Radiator hose bottom to water pump. Porsche 944 1985-91  ❭  94410623707

Lower radiator to water pump coolant hose.
Direct-fit replacement hose for the radiator lower hose on Porsche 944 road cars (models 1985 through 1991). 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:
Porsche 944 1985 - 1991

• 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.
