Information
Top Radiator Coolant Hose
This top radiator coolant hose is designed for the Porsche
955 Cayenne 3.2 litre V6 engine. It forms a key part of the engine cooling
system by carrying hot coolant from the engine to the radiator, where heat is
dissipated before the coolant is recirculated.

Maintaining proper coolant flow is essential for keeping engine temperatures stable and preventing overheating. A worn or failing radiator hose can lead to coolant leaks and reduced cooling efficiency.
What This Coolant Hose Does
The upper radiator hose connects the engine to the radiator and allows coolant to flow through the cooling system.
It helps:
• Transport hot coolant from the engine to the radiator
• Support efficient heat transfer and cooling
• Maintain consistent engine operating temperature
• Ensure proper circulation within the cooling system
Without a properly functioning hose, the cooling system cannot operate effectively, increasing the risk of overheating.
Why Radiator Hoses Fail
Cooling system hoses are exposed to constant heat, pressure and vibration. Over time, these conditions cause the rubber material to degrade.
Common causes of failure include:
Heat cycling
Repeated heating and cooling causes the hose to harden and crack.
Pressure stress
Cooling systems operate under pressure, which can weaken ageing hoses.
Coolant contamination
Old or degraded coolant can damage the internal structure of the hose.
Age-related wear
Over time, rubber hoses lose flexibility and become brittle.
Symptoms of a Failing Coolant Hose
• Coolant leaks in the engine bay
• Low coolant warning messages
• Visible cracks, bulging or soft spots on the hose
• Sweet coolant smell after driving
• Engine temperature running higher than normal
Replacing a worn hose prevents sudden failure and helps maintain reliable cooling system performance.
Why You May Need to Replace This Hose
Prevent Overheating
A healthy hose ensures proper coolant flow and protects the engine from
excessive heat.
Fix Coolant Leaks
Replacing a damaged hose resolves leaks and restores system pressure.
Maintain Engine Reliability
Consistent cooling is essential for long-term engine health.
Essential Maintenance Item
Cooling hoses are wear components that should be replaced as part of routine
maintenance.
Direct Fit Replacement
Part number 95510623900 is designed as a direct replacement for the original
Porsche upper radiator hose.
