# 21085355 Cooling Hose | Genuine Volvo Penta Part

🔧 Product Description

  

Genuine Volvo Penta Cooling Hose - Part Number: 21085355

  

A genuine Volvo Penta moulded engine-cooling hose used in the D13B-A MP cooling system. The hose is formed to follow the original routing around the D13 cooling and oil-cooler assembly, maintaining the specified bend radius and connection alignment without kinking or contacting adjacent components. It is a distinct hose from companion part 21085358 and must not be selected by visual similarity alone.

• Correct internal diameter and end geometry for the specified pipe connections

• Reinforced construction suitable for hot, pressurised engine coolant
