Detailed Description

URO MNC6721AB is a molded radiator coolant hose made to match the OE hose shape used on specific Jaguar cooling and heater connections. The EPDM rubber construction is selected for resistance to heat, ozone, and electrochemical degradation, helping the hose maintain integrity in demanding engine-bay conditions. For buyers searching for a Jaguar XJ8 coolant hose, Jaguar XJR heater hose, or a replacement hose for the Jaguar Vanden Plas electric water pump to heater circuit, this part number provides the correct fitment profile and molded routing.

This part cross-references URO-006444 and MNC6721AA for the same application.

Common Problems This Hose Can Address

• Coolant leaks from a cracked or aged hose
• Softening, swelling, or hardening from heat exposure
• Incorrect hose routing after prior repair work
• Fitment issues caused by a non-molded replacement hose
• Cooling-system service needs on Jaguar Vanden Plas, XJ8, or XJR models

Installation Notes and Tips

Verify the hose routing against the original part before installation, especially on the 1998-2003 Jaguar XJ8 application with the air conditioning pump connection and chassis range note. Inspect adjoining fittings, clamps, and nearby coolant components for wear or contamination before reassembly. Confirm the hose seats fully on both ends and that the routing does not place tension on the molded bends.

Quality Assurance

URO MNC6721AB is backed by a 24-month unlimited mileage warranty. The hose is engineered for temperature exposure from -40°F to 275°F and uses ECD-resistant EPDM material to help resist internal rubber breakdown from electrolysis.
