Aluminum Radiator for a GN

[Mad_Trbo]

I can't see why the f-body rad wouldn't cool better than what you have even with the stock fan. You may be able to score the fan for next to nothing if you look around at the yards. Or, look at Auto Zone for a new one.

Try the rad first if that is the only thing $ will allow right now.

Agreed..

Air conditioning?

I ran the F-body radiator with the stock fan on my 10 sec. T-Type with no problems at all. My car also had a PTE FM on it.

Obviously no a/c

I run an F bod with a Cottons. Runs 165 all the time. No AC though.

F Body radiator:
-89 with 5.7 tpi
-aluminum w/ plastic end tanks radiator for a 92 Z-28. It fit without any mods and weighs half what a stocker does.
-lifetime warranty and it weighs only 10lbs unlike the 26lb stocker
-87-92 Camaro Iroc or Z
Autozone#- 433918

Kind of confused here. The top one says 89 with 5.7 TPI. 89 what? Camaro?
Then theres the aluminum one with plastic tanks. Fits with no mods. So it has oil and tranny cooler hookups like the stock one?
Is the #433918 a general number describing everything above, or are these different radiators? Its gotta be different radiators since youve got an 89 something, a 92 Z-28 and an 87-92 iroc. So is #433918 the "F-Body radiator"?

When going to the f-body rad do you just do away with the oil cooler entirely? Will this cause any problems if you still want to use the car for long trips?

Obviously no a/c

Actually it had good cold A/C. I seldom sat in bumper to bumper traffic with the A/C on because it was not a daily driver but I drove it on the power tour with the A/C on the entire trip including stop and go traffic with no problems. I have been into turbo Buicks since the early 90's and had quite a few different cars and never ran anything but the stock fan and never had any problems. I think a big part of keeping these cars cool is the high pressure high set up the factory used. Its the rubber stuff the factory installed to force the air to go thru the radiator as opposed to bypssing it. Most people remove it espcially when going front mount and it makes a big difference. I also have a 70 GS455 that uses a stock 86-87 fan with no problems.

A medium-tube high-efficiency (like the Modine X2K core) 2-row has 44 tubes per row, 88 tubes that are 1/2" for a total of 44 tube-inches. The flat-to-tube ratio is .87 for an effective 38.3 tube-ins.

A small-tube high-efficiency (like the GM HER or Modine "H" core) 3-row has 44 tubes per row, 132 tubes that are 3/8" for a total of 49.5 tube-inches. The flat-to-tube ratio is .83 for an effective 41.1 tube-ins.

A standard replacement 4-row has 29 tubes per row, 116 tubes that are 1/2" for a total of 58 tube-inches. The flat-to-tube ratio is .87 for an effective 50.5 tube-ins.

A single-row aluminum (F-body) has 39 tubes per row, 39 tubes that are 1-3/8" for a total of 53.6 tube-inches. The flat-to-tube ratio is .96 for an effective 51.5 tube-ins.

A original equipment Harrison 3-row has 40 tubes per row, 120 tubes that are 1/2" for a total of 60 tube-inches. The flat-to-tube ratio is .87 for an effective 52.2 tube-ins.

A small-tube high-efficiency 4-row has 44 tubes per row, 176 tubes that are 3/8" for a total of 66 tube-inches. The flat-to-tube ratio is .83 for an effective 54.8 tube-ins.

A large-tube high-efficiency (like the GDI/Proliance "VX" core) 3-row has 44 tubes per row, 132 tubes that are 5/8" for a total of 82.5 tube-inches. The flat-to-tube ratio is .9 for an effective 74.3 tube-ins.

A 1" double-row aluminum (like the Be-Cool, Griffin, Alumitech, Jegs, etc.) has 41 tubes per row, 82 tubes that are 1" for a total of 82 tube-inches. The flat-to-tube ratio is .94 for an effective 77.1 tube-ins.

Sorry, I just cut and pasted this from my 18 page parts list. Those years/descriptions were cut from what others posted on here, I wanted to save it for later. Basically it will be from a 87-92 Iroz or Z with a 350 TPI. Others posted no mods other than moving a base rubber over a hole, I hardly call that a mod. That AZ number is just that, an AZ number. It may be different from Oreillys, Advance, etc.

Cool!

Thanks guys!!!

I just went to Autozone and bought the rad. I'm going to put it in right now!

I'll post the new Temp tonight. the temp now is 230 on a 80 day.

Thanks again,

Brent

 

[disco stu]

Yeow that's hot.

 

[Underboost]

Ok so the Rad fits perfect.

I do have a trans cooler so thats good.

But the stock oil line will not fit the new rad? Maybe I should have noticed that before I got all trigger happy. lol

does anyone know what reducer i need?

I would assume that you already have a 160 deg. thermostat. Autozone is where I just bought mine. Also not sure on your particular chip but the stock chip, from what I read will not activate the fan untill it reaches something like 195 deg. (don't " " me on the exact number). So I hope your fan comes on way before the factory setting.... Just my thoughts, good luck and by the way 60deg. and raining here.....

Well I think I need the oil cooler do to the car being a daily driver. I'm going to take this Fbody radiator back. I have just talked with Becool and for the perfect set up with everything i need for $1,800

 

[Blaze]

Why don't you just buy an external oil cooler? Beats the hell out of spending $1800 for a radiator

I hope you're joking. Get an adapter and run the one you have. Is this a heat exchanger for a nuclear reactor, or a radiator for a buick?

 

[Squid4life]

my hot air to IC'ed conversion doesn't have an oil cooler yet. Still stays cool, keeps good oil pressure. I would rather have an external, like my tranny cooler anyhow.

Today was "stupid move" number 847. Was adding the casper heavy duty wiring and relay for my ramchargers dual fans. Couldn't get self tapper to start, so I decided to drill a hole and bolt the relays. I had a little metal backet to hold the fans in. Pushed a little harder to get bit to go through metal. It did. Then it went through the plastic fan shroud. Then it went through the radiator. I don't think I made it to the a/c condensor, since there was no hissing.
So do I have my radiator man fix it like one of the guys earlier mentioned or go with the f-body?
Correct or confirm that we shouldn't need the oil cooler.
