Viscous Fan Adaptor to suit Chev / Holden to Nissan Patrol

The Nissan viscous coupled fan is very effective as the coupling when heated by the warm air from the radiator, virtually locks the fan directly to the water pump rapidly cooling the engine.

Marks 4WD Adaptors manufactures an adaptor kit that easily couples the Chevy and Holden V8 water pump and pulley to the Nissan viscous coupling and fan.

When cooling high-performance engines we have found that fitting a Toyota viscous coupling and fan proved to be superior compared to the Nissan type. Marks 4WD Adaptors now have a kit for the Toyota type that includes the fan, viscous coupling and the adaptor.
