Information
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.
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.

Information
Radiator for water coolant fluid
This radiator functions as the primary heat exchanger in the Porsche Panamera’s cooling system. It transfers heat from the hot engine coolant into the surrounding air, helping maintain stable engine operating temperatures. Efficient cooling supports power delivery, emission control, and engine longevity - especially under everyday driving and high-load conditions. A properly functioning radiator also reduces the risk of overheating, prevents needless stress on engine components, and contributes to consistent performance.
Fits:
Porsche 971.1 Panamera 2017 - 2020 with 'S' equipment (PR: A8F)
Porsche 971.1 Panamera 2017 - 2020 with 'turbo' equipment (PR: A8H)
Porsche 971.1 Panamera 2017 - 2020 Hybrid (PR:0K3) with 'Standard' equipment (PR:A8C)
Porsche 971.2 Panamera 2021 - 2023
Porsche 976 Panamera 2023 >>
Diagram Ref No 1
The radiator is the heart of the engine’s liquid cooling system, responsible for removing heat from the engine coolant before it returns to the engine. As hot coolant flows through the radiator’s core, heat is transferred to the air passing through the cooling fins, helping maintain ideal engine operating temperatures. Proper cooling prevents overheating, supports consistent performance, protects internal engine components from heat stress, and helps maintain fuel efficiency and emission control.
