• EPDM construction resists engine heat, ozone, and electrolysis-related breakdown
• Temperature rated from -40°F to 275°F (-40°C to 135°C)
• Working pressure rating: 17
• Direct replacement for select Jaguar heater hose applications
• URO MJB6720AC cross-references URO-006375 and 117 26123 738

Detailed Description

URO MJB6720AC is an HVAC heater hose designed for the water valve to water pump circuit on 1997-2006 Jaguar XK8 and 2000-2006 Jaguar XKR models. The molded profile supports OE-style routing, which helps preserve factory hose alignment and simplifies replacement in tight engine compartments. For buyers searching for a Jaguar XK8 heater hose or Jaguar XKR heater hose replacement, this part number provides a direct-fit solution built around the original hose shape.

The EPDM rubber construction is selected for durability in cooling-system service. It resists heat, ozone exposure, and ECD-related deterioration, which is important in applications where electrical activity can contribute to rubber breakdown from the inside out. MJB6720AC is a practical choice when replacing a worn or damaged heater hose on Jaguar XK8 and XKR vehicles.

What This Part Helps Address

• Coolant seepage from a cracked or aged heater hose
• Softening or swelling caused by heat exposure
• Routing issues from a hose that no longer matches OE shape
• Rubber deterioration linked to electrochemical degradation
• Service replacement for the water valve to water pump hose path

Installation Notes and Tips

Confirm the hose routing against the original part before installation. Inspect adjoining clamps, fittings, and nearby coolant components for wear, corrosion, or residue that could indicate a broader cooling-system issue. After installation, refill and bleed the cooling system according to Jaguar service procedures and check for leaks at operating temperature.

Fits 1997-2006 Jaguar XK8, N/A, water valve to water pump. Fits 2000-2006 Jaguar XKR, N/A, water valve to water pump.

Quality Assurance

URO MJB6720AC is backed by a 24-month unlimited mileage warranty. The hose is molded for OE-style fitment and built from EPDM material to support long-term service in the HVAC and cooling system.
