Replacement RH51040002 Power Steering Pump Without Reservoir - 1.8L 4-Cylinder

The Replacement RH51040002 is a brand-new, direct-fit hydraulic power steering pump designed for the Honda Civic equipped with the 1.8L 4-cylinder engine. This pump is sold without reservoir, allowing for direct swap of your existing reservoir onto the new unit.

Key Features:

• Direct OEM replacement — engineered to match original factory specifications for a precise, no-modification fit
• Brand new construction — not remanufactured or refurbished; built to meet or exceed OEM quality standards
• Without reservoir — reservoir is not included; reuse your existing reservoir
• 1.8L 4-cylinder fitment — designed specifically for the SOHC i-VTEC 1.8L (R18A1) engine application
• Restores steering performance — eliminates symptoms such as hard steering, whining/groaning noises, and fluid leaks associated with a worn or failing pump

The power steering pump pressurizes hydraulic fluid and circulates it through the steering system, providing the hydraulic assist that makes low-speed maneuvering and parking significantly easier. Over time, internal seals and components wear, leading to reduced pressure output, fluid leaks, or noise. Replacing the pump with a quality unit restores full hydraulic assist and steering response.
