62 Fan Shroud ???

Here's another pic I found:

The '63-'66's use a completely different fan shroud. You can buy them new from the aftermarket, or if you're real lucky, you can find a good used one.

Does this look like the original 62 radiator?
The reason I ask is my 62 shroud doesn't quite work with this radiator.
It's like my radiator is about 1/2 too thick.

That appears to be an original '60-'62 radiator. I wonder if the shrouds were specific to the number of rows in the core?

[LostMy65]

I guess I'll add a spacer between that radiator and shroud.
I'll get some measurements and post them.
I'm hoping to get others to post theirs for comparison.
Either my radiator is a lot thicker than usual, or like you say; the shrouds were radiator specific.

I lined these three up for comparison.
It's hard to tell exactly, but they all look to have the same height mounting flange.
Maybe the second pic's flange is a little taller. - Don't know.

Any chance you've got a heavy-duty or 3/4-ton radiator?
I ran into that same problem when I went to the 3/4-ton 4-core radiator, and had to find the right shroud. The other two shrouds didn't fit it.

It could be I have a thicker radiator.
I took some measurements.
The shroud sitting flat is 2-1/4" from mounting flange to barrel lip.

And the Radiator is 2-3/4" thick from mounting flange to innermost surface.

That might be it.
Do the shrouds for the heavy-duty Radiator look the same other than a taller flange?

Is your radiator a 4 row core Robert?

The one I had back in the 80's was surely the barrel type.

There are actually three different shrouds available for '60-'62 trucks.
Manual-trans 1/2-ton, early version, is shown upper left.
I've found one of those in a junkyard on an untouched '60 or '61... it was rotted away, so I left it, but it's the same one shown.
What I think is a later 1/2-ton shroud ('62, maybe '61) is the one on the upper right. The barrel at the radiator is wider than the mouth at the fan, so it covers more area on the radiator.
If you have an original automatic trans truck, you also got a bigger radiator, and it had the trans cooler built into it.
The automatic shroud is a full shroud that covers the whole radiator, has a notch at the bottom corner for the trans cooler lines, and attaches to tabs brazed onto the mounting flange of the radiator. Shown on bottom.
The other two don't cover the whole face of the radiator, and they mount using the six bolts that hold the radiator to the core support.
The auto-trans radiator and the 3/4-ton and up radiator are wider and a little taller, but are a direct bolt-in to a 1/2-ton '60-'62 truck. The core support, at least on my '61 Suburban, has the blind nuts in place for both radiators. They made-up the difference in the width of the core by making the mounting flanges narrower, thus keeping the mounting bolts in the same location, but put one farther down the core support.
Over a couple years, I scored all three of these shrouds... I put a 3/4-ton 4-row radiator in my '61 Suburban, and kept the full auto-trans shroud for it.
I got a repro heavy-duty 7-blade clutch fan from YearOne--the application was big-block Mopar with A/C. The Chevy and Mopar fans interchange... I got the largest diameter one, which filled the opening in the shroud the best. It was a toss-up between BBC with A/C and BBM with A/C... the Mopar was a little larger in diameter.
Spend the money for an authorized reproduction fan! The generic aftermarket fan had a warning sticker on it that said not to exceed 4,000rpm.
It's been a few years, and I never got around to making the mounting tabs for the shroud. The HD fan and 4-row radiator has kept my truck cool in Atlanta traffic in the summer. The fan, even set so far back, pulls enough air at idle to suck a piece of paper tight to the radiator from the front. It moves a LOT of air.
I expect it to pull birds out of the sky once I finally get the shroud on.
I just found another auto-trans full shroud and snapped it up. Shoot me a PM if anyone is interested.

I realized I never posted back.
I ended putting in about a 3/8" spacer.
