Detailed Product Overview

URO MNC4400AC is an engine coolant reservoir engineered for Jaguar XJ8, XJR, and Vanden Plas models from 1998 through 2003. The plastic tank is shaped to match original mounting and connection points, helping maintain proper coolant expansion and recovery in the vehicle’s cooling system. With a built-in level sensor, included cap, and pressurized construction, this reservoir supports OE-style service replacement needs. The part number MNC4400AC is also referenced as URO-009460 for the same application.

This reservoir measures 6.15 inches long, 5.25 inches wide, and 4.55 inches high, with metric dimensions of 156.2 mm x 133.3 mm x 115.5 mm. It is designed for Jaguar cooling system service where a direct replacement reservoir is needed for the XJ8, XJR, or Vanden Plas.

Common Issues This Part Can Address

• Cracked or brittle coolant reservoir plastic
• Coolant leaks from the expansion tank body or seams
• Faulty reservoir level sensor readings
• Damaged or missing reservoir cap
• Cooling system pressure loss at the reservoir

Installation Notes and Tips

Verify the reservoir shape, sensor connection, and cap style against the original unit before installation. Transfer or reconnect all hoses and electrical connections carefully, and inspect the surrounding cooling system components for wear, contamination, or heat damage. After installation, refill and bleed the cooling system according to Jaguar service procedures to help prevent trapped air.

Quality Assurance

This URO coolant reservoir is factory pressure-tested and made from heat-resistant materials suited to the cooling system environment. It includes a 24 Month Unlimited Mileage Warranty.
