22" & 26" Rad Width?

[uk-maxie]

Hi all

Can someone tell me what the 'depth' (apologies - i wrote width in thread title but cant edit it) of the top tank is on a 26" radiator please?

Our 22" rad - which I thought was the original, but I suppose it could have been swapped before we got the car 26 years ago - measures near-as-dammit 3.5" at its widest (deepest?) point.

These pics show what we have:

Doesnt show it very clearly here but the widest/deepest point of the top tank is approx 3.5"

Numbers on top of rad:

Or maybe that's not the correct rad (car was originally a 318 Sport Satellite, now has 440)?


The reason for asking is that we have tried to fit an original style viscous fan (from Mancini) but it does not fit in the gap we have between the rad & the water pump. I know there are different size clutches available, and have already found that we could pinch another 1/2" if we changed the clutch, but we need to gain more than 1/2 to provide enough clearance. Could do with reducing the o/a fan length by 1"

So I was wondering if the 22" rad is a bit wider than the 26" - which the fan/clutch assembly we bought is probably made for :icon_scratch:

Over the years we have added more core depth to the rad to maximise the cooling (3-core now?), so the core is flush with the fan-side of the top tank. Maybe this is where we have lost 1/2" clearance? :icon_scratch::icon_scratch:

Looking forward to any words of wisdom...

Thanks, Rob

While youre all pondering that query...


I've just checked our rad number here:

http://www.rosevillemoparts.com/reference_radiatorguide.php

and it looks like it's from a 1970 440/auto powered C-body :confused:

so could it be that a 22" C-bod rad is deeper than a 22" or 26" B-bod rad?

Is there anyone out there with an original, or original spec rad in a 1969 big block b-bod plymouth that could measure their top tank depth, so we know where we've lost our clearance, thanks :eusa_pray:

Your tank isnt the issue, and yes I looked up the numbers, being a 70 C body bigblock 22". I will say the 69 B 22" rads were the round top version. Brackets and how they mount would be where I would compare dim's. However, is there a chance, even a small chance youhave your motor mounts bolted to block on wrong side of ears to push engine forward in compartment!!

Thanks chignikred (hope i spelt that right! :icon_lol

I did think of the engine mounts, as the k-member was 'adapted' to fit the 440 mounts, way back in '87 when we swapped the engine. I cant remember what was done but I did wonder if it put the engine further forward than it should be.
I got a friend with a 68 GTX to check his engine position and thankfully it's the same as ours - 14" from the front of the head to the rad support.

So I guess the lack of space is down to the size & mounting position of our C-bod rad :icon_rolleyes:

Trouble is, if we find the 'correct' 69 22" b-bod rad, it wont be as efficient as ours unless we get it re-cored; which may reduce the clearance again :eusa_doh:

I just want to throw this in here, you may already know this but I didn't.

I've got a numbers matching Grand Spaulding 1969 Coronet R/T 440 6-pack and it has a 22" radiator in it. Blew me away when I first discovered it, but after research while restoring I found out that it's original.

Thanks Grumpy, that must make your car even more special! Although I suppose that means there may be other 440-6 or hemi cars with 22" rads?

Couple of questions if I may...

Does the car have the smaller aperture core support to go with the 22" rad, or does it still have the larger opening like you'd have expected?

And would you be able to measure how deep your rad's top tank is? Ours is 3.5" at its widest point, and a friend over here has a 26" in his 69 R/T Charger that is 3" measured from the core support to the rear-most point of the top tank (so his top tank is prob less than 3", allowing for the gap between it and the core support).

I presume you have a clutch fan? I've heard mention (on here I think) of a fan spacer, so I presume there was an option to have a fixed fan with a spacer but no clutch? Does anyone have any details on this fan... what it looks like and if it's available anywhere?

Thanks again :icon_salut:

It's dark, but I just went out to the car storage building. (not a problem, I'm up at 3 A.M. everyday! ) The top of the tank is 3.5" and the opening is DEFINATELY for a 22" radiator not a 26". There's a clutch fan on there but I believe that I put that on there.

I think I have a problem though and suspect that this NOT the original radiator. It looks like it's not a 4-core. I'm going to have to have it re-cored.

As far as the car goes, I think the biggest thing is that it's coded rear tail stripe delete. According to Galen it's 1 of 99 that were ordered without the rear stripe.

The round top rad measures 2 inches, where yours measures 3 1/2. I have a 22 inch rad for a big block, the narrow top tank raises the shroud location, and your fan should line up. The round top rad also places the cores to the front of the case leaving more room for the fan. I need a small block rad for my 408 six pack, but when I ordered online I got a rad the same as yours with D/S top hose and P/S lower hose.

I missed your post when you posted it long ago so just now commenting on this.

I am not sure exactly what you are referring to as numbers matching since the 440-6 was not offered in the R/T until the 1970 model year. If it came from the dealership that way new then they added the 6 pack.

If your R/T was an original no A/C auto trans car then I believe it would have come std with a 22" rad. UNLESS it was ordered with the rare A32 Super Performance Axle Package.
