Electric fans - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am planning on running 2 14" Perma Cool electric fans on my new motor. A guy at work told me not to use the nylon fastners to attach them to the radiator, b/c it could rub a hole in the copper tubing. Has anyone else ever heard of this?

Never heard of that...............thought they bolted up to the existing shroud bolts.................

I have my fans laying right on the radiator, but not mounted with the nylon zip straps. I don't like the idea of sticking the things through my radiator. I doubt they would cause harm or else they would come out with something better by now, right? But I still wouldn't use them either. Make some mounting straps out of some flat metal and fasten it to the top and bottom of the radiator. If they do indeed lay against the radiator, like they should, you don't want them sliding around, or this will eventually rub a hole.

I won't use ties either.

Nah, nylon isn't abrasive. THe most it'll do is rub off the paint, and maybe put a nice shine on the copper. To each their own..

True but metal will be stronger for sure.

gldevall · 03-26-2003, 09:41 AM

Should they be mounted even or staggered like the pics g provided?

Dave mounted his side by side I believe, he ought to be on later and can post some pictures. Basically whatever you prefer.

Here's an old pic of how mine are mounted. But my fans are not Perma Cools. My fans are Spals. It doesn't really matter where they are location wise. Gerardo mounted his the way he did because they were to big to have side by side.

Mine looks identical to Mike's!

Dave what did you use to mount yours with? I'm going to use the same fan setup you got.
