewer found the pump improves steering assist when it functions as intended, while noting mixed feedback on long-term quality and occasional noise reported by some owners.

Key Features

• Exact fit: Precision-engineered to match original dimensions so the unit installs without modification and aligns with factory mounting points.
• Wide compatibility: Covers 2005-2010 Honda Odyssey and 2005-2008 Honda Pilot V6 applications plus 2003-2013 Acura MDX variations, simplifying parts sourcing for these models.
• OE cross references: Replaces OE part numbers 21-5442, 56110-RGL-A03, 56110-PVJ-A01, and 56110-RYE-A02 to help ensure correct replacement.
• Materials: Constructed from corrosion-resistant aluminum and iron components to withstand engine-bay heat and moisture for longer service life.
• Steering assistance: Restores power assist to reduce steering effort and improves vehicle control and comfort on long drives.

Who It's For

The pump is best for owners of compatible Honda Pilot 3.5L, Honda Odyssey 3.5L, or Acura MDX 3.5L/3.7L models who need a direct-fit replacement and want a straightforward swap without custom work. It suits independent mechanics and confident DIY installers who can verify vehicle fitment against OE numbers before purchase.

Those seeking a return-to-new factory performance with an extended track record may want to consider OEM options or a remanufactured unit with a documented history, since customer feedback includes mixed reports on long-term durability and noise level.
