Description
Viscous coupling for Mercedes M116 and M117 V8 engines – OE-quality alternative
This viscous coupling has been specially selected for Mercedes-Benz models with the M116 and M117 eight-cylinder V8 engines. It is a high-quality reproduction in OE quality, developed for reliable and efficient control of the mechanical cooling fan. A technically correct and affordable alternative to the original OEM part.
The viscous coupling is suitable for various classic Mercedes models, including the W107, R107, C126, and W126, depending on the version and engine variant.
Efficient control of engine cooling
The viscous coupling regulates the drive power of the cooling fan based on the engine temperature. With a cold engine, the fan largely rotates freely, while as the temperature rises, more torque is automatically transmitted. This results in a stable operating temperature, effective cooling, and reduced unnecessary power loss.
Tuned to Mercedes V8 technology
This version is specifically designed for the thermal load of the M116 and M117 V8 engines. Internally, the clutch is filled with thermally stable silicone oil (PDMS), which ensures predictable and smooth operation, even in hot weather, stop-and-go traffic, or under prolonged load.
High-quality materials and OE-compliant construction
The viscous coupling housing is manufactured from die-cast aluminium, while the hub is made of steel for extra strength and durability. This choice of materials contributes to a long service life and reliable operation under various conditions.
The viscous coupling is supplied without a fan blade. The existing fan wheel can be easily transferred to the new coupling, ensuring trouble-free installation for the correct application.

Comparison numbers
For a simple check of applicability, the following OE comparison numbers are relevant:
1162000722, 1162000822, 1162001122, 1162000122, 1162000522, 1162000622
Protection of engine and riding comfort
A properly functioning viscous coupling prevents overheating, limits temperature fluctuations, and contributes to smooth and quiet engine operation. This increases driving comfort and extends the lifespan of the engine, cooling system, and related components.
Installation advice
Always check the engine variant (M116 or M117), vehicle application, and OE references before installation. Installation is preferably carried out by a specialized workshop. Since wear on a viscous coupling often occurs gradually, replacement is strongly recommended if in doubt.
