My fan clutch finally went so I am installing my electric fan today. One question for all you guys out there with electric fans is where did you mount the temp sensor to trigger the fan on? Im using a painless wiring kit and a 3.8L fan, I just have no idea where to put the sensor, Im hoping to find a plug into a water passage in the head/block since it doesnt look like theres enough room to be tapping into the thermostat housing, plus the metal looks to thin. Thanks guys!

 

My thermo bulb is inserted in the upper driver side of the radiator.

 

Mine too (180 Black Magic anyhow), It looks like an M6 detonator (Silver metal Tube about 3/16 x 3 inch long).

 

Yah I didnt want to go the thermal bulb route so Im running an actual temp sender that needs to be stuck in the block somewhere. I might just get the attachment that fits in the upper rad hose and has a bung in it that i can thread the sensor into if I cant find anywhere else to put it.

 

I put the probe through the radiator right next to the top hose. The controller is on top of the fan shroud.
