What This Product Does
The electrically driven fan supplies airflow through the radiator, helping it release heat from the engine coolant. It is a cooling-system fan, not the coolant radiator itself.
Functions
- Provides airflow through the radiator.
- Assists coolant heat dissipation.
- Supports control of engine operating temperature.
Symptoms of Fault
Increasing engine temperature or overheating in slow traffic can indicate a cooling-system problem. These symptoms do not identify the fan alone as the cause; radiator condition, coolant circulation and associated electrical components should also be assessed.
Why Replacement Matters
Replacing a confirmed faulty fan restores its role in radiator airflow. Cooling faults require attention because continued overheating can damage the engine. Correct application is important: similar-looking components may differ by engine, production cut-off or climatic specification.
FAQs
- How should I confirm compatibility?
Compare reference 95562413500 with the original component and check the engine, chassis cut-off and option codes supplied above. - Does overheating prove the fan needs replacement?
No. Establish the cause before replacing parts, as several cooling-system faults can produce similar symptoms.

The Series Resistor (OEM Part Number 996.616.101.00) is an essential component in the cooling system of Porsche 986 Boxster and 996 Carrera models. It controls the speed of the auxiliary radiator fan, allowing for both low and high-speed operation to keep your engine running at optimal temperatures.
Fits:
Porsche 986 Boxster 1997 - 2004
Porsche 996 C2 / C4 / C4S 1998 - 2005
Porsche 996 GT3 / GT3 RS 1999 - 2005
Diagram Ref No 4.
Why Replace Your Series Resistor?
Over time, heat and wear can cause the resistor to fail, leading to:
• Low-Speed Fan Failure: The fan may stop operating at low speeds, causing the engine temperature to rise.
• Erratic Fan Operation: The fan could run intermittently or at incorrect speeds, reducing cooling efficiency.
• Risk of Overheating: Poor cooling can result in engine overheating, potentially damaging critical components.
Common Symptoms of a Failing Resistor
• Fan Speed Issues: One fan may only operate at high speed, indicating a faulty resistor.
• Complete Fan Failure: In some cases, the fan may not activate at all.
• Persistent Engine Heat: Consistently high engine temperatures can signal a failing resistor.
Replacing a worn or damaged series resistor ensures your Porsche maintains proper cooling performance and protects your engine from overheating.

Radiator fluid, or coolant, is the most important part of your car's cooling system, which protects your engine from overheating. Low coolant can lead to a breakdown and expensive repairs.
The radiator is one of the principal components of the engine cooling system. Hot coolant leaving the engine passes through the radiator's internal channels, where heat is transferred through the radiator core and dissipated into the surrounding airflow. The cooled fluid then continues through the cooling circuit to help maintain the engine within its intended operating temperature range.
Porsche cooling systems operate under demanding conditions, and the radiator must withstand constant thermal cycling, cooling-system pressure, road debris and environmental contamination. Over time, the core can become damaged or restricted, while corrosion, deteriorated joints or physical impact can cause coolant leaks.
A failing radiator can reduce the cooling system's ability to control engine temperature and may eventually result in coolant loss or overheating. Replacing a damaged, leaking or inefficient unit with this OE Match Radiator helps restore cooling performance and protect the engine from excessive temperatures.

What This Product Does:
Symptoms Of Wear Or Failure:
Why Replacement Matters:
- The radiator is responsible for releasing a substantial amount of the heat absorbed by the engine coolant.
- If its ability to dissipate heat is reduced, coolant may return to the engine at a higher temperature than intended. If the radiator also leaks, the cooling system may gradually lose coolant and eventually become unable to control engine temperature effectively.
- Replacing a defective radiator before severe overheating occurs can prevent substantially more expensive repairs.

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

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

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
