It looks like the fan is about an inch bigger also? Might have to check clearance if you have a MML?

I like A-Zones parts look up. They have great pics of every part.

The 86 Mustang with a v8 uses the same fan as the 93 Explorer but with a bolt on fan clutch..........I bet it will work.

Ford bolts are a very common 6x1mm I believe. They use a 10mm socket to tighten and remove them.
One last question Chris, did you bolt the clutch to the fan then slide it in as a whole unit, or attach the clutch to the water pump then slide the fan in and attach? My boys are on the way home with the parts so this is going to happen tonight.

The one I bought is about 3/8 inch smaller than the Jeep fan

I pulled the fan and clutch out as an assy and back in as an assy. Never thought about taking them out seperatly.

Cool. I was comparing the info on NAPA's part look up. It showed the Ford fan at 7.23" and the Jeep fan at 6"

I know my fan is kinda tight after my tummy tuck. I hate moving the shroud around

I believe that is the diameter of the fan clutch. Both fans ar 18 inch + or- a smidgen. If the Jeep fan fits the Ford fan will.

My Jeep is all stock so we will see how you guys with MML and dropped transfercases fare.

Yeah you are right. I hate slow internet connections at work.

Any idea if this Ford clutch would be enough for the Jeep 7 blade fan? I was fortunate enough to snag a 7 blade (with a HD clutch) a few years ago. Now my only fear is the ability to replace that clutch when the current one wears out.

Chris,

Since you work at an A/C shop you could provide some cool facts for us.

Run both the stock fan setup and the Ford Explorer setup for 15 minutes each. Do it back to back so ambient temps are the same. Run the blower on high with the A/C on. Hook up your A/C system gauges and tell us what the high-side pressure is after the 15 minute tests. If the fan is pulling more air and cooling better then the pressure should drop showing that increased cooling.

Couple the pressure differences with a therometer reading stuck in the center duct would be very interesting.

There is a lot more to fans than just blade count. Pitch also plays a big role. It also depends on how far the pitch goes down the blade as the blade approaches the center or if the pitch is variable along the blade. The center is turning slower than the outside which creates turbulence or not depending on the pitch.

More blades and a curved tip are usually to decrease noise and more blades usually require more energy to spin them.

It will have to wait till were out of our busy season. Right now Im booked solid for 3 weeks.

I did check the temp out of the ducts. 58 with the stock Jeep fan and bolted clutch and 42 with the Ford fan and clutch @ idle.

Another test was an idle test. With the Jeep fan it would hit 230F if left idling a while. It was 105F the day I put the Ford parts on it. I let it idle with the AC on for 45 minutes. My mechanical guage and code reader both showed 207 after 45 min.

Did the explorer fan put any more load on the engine cruising down the highway, or does it feel the same as the factory fan? Just curious how much this might hurt the already poor fuel milege haha
