What is it on? You'll need to run thick enough wire to power the fan. Use a relay that is kicked on by an adjustable temperature sensor. So, what else do you want to know?
It is an '06 H3 (3.5 I5) and the fan causes a notable vibration and loss of power when it engages. I would also like to be able to disable it if going through a deep river.
That's the little Hummer? What engine do you have in there? I think it's the Vortec 3500? If so, it's basicaly a Colorado, maybe you can use a fan off that?
I know in my Tracker, I removed the clutch fan for an electric fan for deep water crossing. The best bang for the buck fan (efficient moves lots of air) is the fan from the 90's Ford Taurus.
Correct, it is closely related to the Colorado/Canyon. I was under the impression they were clutch fans too. This might end up being easier than expected.

That sounds like the route to take. You can put a switch in between the power going to the relay to disable the fan, but you might want to put a lighted one in to remind you when it's in the corrrect position.
Skip the switch. You let somebody take it to the store and it comes back blown because it overheated. Put a thermoswitch on it so its all automatic like stock. If the colorado in fact is electric the wiring may already be on your truck.
As long as you understand that no electric fan can move the air of a mechanical fan. There was a reason they put a mechanical fan on there ... the electrics weren't enough. They would have used the electrics in the first place if they could.

I took the clutch fan assembly completely out of my Mercedes. I replace it with a spacer and mechanical fan. I left the electric fan in place in front of the radiator on a separate controller. I reallly dont trust clutch fans any more than I trust electric water pumps. They say the clutch type reduces power and makes more noise, but not that ive noticed.

At lower engine speeds your mechanical fan isn't capable of moving the air the a fixed high speed electric fan will. As vehicle speed increases it becomes not even relevant and your power sucking mechanical fan is a hindrance, thus the need for the clutch aspect.

I don't know about that. The high powered Corvette has electric fans. I think if the clutch fan was that great GM would have figured a way to mount one.
Now I'm torn. The one person said it worked fine until the temp was in the 90s. Our entire summers here are in the 90s to 105 range. I just can't stand the vibration from the clutch fan. Maybe I could just knock off a wheel weight? Then I wouldn't notice the engagement. j/k On the other hand the 10 hp and mpg increase are tempting. (MPG increase for range increase, I am aware the fuel savings would never offset the investment cost)
I am going to have to continue to think about this for awhile. New tires are the priority right now.
Thanks for the help.

I know its not the same but i removed the clutch and fan from my Dakota with a 3.9 and i have never had the engine get any warmer than it did previously did, the electric fan kicks on at the temp its required and cools my truck off. i have never noticed the mpg difference if there was one but it does have a tiny tiny bit more power but still not enough to justify taking it of for power reasons but it did reduce a massive amount of vibration and it doesn't sound like a bus or a dump truck during acceleration either now like it did.
I took my fan off in February and drove it all year with out the clutch and fan in place and never experienced any problems but i would recommend adding a electric fan in your case because of the higher temps in the summer.
