This hose serves as the top supply line in the cooling system, carrying engine coolant from the engine to the radiator (or between key cooling components) under pressure. It ensures reliable coolant flow and temperature management so the engine stays within its optimal operating range.
Fitment / Position on Car
• Installed on: Engine cooling system, as the upper supply hose
• Location: Between the engine’s outlet and the radiator inlet / supply path in the cooling circuit
• Role: Helps carry hot coolant out of the engine toward the radiator’s heat exchange core
Coolant hoses are exposed to heat, pressure, and vibration every time the engine runs. Over time, these stresses can cause hoses to crack, soften, or leak - potentially leading to overheating and engine damage. Installing a genuine Porsche OE hose like the 95810640200 ensures correct material and fit quality, preserving engine cooling performance and system reliability exactly as Porsche intended.

What This Product Does:
- Supplies coolant to critical cooling system components
- Maintains proper coolant circulation
- Supports heat transfer and temperature regulation
- Helps prevent overheating by ensuring steady coolant flow
- Contributes to overall cooling system efficiency
Symptoms Of Wear Or Failure:
- Coolant leaks in the engine bay or under the vehicle
- Low coolant warning light
- Frequent coolant top-offs
- Engine overheating or rising temperature gauge
- Sweet coolant smell from the engine compartment
- Steam from under the hood in severe cases
- Cracks, splits, or dry rot on the hose surface
- Bulging or swelling due to internal weakening
- Soft, spongy, or brittle hose texture
- Coolant residue or dampness around hose clamps or fittings
- Replacing a worn top coolant supply hose is important because it ensures coolant is delivered properly throughout the engine cooling system. Over time, heat and pressure can weaken the hose, leading to cracks, leaks, or sudden failure.
- If the hose fails, coolant loss can reduce circulation and cause the engine to overheat, potentially leading to serious and costly engine damage. Even small leaks can lower coolant levels and reduce cooling efficiency.
- Installing a new hose helps prevent leaks, restores reliable coolant flow, and protects the engine by maintaining proper cooling system performance.

Radiator Top & Bottom Hoses – Reliable Cooling for Porsche Performance
Radiator top and bottom hoses are vital components of your Porsche’s cooling system, responsible for transporting coolant between the radiator and the engine. The top hose carries hot coolant from the engine to the radiator for cooling, while the bottom hose returns the cooled fluid back to the engine, maintaining optimal operating temperatures for performance, efficiency, and reliability.
At Design911, we offer a full range of genuine and manufacturer-quality radiator top and bottom hoses for Porsche models including 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Each hose is precision-engineered for perfect fitment, high pressure tolerance, and exceptional heat resistance — ensuring reliable cooling under the most demanding driving conditions.
What Do Radiator Top and Bottom Hoses Do?
Coolant hoses are the lifelines of your Porsche’s cooling
system, and the radiator hoses perform the following key functions:
- Carry
coolant between the radiator and the engine.
- Regulate
engine temperature for consistent performance.
- Maintain
coolant pressure throughout the cooling circuit.
- Prevent overheating by ensuring efficient heat transfer.
Both the top and bottom hoses are designed to withstand high heat, vibration, and coolant pressure, providing dependable performance in every driving scenario.
Why Do Radiator Hoses Fail?
Over time, radiator hoses deteriorate due to heat, pressure,
and exposure to coolant. Common causes of hose failure include:
- Rubber
cracking or hardening from continuous heat cycles.
- Swelling
or soft spots due to coolant chemical breakdown.
- Leaks
at hose ends or clamps from pressure loss.
- Abrasion
damage caused by engine vibration or contact.
- Age-related material fatigue, especially in older vehicles.
Symptoms of hose failure include coolant leaks, visible cracks or bulges, fluctuating engine temperature, or a noticeable coolant smell in the engine bay.
Why Replace Faulty Radiator Hoses?
A leaking or weakened radiator hose can lead to overheating, coolant loss, and potential engine damage. Replacing these hoses as part of routine maintenance ensures consistent cooling performance and reliability.
Benefits of replacement include:
- Restored coolant flow and temperature stability.
- Prevention of leaks and overheating.
- Improved cooling system pressure and performance.
- Manufacturer-quality materials for long-term durability.
All radiator hoses in this range are made using reinforced, high-grade rubber and polymer compounds, designed to meet or exceed factory specifications for heat resistance, flexibility, and longevity.
