BOSCH Power Steering Pump K S00 000 664

Whining noises when you turn the wheel, stiff steering at low speeds, or fluid leaks near the front of your engine bay are classic signs of power steering pump failure. The BOSCH K S00 000 664 addresses these issues directly, restoring precise, low-effort steering response.

Key Benefits of the BOSCH K S00 000 664 Power Steering Pump

Here’s what sets the BOSCH K S00 000 664 apart from a run-of-the-mill aftermarket pump:

• Durable materials — high-grade housing materials selected for strength and corrosion resistance for long-term reliability under continuous hydraulic load
• Restored steering precision — hydraulic pressure output matched to OE specifications for consistent, predictable steering feel at all speeds
• Straightforward installation — designed to bolt in using the factory mounting points and existing brackets, with no vehicle modification required
• Consistent pressure delivery — engineered to maintain OE-matched hydraulic pressure for smooth steering response across the entire speed range
• Leak-resistant construction — quality seals and gaskets designed to minimize the fluid seepage common in aging pumps
• Reduced steering effort — eliminates the heavy, stiff feel that develops as the original pump wears down

Applications & Use Cases

This power steering pump is suited for daily commuters, highway drivers, and anyone who relies on predictable, low-effort steering in stop-and-go traffic or tight parking maneuvers. Whether you’re navigating city streets, merging onto the highway, or parking in a tight garage, a properly functioning power steering pump makes every maneuver easier and safer. Replacing a failing pump promptly also helps protect other steering system components — a pump running low on pressure or contaminated with metal debris from internal wear can accelerate wear on the steering rack, hoses, and gearbox, turning a moderate repair into a much larger one.

For background on how power steering systems work, understanding the hydraulic circuit helps explain why a failing pump affects steering feel so directly. Our fitment data is cross-checked against professional sourcing standards consistent with ASE-certified technician standards.
