Radiator for Water Coolant Fluid, SET OF 2. Porsche 996 / Boxster 986 (OE Part No. 99610613151 / 99610613251)  ❭  RADKIT99606

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
