Detailed Description

Built for the heater circuit, this URO HVAC heater hose connects the heater core to the water valve on compatible Jaguar XK8 and Jaguar XKR models. The molded design supports correct hose routing, which helps maintain the original underhood layout and simplifies replacement of a worn or damaged hose. URO MJA6739AC is made from durable EPDM material with resistance to heat, ozone, and electrochemical degradation, making it a practical OE-style service part for Jaguar cooling and HVAC repair.

This part cross-references URO-012000 for the same application.

Common Repair Issues

• Coolant seepage at the heater hose
• Cracked or hardened hose material from age and heat exposure
• Restricted heater flow caused by hose collapse or internal deterioration
• Incorrect hose routing after prior repair work
• Loss of cabin heat due to a damaged heater core-to-water-valve hose

Installation Notes and Tips

Verify the vehicle application before installation. This hose is listed for 1997-2006 Jaguar XK8 and 2000-2006 Jaguar XKR, heater core to water valve. Inspect adjacent coolant components, clamps, and connection points for wear before reassembly, and confirm the hose is routed to match the OE path.

Quality Assurance

URO MJA6739AC is backed by a 24-month unlimited mileage warranty. The hose is engineered for temperature extremes and uses ECD-resistant EPDM material to help maintain durability in demanding cooling-system service.
