Nope, you're still thinking of it wrong . It's like this!

Pretend the plastic yellow cap is the pulley.

Agreed, just got back from wheelin in the rocks for 4 hours with AC on and Jeep never turned off and never saw temp go over 210 which it is always at, It was 105 and 40% humidity, I was thinking of doing this mod but I will wait and see where this goes, under the hood the Jeep is totally stock.

Could be that you weren't running hot, or it could be what Unlimited04 was saying here:

my Scangauge II will show anywhere between 190-240° read directly off the ECU, but the dash gauge will always show 210 +/- a needle width. Once the temps get to ~260°, the ECU pegs the gauge over and trips a CEL.

So when somebody says their stock gauge doesn't move off 210, I believe em...but that doesn't mean thats the actual operating temp of the engine.
The temp and oil pressure gauges on the newer model Jeeps (not sure when it began. Kucklehead says 2004) are more or less dummy lights. They don't really give accurate real-time readings.

That makes some sence, I will check it this weekend with mt IR gun, my tranny guage never went over 200 degrees on some long vertical climbs and it stayed at 190 most of the time with tranny cooler. When I have towed quad trailer I have seen temp guage move and cool down over a few miles, so I think it works. BTW the needle did move width of needle either side of 210 and can hear fan clutch engage and disengage periodically. Hope this helps.

Has anyone tried using that water wetter stuff by Royal Purple or Redline to help lower their temps? I used it in one of my Land Rover's and it helped out some. Just thought I'd throw that out there to anyone trying to lower your engine temps.

I run 25% coolant+ 75% water+ and +1 bottle of water wetter= 110% But really like I said I live in the city in Arizona try being in stop in go traffic on the freeway when it is ACTUALLY 118 degrees out side air temp not including other cars not just what your car thermometer says. And I have never gone over about 212. But everyone is going to tell you its because my gauge doesn't work and not because my cooling system is in good shape.

Here are the parts I am using.
Dorman #620-112 9 blade 93 Explorer.

Imperial fan clutch 215146
Or 92 2733 is the base number for most brands. That is from a 86 Mustang 5.0

Mine is cooling great. But I will add the spacer tonight.

Theres a couple stretches of road I need to climb during the heat of the afternoon sun to know if either fan/clutch makes a true difference under heavy abuse.
one would think at some point (speed) air crossing the condenser/radiator would negate the fan's need to engauge/lock up. Anyone ever seen information on this?

I am collecting base line info before making the switch to the Explorer fan/clutch to compare and this was one of my questions in mind.
