- Porsche 944 Turbo S 2.5L 8V 1988
Diagram ref no 11
As part of the 944 turbo’s cooling system, this hose must handle continuous heat, pressure and coolant flow. Over time, it becomes a common wear item that requires replacement to prevent leaks and overheating.
What This Coolant Hose Does
This hose transfers coolant between the radiator and the coolant console, forming an essential link in the cooling circuit.
It helps:
• Maintain consistent coolant flow through the engine
• Transfer heat away from the engine to the radiator
• Support stable engine operating temperatures
• Maintain system pressure and efficiency
• Ensure reliable cooling under all driving conditions
A properly functioning hose is essential for protecting the engine from overheating.
Why Coolant Hoses Fail
Cooling system hoses degrade over time due to heat, pressure and age.
Common causes include:
Heat cycling
Repeated heating and cooling causes the rubber to harden and crack.
Age-related deterioration
Original hoses on classic 944 models can become brittle after decades of use.
Internal weakening
Coolant exposure can degrade the internal lining of the hose.
Pressure stress
Cooling systems operate under pressure, which can cause weak hoses to fail.
Symptoms of a Failing Coolant Hose
• Coolant leaks under the vehicle
• Low coolant warning or frequent top-ups
• Visible cracks, swelling or soft spots on the hose
• Sweet coolant smell after driving
• Engine running hotter than normal
Replacing a worn hose prevents sudden failure and costly engine damage.
Why You May Need to Replace This Hose
Prevent Engine Overheating
Ensures proper coolant circulation and heat dissipation.
Fix Coolant Leaks
Restores system pressure and eliminates fluid loss.
Essential Maintenance for Classic Porsche Models
A common failure point on ageing Porsche 944 Turbo vehicles.

Turbo Coolant Hose - Console to Water Temperature Switch Housing
This water coolant hose is designed for the Porsche 944 Turbo and connects the water coolant console to the water temperature switch housing pipe. It plays an important role in maintaining proper coolant circulation and ensuring accurate temperature regulation within the engine.
Fits:
- Porsche 944 Turbo 2.5L 8V 1985-88
- Porsche 944 Turbo 2.5L 8V 1989-91
- Porsche 944 Turbo S 2.5L 8V 1988
Diagram ref no 26
As part of the 944 Turbo cooling system, this hose supports the flow of coolant through key engine components, helping maintain stable operating temperatures and ensuring the temperature sensor receives accurate readings.
What This Coolant Hose Does
This hose forms a connection between the coolant console and the water temperature switch housing, allowing coolant to circulate correctly through the system.
It helps:
• Maintain continuous coolant flow through critical engine
areas
• Support accurate temperature monitoring via the sensor housing
• Ensure stable engine operating temperatures
• Assist in proper cooling system pressure and efficiency
• Prevent overheating by maintaining circulation
A properly functioning hose ensures both cooling performance and accurate engine temperature readings.
Why Coolant Hoses Fail
Cooling system hoses are exposed to heat, pressure and age-related degradation.
Common causes include:
Heat cycling
Repeated expansion and contraction weakens the hose material.
Ageing rubber
Original hoses can become brittle and prone to cracking over time.
Coolant exposure
Internal surfaces degrade due to prolonged coolant contact.
Pressure stress
Cooling systems operate under pressure, accelerating wear in weak hoses.
Symptoms of a Failing Coolant Hose
• Coolant leaks near the engine or under the vehicle
• Low coolant levels or warning lights
• Visible cracks, swelling or soft spots
• Inconsistent or rising engine temperature readings
• Coolant smell after driving
Replacing a failing hose prevents coolant loss and ensures accurate temperature monitoring.

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.
