The hose has been designed for use in the Ford Transit Custom model with the 2.0 EcoBlue engine, facilitating installation in place of the original component. Its precisely shaped geometry and connection points allow for:

• installation in original brackets and guides,
• proper routing within the engine bay,
• maintaining clearances with other components.

Such a precise fit minimizes the risk of stress, abrasion, and leaks that could occur when using components with universal geometry.

Product Characteristics and Application Benefits

As a Ford brand component, the heater water hose is constructed to withstand the demanding temperature and pressure conditions typical of modern diesel engine cooling systems. The use of this component allows for:

• maintaining correct coolant circulation in the heater core circuit,
• reducing the risk of leaks in critical sections of the system,
• maintaining stable engine operating temperature and efficient cabin heating.

This product comes from the used parts segment, offering a cost-effective alternative while maintaining the functionality required for daily operation of a commercial vehicle.
