The Mapco 9639M is a remanufactured hydraulic power steering pump engineered to restore original power-assisted steering performance. Designed as a direct-fit replacement, this unit meets or exceeds original equipment specifications for smooth, reliable steering control.

Key Features:

• Remanufactured to OE specifications for reliable, like-new performance
• Hydraulic vane-type pump design delivers consistent fluid pressure to the steering gear

• Direct-fit replacement — no modifications required for proper installation

A failing power steering pump typically presents as a whining or groaning noise when turning the steering wheel, increased steering effort, or fluid leaks near the pump. Replacing the pump with a quality remanufactured unit like the 9639M restores full hydraulic assist and driving confidence. For best results, flush the power steering system and replace the fluid during installation.
