The fan is moved back slightly from the stock position.
I installed a 4.0L fan from a '93 - '97 Explorer on my Jimmy today. A new clutch was installed on the fan. Does it move air? You bet! As soon as I turned on the engine, I noticed the extra air movement in the engine bay. I hope to notice the same difference with the A/C. A/C should run cooler. Especially in traffice and stop lights. The stock fan ran A/C near 75-80 degrees on a 95+ (100) degree day. Over the next few days, I'll watch A/C temperatures and report back.
