Clutch fan to electric
 

Silly question here. I want to put some electric fans on my swap that is a 5.3 out of a 2004 Suburban. If I just take off the clutch fan do I need to find a big nut to put on or will the pulley stay in place due to its pressed fit?

Just unscrew the fan and leave it as is.

What he said^.....but will it show you the bang for the buck? Dont get me wrong, I am running dual electrics on my gen 1 383. The clutch fan roars like hell on my 02 siverado(when it needs to), but freewheels most of the time ;) Most of the guys on the old school board, tend to lean to the good old clutch fan? You might pick up a few ponies, going elect....but on the street, its probably a moot point.Figure the cost for the setup, vs the savings? The argument is that that old mechanical fan wont let you down? I would like to step back, & hear what the gen 3 croud has to say, as I am still learning about the gen 3:chevy: crazyL

If you are going to use the PCM to control the fans make sure you have it tuned in.

Thanks everyone. I thought that was the case I just wanted to be sure so the pulley didn't fall off when I was far from home. The PCM is already programmed for fans and I think the electric setup looks cleaner than the clutch, plus I got a dual electric setup for $15 at a swapmeet. Much easier than building a shroud and I'm not at all looking for performance gains from this build.

Clutch fan with shroud all the way;) The late plastic fans are way lighter & Move a Huge amount of air when kicked in, & still pull in some air when not engaged.

Most electric fan assemblies RESTRICT air flow at high speeds.

X2, I use clutch fans whenever possible, haven't had one of them quit working yet.
