This OE Match radiator return hose is a direct replacement part, manufactured to original specifications for precise fitment and durability. It is installed in the lower section of the cooling system, linking the radiator to the main return pipe or connecting pipe.
Sold each
Fits:
Porsche 986 Boxster 1998 - 2004
Diagram ref no 9
• Position: Lower radiator return hose (left or right side)
• Quantity: Sold individually (2 required per vehicle)
• It replaces earlier part numbers including 99610662701 and 99610662702.
The hose transports coolant from the radiator back into the cooling circuit, helping regulate engine temperature. It ensures that heat absorbed by the coolant is properly dissipated and recirculated through the system.
A properly functioning hose is essential for maintaining stable engine temperatures and preventing overheating.
Over time, coolant hoses can become brittle, crack, or degrade due to heat and pressure. A failing hose can lead to coolant leaks, overheating, and potential engine damage. Replacing worn hoses ensures proper coolant flow, protects the engine, and maintains reliable cooling system performance.
When to replace
• Coolant leaks or visible hose damage
• Cracks, swelling, or soft spots in hose
• Engine overheating or temperature fluctuations
• During cooling system service or overhaul
• Preventative maintenance on ageing vehicles
