Hummer Fan clutch setup

[Acesneights1]

Buy my extra pump !!!

:rof:
You know what...after the junk I just got from Advance, I may. Post some good pics of the vein side with a tape measure from the impellor to both ends of the veins. If it's not mismade like all the junk I have seen lately I will buy it. I'm gonna need one for the CUCV serp belt conversion.
If there is any question of what I am talking about read my Chinese junk WP's thread.

Will do

Hey if it's 4 bolt, no good. I'm looking for thread on for that one.

Just as a side note, I've removed the a/c condenser from 2 of my trucks. They can't hardly get up to operating temp even with old fan clutches. It made a huge difference getting them out of the air flow.

I believe that. That was why I pondered losing the Oil Cooler for an internal one.

Now here's a question. Is the air flow really so much better in the OBS(gmt-100) trucks that the condenser doesn't matter? Mine ran the same temp with or without the condenser installed, and doesn't seem to care if the A/C is running or not. Only difference i notice is a tad more boost if the big ol A6 is running. Can feel when i turn it off/on, but temp seems to stay the same.

Yes, the airflow on the 88-00 body-style is horrible through the stack. The design is too aerodynamic. This gets you good MPG unloaded but can't keep you cool loaded. Removing restrictions and better fans get results. The OBS doesn't need 'results'

I hate to resurrect an old thread but..... I have taken the plunge on this project for my 95 burb, found a fan blade on eBay, and a good used fan clutch as well (thanks chief for the part numbers). And managed to track down a 12 volt fan solenoid. The part number I found was 1059-06607-01 that's a kysor number and according to Borg Warner tech support it is the same one, if the part number ends in -02 it's 24v. I have a question about the serp pulley before I order. As per the posts by chief his part number is 12469472 and mascara lists it as Pulley water pump but there is another one listed as RCSK18221. Any hummer experts (hopefully chief ) that can help me complete the puzzle

Well I got my water pump pulley and bolts today and fan solenoid the clutch and fan arrive soon so will update when I get them installed, should be fairly straight forward as the hummer engines use all the same other pulleys as a civilian one

Any updates on this? I'm hoping you found a way to make it work so I can copy all your hard work!

 

[big blue dsl]

It is installed and working awesome! I was going to start a new thread when I get back from vacation with a bunch of pictures and a video of it working .....just have the a/c and temp switch to install. And I will post all the part numbers. Be aware though u will need a machinist to make it work....more soon

 

[Bullseye240]

Thanks. Can you PM me when you start the new thread as I don't check this a lot since my truyck is back in the state and I won't be back to it for a while.

I'm very interested in the new thread about the hummer fan clutch. Looking forward the the thread.

Thought i would post a pic of the geared fan assembly on the new Hmmvw for those who have not seen it.

 

[big blue dsl]

That's pretty cool, albeit not the one that I installed, I put the kysor hydraulic one on my truck

Do you have a part number for the temp sensor in the crossover pipe and the delay module? Thanks

Was there ever another thread started on this?

If You are looking for an affordable fan system mod, check with AK Diesel Driver. He put together a system that I would like to copy.

 

[dixiepc]

I'll look him up. I have several of the Humvee clutches and some of the other parts so I would like to get one of these setups working. Thanks

IIRC that Hummer fan clutch setup was supposed to be in the $12-1500 range
