This is the radiator and electric fan set up I bought.
I guess I will put the radiator in with my shroud and Perma Cool flex fan until I get it figured out how to mount it without the shroud.
If I could get some more pics on how you guys have mounted your fans it would be much appreciated.

Like I mentioned, to mount the radiator without the shroud, the best solution I've found is the upper core support plates that are used on Camaros, Chevelles, Novas etc..... They come in different widths.

That's how I did dad's GTO back when he was experimenting with electric fans. His radiator is also encased in the factory shroud and used to hold the radiator by bolting to the upper core support. With that gone, it was just as simple as bolting a Chevelle upper radiator support to his existing core support holes and it holds the top of the radiator as designed, and looks stock. Very easy to do. I didn't have to drill anything. In fact when he decided to go back to his clutch fan and stock shroud, it was as simple as removing that top Chevelle plate, sticking the radiator back into the factory shroud and bolting it down. Literally a 10 minute process.

Is this the core support you are talking about ?
The radiator is going on with stock shroud at first. I can't put any electric fan until I figure out how to hold the radiator.
The radiator I have looks to be made by the same people who make Cold Case. Looks well made.
Its 70 deg on a warm day where I live and it won't be street driven. If I can find a way to set the electric fan shroud I do have back 1/2"-3"4" it should help.
I will try that before getting the Flex A Light 460$ fans.
I might not have much of a problem since I live where its cool and I drag race it.

Yes I used one of those.

Hopefully this will work out for you - you can see the flat area of the shroud blocks much of the core and thus air flow

Yup, I had a very lengthy thread on this very thing a few years back. Cold Case makes them the same way. Amazes me that radiator companies still sell this stuff.

I can tell you ahead of time to save you the trouble, cutting openings in that aluminum shroud and attaching rubber flaps to try and allow more air to pass through did absolutely nothing.

The really bad part about that design is just having that aluminum shroud flat and up against the radiator core like that. It pretty much just stops all air flow and what little that does get through really isn't enough to control temps properly. Basically what happened when I was trying to make that work was that temps would eventually creep and get to around 190 and stay there, and even with both fans running and going down the highway, the fans wouldn't shut off, I could never get it back down to a shut off temp and I wasn't willing to raise temps on the controller any higher, especially 190 for a shut off temp, LOL

Once those electric fans and shroud came off, stock shroud and clutch fan went on, I couldn't get the engine over 175 degrees no matter what I did with it and most times it would run in the 160's with no other changes (still same Cold Case radiator etc...). That was a real eye opener to me on how air flow efficiency through the radiator mattered.

Cold Case in my Firebird has been excellent.
AC pulleys to overdrive water pump and fan.
Should is key player here. Still have original on mine.
Standard fan clutch with 7 blade AC fan from 76 TA.
I have to be on highway to hit 170!!
Most of the time it’s 165-168, even when it 90+
NOS AC Delco thermostat 170.(cracks open at 165ish)
Had a cheaper two aluminum eBay unit before and
It did not cool as good as cold case.
That’s why I did every mod possible because I thought,
The old two row aluminum rad was not the issue.
It was two rows of one inch tubes.

Sadly it was and when it began leaking I replaced
With the CC.
Stop at a store it heat soaks up to 185-190. And drops
Back like a rocket to 170 before I leave the parking lot.

Agree, I have no issue at all with Cold Case radiators. Good quality, fair pricing, and they work. I'm using them in 4 cars and they work, fit and function just as well as the expensive Griffins I run in the other cars.

It's the electric fan setup that stifles the radiators cooling ability, and there are dozens of other radiator vendors that sell those electric fan setups designed the same way.
