Ok guys,

With the new motor, A/C, and traffic, I watch the temps rise to a point that I feel uncomfortable with the aluminum heads. (220 and keeps climbing if I let it) I replaced the radiator a few years ago, but I just don't think that a stock unit can handle the extra cubes. So, I am looking to upgrade my current radiator with something else. I was looking at the catalogs and would like some opinions.

Be Cool, Fluidyne, Griffin, ??? Also 1 or 1.25 tubes? The one catalog says that 1 is good for up to 400hp and 1.25 are good to 600hp? Also thinking about adding a little Red Line Wetter than Wet? Is it worth it have you used it?

Discuss Please...

 

I have always had great luck with the pep boys/advance auto modine 3 core brass/copper that runs about $100-$125.

 

I don't think it's sticking. I just replace the thermostat when I rebuilt the motor. I put a 180 in it and it seems fine during normal driving. I will see it climb a little in traffic, but it doesn't get above 210. It kind of sits there until I can get moving and then it goes back down. However, if I am sitting in traffic and hit the AC, it just starts climbing. I can get about 5 to 10 minutes and then it gets around 210 and continues to rise. I let it go one day and after it hit 225, I pulled off and let the car cool down. I can swap out the thermostat, it is easy enough. I was even thinking about installing an electric fan on a switch, that I can flip on while I am sitting in traffic. However, I thought that the 347 was the cause and the radiator just isn't sufficient

 

Summit "Northern" aluminum radiator seems to be what people are liking as far as good AND cheap.
I think they are lik $170-$180

My car also runs cooler with a 60/40 ratio.

 

The afco radiators are pretty decent and really inexpensive for being an aluminum. The universal one that i'm looking at for my car is about 180. Thats a good bit cheaper then the other places I looked.

 

I have a Fluidyne....I remember it being expensive as fuck but I've never had any issues with it running too hot. I also have aluminum heads...

 

First, thanks for all the input!! I do appreciate it.
Second, I have looked at a few of them, but I did not know about the Pep Boys Modine.

The aluminum one I found from Summit was $299.
The Griffen was $160. (22x19)
Be Cool. $575 and I have not heard of anyone who bought this?
AFCO appeared to be a univeral fit. (I would perfer to get one that made for the Stang.)
Fluidyne, $349. I have a friend who said the Fluidyne is the way to go. He put one in his 95 and he said he never had problems after that. However, I thought I read where someone bought one and it leaked from the factory?? However, I am old and get confused pretty easily!!

Any ways, I am thinking that with what ever radiator I go with, I will run the mixture of 60/40 and some of the water wetter.
