About the Cardone Power Steering Pump Line
The Cardone Power Steering Pump line focuses on remanufactured components that meet or exceed OEM specifications. This product line emphasizes quality materials such as aluminum housings and precise attachment types to ensure proper fit and function. The 21-108 pump is part of this line, providing a reliable replacement option for BMW power steering systems requiring a press-on pulley and threaded outlet connections.
Product Details and Specifications
This remanufactured power steering pump features an aluminum housing for durability and heat dissipation. It uses a press-on pulley attachment type, so the original pulley must be reused or replaced separately. The pump inlet connects via a hose barb, while the outlet uses a threaded connection sized 16x1.5. The hose port type is washer style, ensuring a secure seal. This pump is designed for vehicles equipped with a remote reservoir system, although the reservoir and cap are not included. The package contains the hydraulic pump, an instruction sheet, and a sealing kit to assist with installation.
Common Applications and Issues Addressed
- Restores power assist in BMW 128i, 135i, 323i, 325i, 328i, 330i, and 335i models
- Eliminates whining noises caused by worn or contaminated pumps
- Resolves hard steering or inconsistent assist at idle or low RPM
- Addresses leaks or pressure loss due to pump wear or damage
- Improves steering response and fluid circulation in power steering systems
Installation Notes and Tips
When installing the Cardone 21-108 power steering pump, ensure the original pulley is compatible and properly pressed onto the pump shaft, as the pulley is not included. Use the provided sealing kit to prevent leaks at hose connections. Verify that the hose port type matches the vehicle’s washer-style fittings. Since mounting hardware is not included, retain or source the necessary bolts and brackets from the original assembly. Bleed the power steering system thoroughly after installation to avoid air pockets and ensure proper fluid flow.
Quality Assurance and Warranty
This Cardone remanufactured power steering pump undergoes rigorous testing to meet OEM standards for performance and durability. The aluminum housing and precise attachment types contribute to long service life. While specific warranty details are not provided here, Cardone products typically include a limited warranty covering defects in materials and workmanship. Consult product documentation or Cardone directly for exact warranty terms.
