Any Hotairs w/ a coldcase radiator????

I hear you Chatmanboy. I'm wondering if I can use the engine oil section of my Cold-Case radiator as it will "line up" with hard transmission lines. This means I would need to find an fitting/combo that would end up being 5/16" inverted flare female to 1/2" inverted flared male.

Anyone on this board recommed against using the engine oil cooling section of the radiator (not currently in use) for the transmission oil cooler hard lines?

I never bothered with the oil cooler. I ran an F-Body rad with a separate trans cooler.

No kidding. I'm attaching a "Brass Products" catalog page image which helped me get started.

I just finished up my coldcase radiator install and have some pictures and info for you. The end goal is to utilize the engine oil cooling section of the radiator, so that the factory trans cooling lines-line up to the rear 1/2" (3/4-18 thread) radiator ports. I have 1/2" (3/4-18) inverted flare brass plugs that I plan on getting tapped for 1/8" NPT. I would then use an 1/8" MNPT to 5/16" (1/2-20) inverted flare brass adapter. Will look factory but might require a bit more transmission fluid (top off).

My current setup consists of custom hardlines built to reach the transmission oil cooling section of the front radiator. I used the Harbor Freight flaring kit and hardlines (with 1 end already fitted with 5/16" (1/2-20) inverted flare male connector) and additonal brass fittings and adapters from Napa. I used an 1/8" MNPT to 90º 5/16" (1/2-20) inverted flare female (picture attached) on the front radiator ports (use thread sealant). Connected my custom hard lines from the front radiator port adapters and used a 5/16" (1/2-20) inverted flare brass coupler to join to the factory hard lines (picture attached). This configurartion works great and just might stay this way to be honest.

Here's the final result (1/2" (3/4-18) inverted flare brass plugs drilled and tapped for 1/8" NPT)

Great idea! I was in the process of starting to figure out how to do that! I too have a Cold Case radiator. On mine as delivered, the fan wire diagram had the fans BLOWING air foward thru the radiator! A call to them resulted in being insulted by the representative! He told me basically that I was stupid and that's not how it worked. So I swapped the wires to have the fans suck thru the radiator(opposite of the wiring diagram)
but that had the blades sucking off of the back side. According to my air velocity meter the air flowed at a "whopping"( I'm being sarcastic, but accurate) 8.3 MPH!
So I decided to turn the fans around on the shafts. Didn't work, they hit the shrouds. So I made spacers to just barely allow the blades to work. That netted airflow of 17.9 MPH, a notable but pathetic number. Next I detailed the casting flash off of the blades, hubs, inside of the outer ring and finger guards, and that got the flow up to around 19 MPH. Still not enough for me. Next I decided that the finger guards are very close together, and mechanical fans don't have finger guards anyway, so I removed 2 out of every 3 guard rings, and left all of the radial supports. Viola!
23.8 MPH on one fan and 24 on the other! On top of that, the fans are much quieter!
A quick follow up call to cold case resulted in the rep (don't think it was the same guy) Also insulting my intelligence by telling me their engineers were smarter than I, and they had never seen any of the issues that I related!
I did ask them if there were any cases reported where a 3 year old was running next to a driving car with the hood up and stuck their fingers in the fan.
I now realize that I and my airflow meter are stupid, but my fans run for less time and are quieter. Just sayin'..
