Well, I started the fan install today and removed the stock fan and clutch assembly. I proceed to drop in the electric fans and low and behold it doesn't fit. Do the 1/2 tons come with a 32" or something smaller? I only have 28 inches of core/fin area. It looks like my only other choice at this point is to install a 34" radiator. Here are a few questions.

1. Are the 34" radiators from the Sub/Tahoe/Yukon?
2. Does this larger radiator just "drop" into place where the existing radiator was and use the existing mounting locations?
3. Where do I get a new 34" radiator?

Parish8, you said you got 34" radiator? Thanks for any help.

I just got my 34" radiator from www.radiatorbarn.com .(thanks parish8 <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> ) They have excellent service and great prices for brand new radiators. Much better than any dealership I've checked. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> They even come with the little quick disconnect tool and some new fittings. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

I just ordered one for a '00 2500HD pickup truck with the 6.0L. I measured the core and it's just slightly bigger than 34".

Thanks John, I just checked there and that's where I'm going to order the radiator from. I imagine when I order I should make all the selections match my vehicle like the year and stuff except get the 6.0L radiator?

lol, after all that you still didn't get that you needed a larger radiator <img border="0" alt="[bang head]" title="" src="graemlins/gr_banghead.gif" /> , yes they prety much just drop in, the only thing i did was trim down the rubber flaps on each side of the radiator to fit a little better.

When I ordered mine I put in Sierra 2500 instead of 1500 and selected the 6.0L motor instead of the 5.3L.

Make sure you put in a 2500 model because the 1500 series pickups don't come with the big radiators unless it's the 1500HD model. Just put in 2500 to be safe. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

John, thanks for the info, I'll use it when I place my order.

PERMA-COOL MAKES ONE THAT WILL FIT THE SMALLER RADIATOR.

The Perma Cool fans are $620 for a dual 14" fan setup that fits the 28.5" core.

The new 34" radiator and flexalites cost about the same together(maybe just a little more) but, you end up with a bigger radiator and dual 15" fans. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Has anyone went the Perma Cool route? I think they just came out not too long ago.
