Information
Lower radiator to water pump coolant hose.
Direct-fit replacement hose for the radiator lower hose on Porsche 944 road cars (models 1985 through 1989). It connects the bottom outlet of the radiator to the water pump inlet, forming a critical part of the engine’s coolant circulation system. Precision-moulded to original shape and dimensions, this hose fits exactly as the factory part did - ensuring correct routing, secure sealing, and reliable coolant flow under pressure and high engine temperatures.
Fits:
• Application: Lower radiator hose — radiator bottom outlet → water pump inlet.
• Ideal Use Cases: Cooling system maintenance, hose replacement during service, overheating prevention, or when original hose shows wear, cracks or leaks.
Coolant hoses are subject to continuous heat cycling, coolant chemical exposure, and flexing from engine vibration. Over time the rubber can degrade - becoming brittle, soft, cracked, or swollen. A failing radiator hose may lead to:
• Coolant leaks - causing low coolant levels or visible drips under the car.
• Engine overheating - risking long-term engine damage or immediate breakdown.
• Loss of coolant pressure or air ingress - potentially reducing cooling system efficiency.
Using a new hose restores reliable coolant circulation, helps prevent leaks, supports stable engine temperature, and reduces the risk of costly engine overheating or damage.

Information
Water coolant bottom hose
This OE Match water coolant bottom hose is a direct replacement for the original Porsche lower radiator hose fitted to Porsche 955 Cayenne 3.2L V6 models produced between 2003 and 2006. It forms part of the engine cooling system and transfers coolant between the radiator and engine cooling circuit to help maintain correct operating temperature and cooling efficiency.
Fits:
Porsche 955 Cayenne 3.2L V6 2003 - 2006
Diagram ref no 1
The lower coolant hose transfers cooled coolant from the radiator back into the engine cooling system, helping maintain stable engine temperatures and efficient cooling system operation.
This hose is ideal for preventative cooling system maintenance, radiator servicing, or replacement during thermostat, water pump, or engine cooling repairs on Porsche 955 Cayenne V6 models.
Function
• Connects radiator to engine cooling circuit
• Transfers cooled coolant back to the engine
• Maintains stable engine operating temperature
• Supports efficient coolant circulation and pressure regulation
• Helps reduce risk of overheating and coolant loss
Cooling system hoses operate under constant heat, pressure, and vibration. Over time, hose material can deteriorate internally and externally, increasing the risk of leaks and cooling system pressure loss. A failed lower radiator hose may cause rapid coolant loss and engine overheating. Replacing worn coolant hoses helps maintain reliable cooling system performance and protects the engine from costly overheating damage.
When to replace
• Visible coolant leaks or staining
• Cracked, swollen, or brittle hose material
• Cooling system pressure loss
• Overheating or fluctuating coolant temperatures
• During radiator or thermostat replacement
• During preventative cooling system servicing
