^This. Though I do apologize for my response reading a bit sh1t, I was on an ipod 2 and had to write it twice. I also assumed the truck had ac.
I have had my fan off for 5 years now, it hasnt made my truck explode, and has been a good free mod. I didnt buy a switch to activate it or tuner, simply use the hvac switch to turn the fan on when i know the truck will be sitting. Seems to work just fine in ac or defrost. Left the ac on when i took it to smog. It passed in less than 10 minutes, but had no problem idling while I chatted for a half hour with the guy smogging it. If I had left the ac off, the truck would indeed have gotten very hot, very fast in the summer heat. So it requires planning to be free.
I wont make any claims of power since I have no dyno sheet to back it up. From the butt dyno *not scientific or guaranteed to be true.* The revs do drop a bit quicker between shifts once the iac is done doing what it does. Throttle response seems to be improved. Not anything too crazy, its still a slow truck. Also havent calculated mpg ever on the truck since new, so I cant comment on any improvement it may have made. I have enjoyed the slight difference it has made and I'd be sad to put it back on.
Threads are indeed reversed, dont know what serp or v-belt has to do with that. Right is loose, left is tight on the dtec in the ranger. I had too much b1tch in me to get it off myself, and needed a friend to hold the pulley still while i wrenched it off.
