Detailed Description

When a power steering reservoir cracks or leaks, fluid loss can lead to pump cavitation and run-dry damage. This URO replacement reservoir is engineered to match OE dimensions and mounting requirements, making it a practical choice for Jaguar XK8, Jaguar XKR, and Jaguar XJ8 applications. The heat- and oil-resistant plastic tank is built to handle engine-bay temperatures and pump pulsation while maintaining the correct clearance and factory-style layout. Part number MJF4000AA is also referenced as URO-011734 for the same application.

What It Helps Fix

• Power steering fluid leaks from a cracked reservoir
• Low-fluid conditions that can cause pump cavitation
• Run-dry damage to the power steering pump
• Loss of steering assist from fluid starvation
• Fitment issues caused by a warped or damaged OE tank

Installation Notes and Tips

Verify reservoir routing, hose condition, and cap sealing surfaces before installation. Transfer fluid only after confirming the system is clean and free of contamination. This reservoir is listed for 1997-2006 Jaguar XK8, 2000-2006 Jaguar XKR, and 1998-2002 Jaguar XJ8 applications.

Quality Assurance
