same experience here...my new Gates belt was fine for about 1500 miles, but as the belt wore in, it started squeeling...with the 2793/Explorer fan

Any belt issues running the 2793 and the 10 blade combo?

Besides the 10 blade fan not really aligning correctly (sits very far back from the fan shroud vs the 9 blade fan) the results were the same with the belt squeal.

I really think the OEM belt is the best choice since it fit tighter vs the aftermarket ones. The Dayco belt I have is slightly longer. I'd like to get my hands on a Goodyear Gatorback belt, but I don't want it to die like the Dayco since it cost almost double!

I wonder if you guys that are having belt problems have a worn belt tensioner?

I've put about 3000 miles on mine with no issues. I'm running a Dayco belt but I prefer Gates.

Chris - what is the exact set-up that you are running?

Fan (9 or 10 blade)?
Fan Clutch?

10 blade fan from a 93 Explorer in the junkyard and the Hayden 2793 Explorer fan clutch.

How many miles are on your tensioner?

I thought of the tensioner myself...80k and i need a 2 ft breaker bar to move the tensioner....I don't want to spend $60 on a replacement, spend the time doing it and still have the same issue. Gates and OEM belt both squeel, but if I turn on the A/C compressor...no squeel (but no power either, )

It's burning the belt up. The "Severe Duty" just seems like too much resistance for those of us that run above 3000rpms often. I'm just going back to the stock clutch & 5-blade for now...the overheating/heat soaking at idle is getting to me - coolant temps were up to 234 at 13,800 ft this weekend...stock gauge showed a fuzz over 210...and it wasn't 50 ambient....not cool. I walked through the junkyard last weekend...I noticed a lot of vehicles had engine driven puller fans, and pusher electric fans in front of the A/C condenser. That may be another alternative.
nope ... was busy with my next project.
(will get rid of all these 42RLE shifting issues, high underhood temps, A/C and overheating problems and OPDA nightmares all together )
off topic ... will keep you updated in another thread

Well I was getting some nasty squeals at anything above 3500RPM's and my new Dayco belt was trashed so I went ahead and removed it and went to Auto Zone and got a free replacement. I got home and put the new belt on and still had some squealing of a slightly different nature. I went ahead and replaced my belt tensioner with a new Dayco unit. Before I had the belt back on I spun the water pump pulley around to check it and sure enough it's making a nice little noise. I have no slop in the pulley, but I'm 99% the water pump bearing is on it's way out.

I went ahead and installed the new tensioner and belt and it no longer is squealing, but when I turn the engine off and stick my head out of the Jeep I can hear the water pump making that weird noise as the engine stops.

I'm pretty sure the Torq Flo Severe Duty fan clutch is what caused the water pump bearing to start going out since that was the setup that slipped the most at above 3,500RPM's. I've got a free $20.00 credit at Auto Zone so I was going to get a replacement water pump from them, but I was also looking at a water pump from FlowKooler which is said to help with low RPM cooling, but it sounds to me like it would stress out the rest of the cooling system like coolant hoses and the radiator itself.

On a side note if you replace the belt tensioner the Dayco model has a bolt that sits very very close to the timing cover. It does not touch, but it's to close for my liking!!!! I tried to re-use the OEM bolt, but the design is different and I couldn't get the pulley to tighten up properly. I'm going to run into town tomorrow and replace the bolt with a button head bolt which hopefully won't stick out like the one that came with the Dayco belt tensioner.

9-14-11 Update:

Well I swapped out the bolt & washer on the Dayco Belt Tensioner with a hex button head bolt today so no more concern about it rubbing a hole in my timing cover! It sits nice and out of the way now vs before. I also purchased a GMB Water Pump from Advanced for $31.00 after a $25.00 online discount. The pump has an all metal impeller and it looks more like an earlier 97-99 design without the plastic impeller.

I'm not going to tear into replacing the old pump until it gets worse. I might even change out the thermostat housing with a high flow model for $20.00 and replace the thermostat while I'm working on the cooling system.

Still running the original with 128K on it now. But just cause mine is ok at 128K does not mean yours is good @ 80k.

Derale makes a 6 blade steel fan in 17" and 18" and heavy duty fan clutches and their stuff is made in the USA. Pricey, but Might be worth testing considering their line of cooling products.

I'm considering moving to an eFan on my '02 4.0L....I have a brand new Hayden 2793 HD clutch, new Dorman 620-112, 9 blade fan. I've got about $90 bucks in the complete setup and I'll take $50 + shipping for it! I can send it as a complete unit if anyone is interested. I probably have 50 miles on the setup...it will come complete and ready to bolt up to your rig providing that yours uses the single nut water pump design!

Sorry, I'm out of the US right now and won't be back for about 5 weeks....

When this thread started out, I ordered the new 10 blade fan and Hayden clutch but with the 112 degree temps that we had here in Arizona, it was way too hot to be working under the hood of my TJ. Well, today was a pleasant 86 degrees so I accomplished a few things that I wanted to do as replacing the fan and clutch. Worked out real nice and clean without any problems. The "towel test" on the front grill verified that every thing is working as planned. I really didn't have any overheating problems prior as my 4.0L ran at a constant 210 degees. Hopefully it doesn't get any hotter now but we'll see what happens when our Arizona weather goes back up to 115. Great job on the first write up !
