manufacture=HAYDEN PART NUMBER 2835 FAN CLUTCH 93-97 7.3 per hayden=Thermal Severe Duty Fan Clutch (2835) by HaydenŽ. Size: 7.4" D, 3.53" H, Rotation: Reverse, Drawing Type: D, 5/16-18 Hole (6) Bolt Nut Type, 6" Fan Bolt Circle Size, Pilot Diameter: 1 1/4-18 Right, Pilot Depth: 0.67", Fan Mount Size: 5" D, 1.22" H, 1.88" (48mm) HEX. Designed specifically for your vehicle, this thermal severe duty fan clutch provides better cooling and efficiently controls the fan, allowing it to spin only when needed. The product turns the fan 80-90% of the shaft speed when engaged and 20-30% of the shaft speed when disengaged.

 

I shopped around looking for the fan clutch, I found varying prices from $101-140 on rock auto,com plus shipping costs, and $175 at Oreilleys Auto Parts.

At BPD the Adapter is $55, and their clutch is $189 I believe.

Since I'm on somewhat of a time line I'm just going to get the package from BPD, I live in Phoenix so I'll just run up to the shop and pick it up there, saves me shipping costs anyway.

 

That Hayden looks interesting

 

I don't think this mod would work for me, in my colder climate, my fan hasn't really run since October and I just did 1600 km last week and I am pretty sure it was never on the whole time, temps from 15 f to above 60.

Can someone tell me how does this fan control go from 20% to the 90% what controls it and does anyone have a manual bypass to trigger for towing?

 

your stock fan turns all the time when its running, just not as loud so you cant hear it,if you never tow or live in cold climate like you it may never sound off. The mod fanclutch is a thermostaticly controled clutch, no wires no controls- a bi metelic strip and oil clutch operate this AUTOMATICLY, it may not be for everyone if not needed.

 

I'm still planning on doing this mod this coming week, but wondering if anyone has done this that live in the desert southwest hotter climate.

I'm in Phoenix so temps will be above 100, soon and over 110 here shortly, just wondering if anyone that has this mod can chime in on how it worked for them in this hot climate.

Thx...

 

Well, just finished putting this mod in, took it for a quick drive nothing too long, temp got to 190 and stayed, butits a cool night here in PHX, so the real test is tomorrow. Going to hook up he jeep to tow and take it for a run I will let you all know what happens.

 

So this mod keeps temps below 190??? And the mishimoto tstat keeps it above 200??? So I'm lost on this. I understand wanting to control temps. But the original equipment was all designed to work in unison. Iirc the Oreillys fan clutch is about 250 with a lifetime warranty. And a healthy truck doesn't need any special requirements no matter the climate or the load. Ive hauled many heavy loads all across the country in all climates and the stock system does just fine. That's my opinion,, and it's just an opinion.

 

Sorry should have been more clear, I had a Mishomotto t-stat 200 in, replaced it with a ford OEM 192.

On my recent test drive the coolant temp stayed in range o f the t-stat of 190.

My question on the earlier post of the Mishimotto t-stat was would it be a good combo to have this mod and a t-stat that opened at 200?

Anyway, pulled the mishimotto, will probably just keep the oem t-stat, being in PHX and hot most the year.

 

So got the mod in yesterday and did a small test drive on it, everything looked good then, but I wanted to test it a little better. So today I loaded up the back of it with some camping equipment, hooked up my YJ Jeep to flat tow it and headed out to the desert.

Temps were in the mid to high 80's here, and the altitude is 1800+/-. Towed the jeep about 26 miles in all, 20 miles were at an average of 45-50 mph, last leg was 60-65 mph. The route was all level, no hills or grades to pull on this outing.

highest temp at 45mph was 200, that was seen while accelerating and as soon as i stopped accelerating temp started to cool slightly 198-196.

worst case was when I towed at 60-65, again when I accelerated the temp came up, this time to 202, then once he truck was established at 65mph and acceleration wasn't needed, temp subsided to 200-198. BTW EOT was 207-209.

Overall not a big test but, crawl, walk, run right? Next test will be early April, we will definitely get some hills in on that one. Will keep you all post on the performance of this mod.

Hello Gothere,

Just wondering how the mod is working for you over the summer. I am in need of replacing my fan clutch and was wondering how this works in the summer heat?

thanks,
Brian

 

I have a BPD 6.0 to 7.3 Fan Clutch Adapter if anyone is interested. $40 shipped. PM me if interested. The setup didn't work for me.

Nice conversation about the temps from a direct hook up -- so, sorry to get the thread back to the OP question. Replacing the waterpump and just cannot get the nut loose on the clutch fan! of course -I first checked the vid from diesel Ron (RIP). I have a 2005 6.0. Is there any chance this is a reverse thread? I borrowed the tools from Advance, tried the chisel (although mine might be a little underpowered). I put the advance auto wrench on, PB Blaster, then slid a pickle fork over the wrench - near the clutch fan nut - and smacked the end of the pickle fork with a small sledge. Still no movement.

 

No it's not reverse thread. I have the gear wrench tool, and mine came off fairly easy. Don't know what to tell you.
