Fan Relay kit
A question about fan relay kits, I notice that there are different temp sensors offered that turn the fan on & off.
- If I run a 185 degree thermostat, what temp on & off do I need the fan to operate?
- What location do I mount/install the temp sensor?

You want to run the sensor where the temperature will be most accurate. You can use a thermal laser sensor to determine that. Typically in the head or intake manifold or whichever one has a port for a temp sender. You can also buy a connected that you insert inline in your radiator hose with a fitting for a temp sensor.
with a 185* thermostat 195* - 210* will work. I prefer the lower end myself. A 195* sender will shut off the fans around 185*. Yiu dint want the operating temp too low....
here is is a pretty good link with some good tips.

My pleasure. Although I am new to these old trucks and to Fords, my chevy has taken me around the block a few times and when I have things that cross over I try to share what I can!
If you haven't already considered an aluminum radiator you might. I think it does more for cooling than electric fans. In my Camaro I tried them and found a stock clutch fan with the stock shroud cooled better with an aluminum radiator than the electric fans did, but everyone has their own experience.
Let us know how it works out!
