right my zed is still in many pieces and wont becoming back on the road for a few months, so im doing some wait saving whilst i change my turbos,

 

i've remover the air con radiator/ pump/ pulley/ and 90% of the hoses, (didn't realise how heavy it is!!!)

 

and i found the air con electric fan located between the oil cooler (or gearbox fluid cooler in some) and the water radiator

 

now heres the question how does the fan work? i have 3 wires coming out of it and i want to attach it to a switch(or direct to the ignition) so i can bin the viscous fan

 

any other suggestions for weight saving? (spare is gone), so is most of the boot... but i want to leave the interior alone...

The electric fan thats originally mointed to the aircon rad should in no way be used as a replacement for the Viscous fan. Its knowhere near man enough.

 

if you insist on going the electric fan route (and I dont reccomend it, they are inferior) then you will need the biggest fan you can that moves at least 2500cfm, preferably 3000cfm+ and have it mounted to the Radiator surface inside the engine bay where the viscous would normally be. You want it hooked up to a Temperature controller, most fan kits come with a controller.

 

Your looking at a couple of hundred quid for a setup that will handle the job.

 

You should also consider something like a SPAL PWMV, which is a programmable controller with warning facility should the fan fail. An aftermarket water temp gauge is also essenstial.

 

...or you can just stick to the better stock Viscous fan setup.
