fitting electric fan to old 110

(1/2) > >>

Hi all, I am trying to fit an electric fan (borrowed from a Mondeo) to the rad on an 83 110.  rather than fit a manual switch to the dash I am looking for suggestions for fitting some kind of thermostat switch to automate it.  Am looking at the kenlowe option at the moment, does anyone have any alternate options please?

I use one of these from Merlin Motorsport.  Not the cheapest way of doing it, but I felt it was the best way to get control without faffing around, sticking things through the radiator, or trying to get a sensor to seal.

Hightower:
Tim,

Did you get the fixed or variable thermostat?

Thanks Tim,
How much did it cost?  I have ordered the part now hopefully it will do the biz.  I have got a thermostat with adjustable temp, but it wasn't as cheap as I would have liked.  On top of all the rest to get the money pit working.  But I think this is all I need now to be good on the road.  Looking at the pic, does the sensor fit around the top hose?

Oh and while I am here, the fan I am fitting is a dual type.  Should this be fitted in serial or parallel.  Any other tips as I have heard that some fans require quite a bit of juice to start up (up to 40 amps) should I use this type of wire to be safe?

V8MoneyPit:
Yes, there can be a peak in current draw. Make sure you are using cable and connectors of a suitable rating. I use a pair of Kenlowes and the lights dim as they kick in, then pick up again after a second or so.

Also, don't forget to wire in a switch so you can disable them for wading.
