Bosch K Hydraulic Power Steering Pump

The Bosch K Series hydraulic power steering pump line supplies the hydraulic pressure that makes steering light and responsive. It is a replacement for the original power steering pump (also called a PS pump or steering hydraulic pump). Bosch steering systems were formerly known as ZF Lenksysteme, and the pumps are built to original-equipment design rather than reverse engineered.

Key Features:

• OE-based design and specification, intended as a direct replacement for the original pump
• Mechanically driven hydraulic pump construction that delivers the pressure and flow the steering system needs
• Built with Bosch's steering system experience as an original-equipment supplier
• Tested to original specifications for steady steering feel and long service life
• Includes a pressure-limiting valve to protect the steering system, as found on Bosch steering pumps

A worn or leaking power steering pump can cause heavy steering, whining noises, or fluid loss. Replacing it with a Bosch pump restores smooth, consistent steering assist. Each pump in the line is identified by its own Bosch part number.
