That thing is so 



what did you use to trigger the fan on the Volvo? I have a volvo e-fan setup sitting in the garage.
I bought a switch that you stick through the rad fins at autozone.

Post #14 has the e-fan info and part number for that switch.
I was sketchy about it at first. Ran all summer without issue. Temp guage stays right where it usually does and the fan cycles on/off in traffic like it should. I have it right between the "bars" on the rad so as not to rub and secured with it's speed nut with a piece of foam to take up any vibration. Time will tell if it holds up or rubs the bars or who knows.
