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 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

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
