Cardone 3R-231 Power Steering Reservoir

Power Steering Reservoir for Ford and Mercury

The Cardone Power Steering Reservoir, part number 3R-231, is a new remote-mounted replacement built to restore proper fluid storage and flow in the steering system. It is designed for vehicles where a clogged or cracked reservoir can be mistaken for a failing pump, including Ford Ranger, Ford Explorer, Ford Explorer Sport Trac, Ford Explorer Sport, and Mercury Mountaineer applications.

Key Features

• Fits remote-mounted power steering reservoir applications
• Designed to match O.E. fit, function, and performance
• Manufactured from O.E.-grade plastic for strength and durability
• 100% tested for leak-free performance
• Includes reservoir cap
• Resistant to cracking from engine compartment heat
• Integrated-filter designs maintain O.E.-level filtration efficiency

Product Details

Cardone Power Steering Reservoir 3R-231 is a stand-alone replacement for remote reservoir systems and can also be used during a full power steering pump service. The reservoir is white, cap included, and built to follow original equipment design so it installs in the same location and functions like the factory unit. This part cross-references Ford and Mercury OE number 7L5Z3A697B for the same application.

What It Helps Address

• Low or inconsistent power steering fluid supply
• Noise caused by aerated or foaming fluid
• Leaks from cracked reservoir bodies or hose tubes
• Debris in the fluid from reservoir or hose deterioration
• Misdiagnosis of reservoir-related issues as pump failure

Installation Notes and Tips

Compatible With 2001-2011 Ford Ranger, 2001-2005 Ford Explorer Sport Trac, 2001-2003 Ford Explorer Sport, 1997-2001 Ford Explorer, and 1998-2001 Mercury Mountaineer. The reservoir may be located on the firewall, inner fender, or near the pump depending on the vehicle. Inspect the return and outlet hoses, and bleed trapped air from the system after installation to reduce foaming and cavitation. If the fluid is dark, gray, or contains debris, service the hoses and fluid according to the vehicle-specific OE manual.

Quality Assurance

Each Cardone reservoir is 100% tested to verify fit and function before release. It is made from OE-grade material and follows the original design for consistent performance in Ford Ranger, Ford Explorer, and Mercury Mountaineer steering systems.
