RADKIT99606
Product Information
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

99662413500/2KIT
Product Information
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.

Product Information
Radiator for water coolant fluid (also known as Coolant radiator, Water radiator or Water coolant fluid cooler) is the backbone of a Porsche engine’s thermal management system. It dissipates heat from the engine’s water-based coolant, stabilising engine temperatures, preserving performance, efficiency, and long-term reliability.
Fits:
Porsche 986 Boxster 3.2L 2000 - 2004
Porsche 996 C2 / C4 / C4S / GT3 1998 - 2005
This product supersedes Porsche's old part numbers: 99610603750, 99610603751, 99610603752
Diagram Ref No 1.
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

About Water / Coolant Radiators
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.
