Hello again Dblvenom. You can check to see if the new rad swich is working by taking it out and keeping the wires connected and holding the switch with vise grips, then using a propane torch you lightly aim the flame at the sensor end and within 10-20 seconds your fans should kick on, move the torch away from the switch as soon as the fans come on so you dont over heat and damage the switch. If it takes much longer torch time than about 20 seconds chance are tha rad switch is no good. I have experianced a bum new rad switch myself.
Hope this helps
Regards Carmine.
