OK, I've upgraded my alternator and picked out a 14" PermaCool high preformance electric cooling fan. Question: How have people addressed installing the thermal sensor for controlling the electric fan? I want to use a sensor to get the benifit of not running the fan when it's not needed. It seems there are 3 kinds of aftermarket thermal sensors:
1) A universal "button" type that just mounts to something hot (radiator, block, etc.) to make a thermal measurment.
2) There is a "probe" type that gets stuck in the radiator fins.
3) There are threaded versions that screw into the engine.
The first two types don't seem to be that accurate, but I guess if an adjustable controller is used this can be compensated for. The threaded type seems to be most accurate and consistant. Has anyone out there installed a thermal sensor to control an electric cooling fan? If so, what did you use and how did it work out for you?
