As engines age and operate under heat cycles and pressure, rubber hoses and coolant pipes can become soft, cracked, swollen, or restricted, leading to leaks, overheating, and reduced cooling performance. This comprehensive OE Match kit provides direct-fit replacements for the critical coolant lines between the radiator cores, coolant pump, thermostat housing, heater core, and engine block. Each component in the kit is manufactured to meet or exceed the original Porsche specification in hose inner diameter, bend geometry, wall thickness, and connection profile so that it installs cleanly into factory brackets and ports without modification. OE Match materials are chosen for long-term resistance to heat, coolant chemical exposure, and mechanical stress, ensuring durable performance throughout the life of the engine. This kit simplifies maintenance and repair by grouping all key radiator and coolant pipe replacements into one convenient solution, reducing parts hunting and ensuring that worn or deteriorated hoses do not compromise the cooling system’s integrity after other components (such as radiators or pumps) are serviced.
What This Kit Does:
The coolant and radiator pipes in this kit work together to:
- Carry coolant flow between the engine, thermostat, heater core, coolant pump, and radiator
- Maintain correct pressure and temperature balance across the cooling system
- Support reliable heat rejection through the radiator cores
- Prevent coolant loss and overheating due to brittle or collapsed hoses
- By matching OE geometry and fitment, these hoses help maintain efficient coolant circulation and stable operating temperatures during normal driving as well as spirited use.

Water Coolant Radiators – Efficient Cooling Performance for Porsche Engines
Water coolant radiators are the heart of your Porsche’s cooling system, responsible for maintaining the perfect balance between performance and engine temperature. These components dissipate heat from the coolant as it passes through the radiator core, ensuring your engine operates at peak efficiency while preventing overheating - whether you’re cruising through city streets or pushing hard on the track.
At Design911, we offer a comprehensive range of genuine and high-quality water coolant radiators for Porsche models including 911, Boxster, Cayman, Cayenne, Macan, Panamera and transaxle cars. Each radiator is precision-engineered to provide efficient heat exchange, corrosion resistance, and a perfect fit, ensuring long-lasting performance and reliability for every driving condition.
What Do Water Coolant Radiators Do?
Radiators are essential to your Porsche’s engine cooling
system. Their primary functions include:
- Transferring
heat from the coolant to the surrounding air.
- Regulating
coolant temperature to prevent engine overheating.
- Supporting
overall thermal balance for performance and emissions efficiency.
- Enhancing reliability by maintaining optimal operating temperatures in all climates.
By efficiently dissipating heat, radiators protect your engine, prevent premature wear, and maintain consistent performance under pressure.
Why Do Radiators Fail?
Despite being built for endurance, radiators experience
constant thermal stress, exposure to pressure, and environmental elements that
can lead to failure. Common causes include:
- Corrosion
or rust due to contaminated or old coolant.
- Leaks
from cracked tanks, damaged cores, or failing seals.
- Blockages
caused by debris or scale build-up inside coolant passages.
- Physical
damage from road debris or stone impacts.
- Coolant contamination from oil or combustion residue.
Symptoms of radiator failure include overheating, coolant loss, visible leaks, or fluctuating temperature readings.
Why Replace a Faulty Radiator?
A damaged or inefficient radiator compromises your Porsche’s cooling system, risking overheating and potential engine damage. Replacing your radiator with a high-quality, manufacturer-standard unit ensures optimal cooling efficiency, reliability, and peace of mind.
Benefits of replacement include:
Restored
cooling efficiency and heat dissipation.
Prevention
of engine overheating and coolant loss.
Enhanced
vehicle performance and fuel economy.
Durable,
corrosion-resistant materials for long service life.
All radiators in our range are designed using premium aluminium cores, precision welds, and reinforced end tanks to ensure excellent cooling capacity, leak prevention, and long-term reliability — perfect for both standard and high-performance Porsche applications.
