Common Steering Symptoms

• Whining or groaning while steering
• Heavy or inconsistent steering assist
• Fluid leakage around the pump or hose connections
• Foamy fluid caused by air entering the system
• Pulley noise or vibration

Similar symptoms may also be caused by low or incorrect fluid, leaking hoses, a restricted reservoir screen, trapped air, belt or tensioner problems, steering-rack faults, or damaged suspension components. Diagnose the complete system before replacing the pump.

Installation Notes

Professional installation is recommended. Confirm the correct fluid specification and inspect the reservoir, supply hose, pressure hose, return line, clamps, belt, tensioner, pulley, and steering rack. Flush contaminated fluid from the system according to Honda service procedures. Replace disturbed seals or O-rings with correctly specified parts. Do not run the pump dry. Fill and bleed the system using the proper procedure, then inspect for leaks, abnormal noise, foaming, belt tracking, and normal steering assist before road use.
