21-5193 Power Steering Pump with Pulley for Honda Ridgeline - Reliable

In this review of the 21-5193 power steering pump with pulley, the bottom line is simple: this is a practical replacement for owners of V6 3.5L Honda Ridgeline models who need a direct-fit, budget-friendly pump to restore steering assist. The reviewer found it best suited to drivers replacing a leaking or failed OE pump who are comfortable following the manufacturer's installation notes, because the unit requires system flushing, new O-rings, and careful bleeding to avoid noise. Overall the pump delivers correct fit and acceptable performance when installed and bled correctly.

Key Features

• Direct replacement: Fits Honda Ridgeline V6 3.5L models 2006-2011 and matches OE part 56110-RJE-A01 for a straightforward swap.
• Pre-tested unit: Each pump is 100% tested before shipping, which reduces the chance of receiving a non-functional unit out of the box.
• Durable construction: Made from high-grade aluminum alloy with a corrosion-resistant finish to extend service life compared with some standard pumps.
• Integrated pulley: Includes the pulley for an easier installation and correct belt alignment when replacing the old assembly.
• Performance focus: Engineered to restore hydraulic assistance for smooth, responsive steering when the fluid circuit is clean and bled correctly.

Who It's For

This pump is aimed at Honda Ridgeline owners with a V6 3.5L Crew Cab Pickup from model years 2006-2011 who need a like-for-like replacement for a leaking or underperforming power assist pump. It is a good option for DIY mechanics and independent shops that will replace return line O-rings, flush the system, and follow the bleed procedure recommended by the maker.

Those who should look elsewhere include owners unwilling to perform or pay for proper flushing and bleeding, and anyone who insists on an OEM-branded part for warranty cohesion; also shoppers concerned about noise or intermittent pressure should evaluate customer feedback carefully before buying.

Pros & Cons

• Generally considered good value compared with alternatives.

Cons

• Mixed reports on long-term functionality and occasional noisy operation if air remains in the system.
