Radiator Help Needed!

Hey Guys,

I have a '91 with an S-trim (standard install,nothing special) that needs a new radiator. This car used to have a brass 3 row radiator and the factory clutch fan.

I just bought an American Eagle 2 row radiator and it's too thick because the S-trim's tensioner gets in the way when trying to hang the factory fan shroud. I even tried mocking up a contour dual fan kit I have (fans hits the blower belt).

Some notes: My old brass radiator's thickness measured exactly at 2".

This American Eagle unit measures out to 2"3/8' but their website says its 2.1" thick...anyways, its still an issue.

Radiator Dimensions:
Total: 19.25" tall (with cap) x 29.25" wide
Core: 16.75" tall x 24.5" wide x 2.13" thick
Inlet: 1.25" passenger side
Outlet: 1.5" driver side
Tanks: 2.75" thick
Tubes: 1" thick

Yes, the factory fan was notched at the bottom where it meets the crank pulley with the old radiator and perhaps I need to complete that notch all the way around?

What should I do? Move the wiring harnesses behind the rad support in order to pull the radiator closer to the support frame (sounds like a PITA)? Buy a thinner radiator? The Champion 2-row measures out to 1.75" thick, while the 3 row is apparently thicker than my American Eagle unit.

A few things at my disposal are:

Griffin Dominator Rad (was too big).
Modine 3 row brass replacement radiator that is in my SVO currently (I can always play the old swaparoo here)
The old leaky 3 row brass radiator that has been in this car from the 1990's.
Mark VIII and Contour fans.

To get the car going I wanted to retain the factory fan and shroud but at this point I might also entertain the idea of switching over to an electric fan. Can the Contour fan be notched? It seems too thin already.

Any help would be appreciated! Thanks in Advance.

Radiator Help Needed!

I had to replace mine in my 95 that has a v3 and I used a parts house oem type and it fit. I'd like to have a larger one but I don't think it'd work since the stock one barely clears the pulley.

Just a thought, but if you still have the old radiator why not have it redone at a decent radiator shop? You already know it fits.

It's really old and I already have had it rodded out once, but I guess I could have them re-core it. Though not really worth it when aluminum radiators are so cheap these days.

You can trim the fan shroud to make it sit closer. I have seen the dual fan units as well offset lower and to one side a bit to avoid the blower. Just some options.

I trimmed a Mark VIII fan for a friend's bronco to make it fit.

The oem shroud was notched years ago to clear the crank pulley. I think I need to continue this notch all the way around. Will this negatively affect the cooling benefits brought on by the shroud itself?

I am at a cross roads where I can modify the stock shroud (e fans wont fit w/ this rad) and keep this thicker radiator of mine OR try to get Champion to exchange it for a 2 row model where the stock and any future electric fan will work w/o any clearance issues.

If you were to move the wiring harnesses out of the way,it might give you what,about a 1/2-3/4" more clearance behind the upper part of the radiator,but will the bottom of the radiator still be too close to the pulley??

I know most guys dont like running one,but have you entertained the idea of a flexfan?? Several spacers(varying in size)are available that might put the fan where its needed.You could take some measurements,from the water pump pulley outward,to see if one of them will make it feasible.
I ran one when I had a Kenne Bell on my LX,but I cant remember what size radiator was installed at the time,as far as thickness goes.
Ive been running the same one on my 331 for 6 years now (up to 7000rpm) with zero issues.
Im not sure how it compares(cooling wise)to an electric fan,considering my LX never had one,but it cools much better than the clutch fan setup(stays between 180-210 ac on,in traffic,180 tstat) its lighter & its inexpensive.
Be careful when youre installing or working close to it though,because it will cut a helluva slash in your *** if youre not paying attention. lol.
Just thought I'd mention it as an option(maybe)

BTW- it sounds like youve got enough of them (rad) lying around to start your own radiator shop.lol

Well when I pull the radiator closer to the core support, I am still limited by how the stock saddle mounts screws into the core support, meaning if there weren't any wires running behind the rad, I still couldn't get a major improvement in clearance, if any. Am I missing something here?

Yes, too many radiators! I have to eventually sell the Griffin.
