Viscous Fan Kit – Toyota Fan to Chev / Holden V8 Petrol Engines

An efficient cooling system requires a good radiator, engine-driven fan and fan shroud, the GM and Nissan viscous coupled fans are not as effective as the Toyota type. Marks 4WD Adaptors now stock Toyota viscous couplings and fan blades, we also manufacture an adaptor that couples the Chev V8 or Holden V8 water pump and pulley to the Toyota viscous coupling and fan.

The Toyota fan is a staggered 7 blade fan that is 440mm in diameter. The length of this fan from the mounting face of the water pump pulley to the front of the fan blades is 100mm.
