Detailed Description

Cardone’s Power Steering Reservoir line is built as a direct replacement for the original remote reservoir used on select Mazda vehicles. Part number 3R-907 follows OE design, uses OE-grade material, and is tested to confirm fit and function before it leaves the factory. This reservoir is intended for drivers servicing a Mazda 3, Mazda 3 Sport, or Mazda 5 with a leaking, cracked, or internally restricted reservoir.

This part cross-references Mazda BP4L32690B for the same application. The reservoir is white, includes the cap, and is supplied as a new component for remote-mounted power steering systems.

What It Can Help Fix

• Power steering fluid leaks from a cracked reservoir body
• Foaming fluid caused by trapped air or restricted fluid return
• Noise related to low fluid level or poor reservoir flow
• Pressure loss caused by a clogged remote reservoir
• Heat-related plastic deterioration in the engine bay

Installation Notes and Tips

On these Mazda applications, the reservoir may be located on the firewall, inner fender, or near the pump depending on vehicle configuration. Inspect the outlet and return hoses for cracking, debris, or internal breakdown before installation. If the fluid is discolored or contaminated, service the system and bleed trapped air after replacement to reduce cavitation and noise.

Quality Assurance

Cardone manufactures this reservoir to OE fit, function, and performance standards and tests each unit for proper operation and leak resistance. The design uses OE-grade material and is built to match the filtration efficiency of OE units when equipped with an integrated filter.
