yep theres a guy on ebay i spoke to selling cvh to zetec turbo head adpator plates for the thermostat to bolt to you head and means you can keep the cvh top water hose

if your running the ofab ecu you will need to change to the cvh housing or run your fan on a on/off bodge switch

the zetec fan is controlled by the ecu from what i can work out so the ofab wont support it and if you putting it in a cvh car then the standard car loom/ fan loom wires up and powers the fan, much better way of doing it than running the fan of a switch in the car
