21-5441 Power Steering Pump with Pulley for Acura TL and Honda Pilot

In this review of the 21-5441 power steering pump with pulley, the bottom line is straightforward: this replacement suits owners of Acura TL and Honda Pilot V6 models who need a dependable, direct-fit steering pump. The reviewer focused on compatibility and build quality, and found the part to be a practical replacement for OE numbers 21-5441 and 56110RDAA01. For drivers dealing with noisy startup, hard steering, or a failing original pump, this unit promises a solid, cost-effective way to restore smooth steering feel without needing a remanufactured OEM core.

Key Features

• OE Compatibility: Matches replacement OE numbers including 21-5441 and 56110RDAA01 for straightforward fitment to specified Acura and Honda models.
• Direct Fit with Pulley: The pump arrives with the pulley installed, which reduces installation steps and helps ensure correct belt alignment.
• High-Quality Materials: Built from durable components intended to provide reliable operation and reduce pump noise at startup.
• Designed for V6 Engines: Specified for 3.2L and 3.5L V6 engines, so buyers of those engine variants get a purpose-matched replacement.
• Manufacturer Support: Supplied by a professional auto parts manufacturer and backed by customer support that responds to product-related issues.

Who It's For

This pump is best for owners of Acura TL 3.2L (2004-2008), Acura TL Type-S 3.5L (2007-2008), and Honda Pilot 3.5L (2005-2008) who need a one-to-one replacement part that cites the original equipment numbers. It appeals to DIY mechanics and independent shops that prefer a ready-to-install unit with the pulley already mounted.

Drivers who do not have one of the listed model years or engine types should look elsewhere, and buyers expecting a factory remanufactured core with OEM branding should note this is a high-quality aftermarket replacement rather than a new factory part.
