Product Information
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
Diagram ref no 8.
• 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.

About Water Pump and Ancillary Hoses
Water Pump & Ancillary Hoses – Essential Cooling Components for Porsche Performance
Water pump and ancillary hoses are key elements of your Porsche’s cooling system, ensuring efficient coolant circulation between the water pump, radiator, expansion tank, and engine block. These hoses deliver and regulate coolant flow, maintaining stable engine temperatures and preventing overheating under high-performance conditions.
At Design911, we stock a comprehensive range of genuine and manufacturer-quality water pump and ancillary hoses for Porsche models including transaxle, 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Each hose is designed for precise fitment, high temperature resistance, and long-term reliability — matching the quality and durability of the original factory components.
What Do Water Pump & Ancillary Hoses Do?
Water pump and ancillary hoses work together as part of the
cooling network to:
- Circulate
coolant through the engine, radiator, and water pump.
- Regulate
temperature for optimal engine efficiency and longevity.
- Maintain
coolant pressure and prevent system airlocks.
- Support auxiliary components such as heater cores and turbo cooling lines.
These hoses ensure consistent coolant flow throughout the system, enabling your Porsche to perform safely at high temperatures and speeds.
Why Do Water Pump and Ancillary Hoses Fail?
Over time, hoses are exposed to constant heat, vibration,
and chemical contact with coolant — factors that can lead to wear and failure.
Common causes include:
- Thermal
degradation from repeated heating and cooling cycles.
- Cracking
or hardening of rubber due to age or coolant additives.
- Leaks
at hose ends or clamps from loss of flexibility or pressure.
- Abrasion
or rubbing against surrounding components.
- Swelling or soft spots from internal coolant corrosion.
Symptoms of failure include coolant leaks, overheating, visible cracks, or the smell of coolant in the engine bay.
Why Replace Faulty Water Pump & Ancillary Hoses?
A leaking or degraded hose can cause serious engine damage by disrupting coolant circulation and leading to overheating. Replacing old or worn hoses ensures your Porsche’s cooling system functions efficiently and safely.
Benefits of replacement include:
- Restored coolant flow and system pressure.
- Prevention of leaks and overheating.
- Enhanced reliability and performance under load.
- Manufacturer-quality materials and factory-accurate fitment.
All hoses in this range are constructed from high-performance, reinforced rubber compounds that meet or exceed Porsche’s engineering standards, ensuring long-term durability, flexibility, and heat resistance.
