Diagram ref no 15
This part supersedes / cross-references the earlier Porsche numbers: 99710665102, 99710665103
What This Part Does / Functions
• Carries coolant within the front radiator cooling circuit
• Connects into the front coolant pipework and radiator feed system
• Helps maintain correct coolant flow between the engine and front radiators
• Supports stable engine operating temperature
• Helps prevent coolant restriction caused by aged, damaged or blocked pipework
• Provides correct OE Porsche shape, connection points and fitment
• Replaces a leaking, cracked, corroded or damaged original coolant pipe
• Supports reliable cooling system performance on high-performance 997 models.
Why Replace This Part?
The coolant pipe is exposed to heat cycles, pressure, coolant additives, road debris and age-related wear. Over time, the pipe or its connections can become brittle, corroded, cracked or start leaking. A failing coolant pipe may cause coolant loss, low coolant warnings, overheating or visible leaks around the front cooling system. Replacing it with a Genuine Porsche OE coolant intake pipe helps restore correct coolant flow and factory fitment. This is especially important on performance models such as the 997 Turbo and 997 GT3, where efficient cooling is essential for engine reliability.
When to Replace This Part
• If coolant is leaking from the front radiator pipework area
• If the pipe is cracked, damaged, corroded or distorted.
• If coolant loss or low coolant warnings are present
• During front radiator or cooling hose replacement
• During front-end cooling system overhaul
• If the pipe connection points are damaged or no longer seal correctly
• After accident damage or impact to the front cooling circuit
• When restoring the cooling system with correct OE Porsche parts.
Where It Fits on the Car
This part fits in the front coolant system / front radiator circuit. It is part of the coolant feed/intake pipework that connects the vehicle’s front cooling components and helps route coolant through the radiator system.

About Coolant Hoses - Centre Section
Coolant Hoses – Centre Section | Reliable Cooling for Porsche Performance
The centre section coolant hoses are vital components of your Porsche’s engine cooling system, responsible for circulating coolant between the front and rear of the vehicle. These hoses maintain consistent coolant flow through the radiator and engine, ensuring optimal temperature regulation and preventing overheating — essential for both performance and longevity.
At Design911, we supply a full range of genuine and high-quality coolant hoses in the centre section for Porsche models including 911, Boxster, Cayman. Each hose is engineered to deliver factory-accurate fitment, high heat resistance, and long-lasting durability under the extreme pressures of Porsche’s high-performance cooling systems.
What Do Centre Section Coolant Hoses Do?
Coolant hoses act as the lifelines of your Porsche’s cooling
system. The centre section hoses connect key parts of the cooling
circuit, helping to:
- Transfer
coolant between the engine, radiator, and water pump.
- Regulate
engine temperature during all driving conditions.
- Maintain
system pressure for consistent cooling performance.
- Prevent overheating and protect the engine from thermal stress.
Their design ensures smooth, efficient coolant flow — especially important in Porsche models with long mid- or rear-engine coolant routing systems.
Why Do Coolant Hoses Fail?
Over time, coolant hoses are exposed to constant pressure,
high temperatures, and fluid corrosion. This can lead to:
- Rubber degradation or cracking from heat cycling.
- Coolant leaks due to worn hose ends or clamps.
- Swelling or soft spots caused by chemical breakdown.
- Abrasion damage from contact with nearby components.
- Age-related hardening, reducing flexibility and sealing strength.
Common signs of hose failure include visible cracks, coolant puddles under the car, engine temperature fluctuations, or low coolant levels.
Why Replace Faulty Coolant Hoses?
A weakened or leaking coolant hose can quickly lead to overheating, engine damage, or complete coolant loss. Replacing worn hoses ensures your Porsche’s cooling system operates safely and efficiently.
Benefits of replacement include:
- Restored, leak-free coolant circulation.
- Improved temperature control and engine protection.
- Prevention of overheating and costly repairs.
- Manufacturer-quality construction and precision fit.
All hoses in this range are made from high-performance rubber compounds and reinforced materials, designed to meet exacting standards for flexibility, strength, and heat resistance.
