Opinions needed - Performed Optical Bump

the clutch I mentioned in my post above is showing 30mm x 1.5mm thread with a 36mm hex. I'll do a bit more spec matching to it and others to the 99+ 6.5 fan clutch and the above mentioned d-max clutch. if this one checks out, there is a wide range of vehicles it fits so the probability of finding one easily in the JY is good!
 
I suppose the thing I need to do is make the decision of using the 9 blade fan I already have from AK going with a thermal clutch or spending a little more and going to the electro style and another fan. being I don't really tow much, the only benefit I can see with the electro style is commanding it on with the AC. as my truck is now with the 6 blade fan and the modified clutch ( on at 180 deg ) it does fine for the AC and for keeping the engine cool. since I have to do the pump, it's best to get the HO pump, with that comes the change over from the bolt on to the spin on clutch that has to be changed.

If you changed the AC Delco balancer out every 100,000 miles you could get 500,000 miles out of the engine for the price of a fluid damper. That’s what has always kept me from buying one.

The AC Delco water pump normally cost over 200$ for the right one
 
Good morning guys, so it turns out I think I am going to do the ev style clutch with the cooling upgrade. on the fan controller the AK used on his rig, the Hayden 3651, uses the threaded port in the back of the passenger head. is there another port that can be used? I would like to use that port to install a coolant gauge for a true in the cab temp reading. I also saw a Hayden 3652 fan controller that has a temp probe that would go into the cooling stack. would this be a better option?
 
looking up the specs on the Hayden 3652, its a pre-set controller that is set "ON" at 185deg and "OFF" at 165deg. would this be ok since it's not adjustable?
 
I specifically didn't choose an in the stack probe as I wanted engine coolant temp at the source. I'm moving my probe to the block off plate as the port in the head fries the sender.

would the block off plate area work for mine since I have the single thermostat setup with the bypass hose to that block off?
 
just found an adjustable style controller with the probe. hayden 3647 (30amp) and 3654 (50amp) might be worth looking at too.
 
Go through AKDD thread about the electro viscous fan. All the PNs are in there. Most order them all right from RA.
Someone, dont remember who, they drilled and pipe tapped the thermostat crossover and said it works very well. I think that is right at the end of AKs thread.
 
I read through his thread. parts on order :) I'm still wondering how to route the wires through the fan shroud though without slicing n dicing it lol. I'm thinking of trying to run through where the shroud splits hoping the harness is long enough.
 
I ended up going with the probe style that was adjustable for now. only because I want to install a manual temp gauge in the head and knowing there isn't another port to use unless I drill and tap one. since we are planning another trip to Kerrville for more house maintenance for my step mom, I wanted to just probe the stack and keep it simple. since it's adjustable I will be able to set the temp lower if I need to, to overcome the air temp flowing through the stack while on the road. It also has an override circuit for the ac that I can tap into with a switch if needed.
 
I think too that it would be an advanced operation to replace the motor mounts first, before even beginning installation of the fan system.
Looking My truck over, the mounts have sagged and the 9 blade steel fan is a lot lower to the shroud than it is to the top.
Might wanna give Your fan to shroud a good looksee.
 
oh crap! I forgot about that! my version of Homer Simpson... DOH!! I'm sure mine are sagging lol I did have the 9 blade fan I got from AK installed for a short time and it wasn't hitting the shroud. maybe just maybe (fingers crossed) it will clear and I can plan another weekend to do the mounts!

I've been wanting to look into the poly mounts but I'm curious as to how much noise and vibration those will through into the cab.

Very little noise and vibration difference between the two types of mounts, but you will notice that the engine doesn't sag or become offset over time with the polyurethane, unlike the rubber mounts that degrade/tear, especially important when running the better fan blade and/or CAC piping.
