Lets talk radiators.

[Charger4404spd]

Some of you know I am building a 505 stroker and plan on a 8-71 blower. Im concerned about keeping her cool and would like some input on aluminum radiators. I have heard a 2 core with 1" tudes cools better than a 3 or 4 core with smaller tubes.

I dont want to spent $5-8oo on one if I dont have to. I have looked at the ones on ebay that are priced right, but I dont know anyone that has tried them. What have you guys had luck with?

that's what I put in all of my Chargers...holds more water by volume...my opinion

[Ghoste]

Surface to volume ratio?

CUDAKEN had a blower in his he can offer lots of advice...he kept it very cool.

Any specific models you would recommend?

Fascinating.  How does this radiator perform against other radiators you've used in the past?  That's a GREAT price for what they're offering, and their mini-factoid on 3 and 4 core 'rads was quite an eye-opener.

Question: does it have provisions for mounting the stock fan shroud?  Is this designed to fit directly into the factory 'rad mounting locations?

I run the BeeCool aluminum rad in mine with dual electric fans.
Very expensive but Guarenteed to support 700hp...
They make many different models , I opted for the big bad one knowing my future plans for the car
So far it has worked flawlessly

Just a heads up thou... The fan relays are 40 amps each and there are 2. You better have an upgraded alt. if you wanna run elec fans

I should also say mine has an internal tranny cooler as well. I also plumbed a second tranny cooler in line

[Ghoste]

So is there a balance point between having a large volume of coolant and sufficient area to transfer the heat to the surrounding air?  You need fins too right or else we could just run with a giant tank of coolant any old place?

Taken at new hamburg in 2013, this motor is using a BeeCool rad



And here is mine..

[War wagon]

My father is running a Wizard rad on his 496 in his Belvedere. It's been in there for about 7yrs, works ok.... But doesn't like to idle long or temps will rise. It uses 2 x 1 1/4" cores
If it won't cool the new 572 he will switch to a BeeCool rad as well.

[Charger4404spd]

So far looks like I may have to spend the big bucks because I do want it to stay cool idling in traffic. Id anyone running one of the ebay rads in a high horsepower car?

[myk]

What's wrong with the 'rad that 383Wing linked to?  It's only $300.  If they're good enough for him I'd give that 'rad a shot, especially if it means avoiding those mega-buck 'rads...

So this radiator has a built-in 'trans oil cooler; does that mean that I don't need the factory cooler mounted in the front of the car? 

[Ghoste]

Most of the factory rads have a built in cooler and if you run everything in a factory configuration that should be enough.  If you start to abuse the trans or put in a higher stall converter, you should run both.
Myk, are you sure you don't have a cooler in your rad or that the auxilliary one is a factory one?

Didn't all of the Chargers come with a 'trans cooler mounted in the front of the car?

[Ghoste]

Nope.  Hemi's and that might be about it.  I'll check the books, maybe air conditioned cars and trailer towing packages but most did not.  What about your rad, is there a cooler in it Myk?

...............I just assumed there wasn't one in the 'rad because of the external one.  Wow-all these years I thought the 'trans cooler was standard equipment.  My car did have air?

Ok thinking about how my car is set up there are lines that go to the bottom of the 'rad (trans cooler), and then there's also the external unit in the front of the car.  This isn't right, is it?

-Just came from outside.  Ok-there is a line from the 'trans that runs into the external cooler.  Then, there's a line that goes out of the external cooler into the bottom of my 'rad.  Then, another line goes from the bottom of the 'rad back to the 'trans.  Weird, right?

[A383Wing]

nope...all automatic cars had trans cooler in bottom of radiator...the external one has been added

[myk]

Alright, so does the 'trans cooler in the 'rad have to run in conjunction with the external cooler, or is it supposed to be one or the other?  Which one is better?  Also, I take it that the manual cars had external coolers?

[A383Wing]

no coolers on manual trans cars...

those who put extra coolers on either tie them in with the original one in the radiator, or just use the external one all alone. I put a stand alone unit in front of the radiator in the Daytona....I completely by-passed the cooler in the lower part of the radiator. Some say run both, some say not....and I ferget which way to run lines if you run both.

I run just the external so I'm not heating up the radiator with hot ATF to keep the coolant from getting warmed up by trans fluid

What the Wingster said.  Hey, 383 Wing, how do you like the rad that you linked to?  I've got a two row aluminum one made by Northern.  It will still warm up on a hot day in traffic and has no drain cock. I'm thinking of replacing it.

[bill440rt]

I have a Griffin aluminum radiator in my '69. VERY happy with it.
Mounts right in the stock location, you can even mount a stock fan shroud to it if you wanted to. Trans cooler bungs are in the stock location as well, although I also run an external trans cooler also. Basically, a "stock" configured radiator made entirely of aluminum. Even in 105* summer heat with the A/C cranking the car stayed cool.

I'm very pleased with mine...actually have the rad in all 3 of our Chargers.....these hold a lot of water. Has provisions to mount factory shroud as well. Both my 66's are manual trans cars, cooler not needed. And I'm not using the cooler in the Daytona either. This rad really cured my overheating issues.

Thanks!  I might just get one coming.  Can't go too wrong at that price...
