The Commodore V6 engine is not normally fitted with an engine driven cooling fan; the engine PCM and the BCM controls an electric fan to maintain the engine temperature. This system is normally satisfactory in most conditions however if the vehicle is to be used in sand or heavy off road conditions during the summer months requiring the air conditioning to be used then the electric fans will most likely not do the job and will cause the engine to over heat. For this reason Marks 4WD Adaptors have now manufactured an engine driven fan.

Note: The engine driven fan has been tested on our company Toyota Bundera with great success. The vehicle was used in the sand dunes near Robe, South Australia during the summer of 2001 in temperatures reaching the high 30’s with the air conditioning running flat out. At the time no fan shroud was used however, we have since found that for the air conditioning to work properly in heavy traffic where the engine is idling for long periods of time a fan shroud is required.

As mentioned above a fan shroud is required for maximum cooling efficiency. For this reason Marks 4WD Adaptors now manufacture a universal fan shroud kit that can be used with Hilux/4Runner and Bundera V6 and V8 conversions. The fan shroud kit consists of a blank fan shroud (no hole cut out for the fan) and a rolled ring to fit around the fan (maximum fan diameter 400mm). Note: Two ring lengths are available 35mm and 75mm the short one is used in Commodore V6 and V8 to Hilux applications and the long one is used in Chevy V6 to Hilux and Commodore V6 and V8 to Bundera.
