Radiators for water coolant fluid
This OE Match Water Radiator Set includes both left and right water radiators - designed as direct-fit replacements for the original factory cooling cores on Porsche 996 (911) & 986 Boxster models. Together they form the central cooling system components responsible for controlling engine temperature and preventing overheating.
SET OF 2

Fits:
Porsche 996 C2 / C4 / GT3 1997 - 2005
Porsche 986 Boxster 1997 - 2004

The cooling system of the Porsche 996 and 986 is based on two radiators (left and right) that effectively remove heat from the engine coolant under all operating conditions, from everyday driving to dynamic use on the road.

Each radiator is engineered to match original Porsche specifications for:
•  Core dimensions and fin density
•  Mounting points and hose connections
•  Coolant flow capacity
•   Heat transfer performance

This OE Match radiator set delivers balanced cooling and thermal stability by replacing both cores at once, ensuring equal efficiency on each side of the system. Manufactured from high-quality materials with durable aluminium cores and corrosion-resistant tanks, these radiators offer long service life and effective heat rejection with reliable fitment.

Direct replacement for the original Porsche components, this set installs using the existing mounting brackets, hoses, and hardware, making it ideal for cooling system overhauls, radiator failure replacement, or preventative maintenance on higher-mile vehicles.

A failing radiator can lead to engine overheating, coolant loss, reduced performance, and even engine damage if left unaddressed. Symptoms such as rising temperature gauge readings, coolant leaks, or steam from the engine bay indicate a compromised cooling core. Replacing both radiators as a matched set ensures consistent cooling efficiency and balanced performance across the entire system.

Replace this radiator set if you notice:
•  Persistent engine overheating
•  Leaks or corrosion on radiator cores
•  Bent, dented, or clogged cooling fins
•  Reduced heater performance
•  After front-end collision or cooling system service
•  During routine coolant system overhaul

This product comes with 2 YEARS Warranty

The radiator’s main role is to remove heat from the engine coolant that carries thermal energy away from the engine block and cylinder head. Hot coolant flows into the radiator, where it travels through a series of fine tubes and cooling fins. Air passing through the radiator core (from vehicle motion and fans) absorbs the heat, lowering coolant temperature before it returns to the engine.

Proper heat rejection helps:
• Maintain optimal engine operating temperature
• Prevent overheating under everyday and high-load conditions
• Support fuel efficiency and emission control
• Preserve engine component durability and longevity

 What the Products Do

• Radiator: Dissipates heat from engine coolant to maintain safe operating temperatures.
  
• Coolant Hoses: Carry coolant between the radiator and engine, ensuring proper circulation under pressure.
  
• Mountings: Securely hold the radiator in place, preventing movement, vibration, and premature wear.

Together, they form a complete cooling solution that keeps your engine protected and performing as intended.

Symptoms of Failure

• Rising engine temperatures or overheating
• Coolant leaks around radiator or hose connections
• Bulging, cracked, or soft coolant hoses
• Rattling or loose radiator due to failed mounts
• Sweet coolant smell from the engine bay
• Low coolant levels requiring frequent top-ups

Common Reasons for Failure

• Heat & Pressure Cycles: Repeated expansion and contraction cause radiator and hoses to weaken over time.
  
• Material Aging: Rubber hoses harden or swell, while plastic mounts may crack.
  
• Coolant Quality: Old or contaminated coolant accelerates corrosion and internal damage.
  
• Vibration & Stress: Worn mounts allow radiator movement, leading to leaks and structural failure.

Why Replace as a Kit?

• Restores complete cooling system integrity in one service.
• Prevents breakdowns by addressing all common weak points at once.
• New mounts ensure secure fitment and reduced vibration.
• Protects against overheating and costly engine repairs.
• Saves labour costs compared to replacing components individually.       

Ideal For: Cooling system overhauls, resolving overheating or leaks, and preventive maintenance on performance-driven or high-mileage vehicles.

Kit contains a Mahle radiator and Original Porsche hoses and mountings

Radiator water fans. SET OF 2.
This package includes two radiator cooling fans - one for the left and one for the right side. Upgrading an aging cooling system by replacing both fans at once for consistent performance and longevity.

Fits:
Porsche 986 Boxster 1997 - 2004
Porsche 996 C2, C4, GT3 1998 - 2005

Diagram ref no 2.

The purpose of this radiator cooling fan is to draw air through the radiator and air conditioning condenser when the vehicle's speed is low - for example, when idling or in traffic - helping maintain the proper coolant and cooling system temperature. This keeps the engine cool and the air conditioning system operating efficiently.

Key benefits of paired replacement:
• Ensures symmetrical airflow and balanced cooling efficiency.
• Reduces load on each fan, potentially extending lifespan compared to a single fan doing all the work.
• Provides redundancy - if one fan fails, the second may help prevent immediate overheating during transit or cooldown.
• Simplifies maintenance by replacing both fans together, avoiding mismatched wear and preserving consistent airflow characteristics.

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.
