Series resistor. Porsche 986 Boxster / 996

Series Resistor for Porsche 986 Boxster & 996 Carrera (OEM ref number 996.616.101.00)

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.

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.
