Power Steering Pump 21-5290 Fits 1999-2004 TL CL MDX Pilot - Reliable

In this review the Power Steering Pump 21-5290 is judged by its fit, function, and durability for older Honda and Acura models. It is aimed at do-it-yourselfers and independent shops who need a straightforward replacement pump to restore proper steering assist. The single biggest reason to buy is its direct compatibility with several 3.2L and 3.5L models and replacement of OE numbers 56110-PGK-A01, 56110-P8E-A01 and 56110-PVF-A01, which means minimal modification and fast installation.

Key Features

• Direct Replacement: Replaces OE 56110-PGK-A01, 56110-P8E-A01 and 56110-PVF-A01 to match the original pump mounting and fluid ports for easier installation.
• Exact Fitment: Designed to fit 1999-2003 TL 3.2L, 2001-2003 CL 3.2L, 2001-2002 MDX 3.5L and 2003-2004 Pilot 3.5L, reducing compatibility guesswork.
• Durable Construction: Built from quality materials intended to resist leaks and wear that commonly affect older steering pumps.
• Solves Common Symptoms: Addresses leakage, hard-to-turn steering, and squealing or groaning noises that occur when an original pump fails.
• Customer Support: The seller offers a warranty response and email support within 24 hours for quality issues and fitment questions.

Who It's For

This pump is best for owners of late 1990s and early 2000s TL and CL sedans or early 2000s MDX and Pilot SUVs who need a like-for-like replacement without modifying hoses or brackets. It is a good choice for independent repair shops and home mechanics who prioritize a pump that matches original equipment numbers and restores steering assist quickly.

Those who should look elsewhere include owners of vehicles outside the listed year and engine combinations and buyers who require a branded dealer remanufactured unit with extended factory documentation. Also, if low noise is an absolute requirement, note that reports on noise are mixed and some units can run louder than stock.

Pros & Cons

Pros

• Fits the specified models closely, making installation straightforward for most mechanics.
• Customers report good functionality and no leakage after installation in many cases.
• Considered good value for money compared with sourcing a new dealer pump.
• Matches OE part numbers for easier parts cross reference and fitment confidence.

Cons

• Noise level is mixed in real-world use; some users report a louder pump than their original unit.
• Limited to the listed model years and engine sizes, so compatibility checking is essential before purchase.
