My 67 GTO runs at 182° max! With a 180° thermostat.

And I do not have an aluminum radiator.

Fantastic...guess you don't need one!

I have never had a factory radiator do that, even recored.

Wouldn't want to make a little wager on that would you?

You didn't either!

It's time to stop spreading untruths and spending other peoples money here.
A properly setup Pontiac will run as cool as any other make, BUT you must do your homework properly to find and fix the problem.

I'm with Charles 100% on that. If you don't do your homework and don't find out what's causing your overheating, then buy an aluminum radiator, you're just wasting money you could be spending on something you need more for your restoration. And buy telling these untruths you're putting money in someone else's pocket, and you don't even get to benefit from it. LOL

There's only two things about an aluminum radiator that lures you in. It saves weight, and has larger tubes in it. And I might add, far less tubes than a stock radiator... 3 or 4 core. Yeah it might move more water, but that's not always a good thing. Aluminum doesn't transfer heat like copper and brass do. It's kinda like the days of aluminum wiring... it caused more problems in the long run.

My radiator guy proved that to a guy from Maryland that was having overheating issues with his street/strip car... with an aluminum radiator. He recored his stock radiator it with the same core I have now. The guy said he was crazy, it wouldn't cool better than the aluminum would. So Dick said if it doesn't cool better than your aluminum radiator, it's free. They did the recore and the guy went home and put the recored stock radiator back in his car. Next day he came in and paid the money he owed. Said his car never ran so cool in all the time he owned it. So much for aluminum. True story right from 'The Man' himself... I did not make it up.

Gary, I rarely disagree with you on most issues...and I'm not doubting your story...
keep up the good work...

I see Charles knows everyone's combo, driving conditions, and feels his thoughts should be everyone elses..
Tell me Charles, what is my primary use of my car, my set up, and how I drive? Then tell me how that stock rad should be just fine with some "homework"...

Cut to the crux of the matter.

1) These cars were not built with aluminum radiators.
2) They DID NOT overheat when new.
3) Copper does conduct heat better than aluminum.
4) Aluminum twice the price of copper radiators.
5) People claim 30° cooling improvement after they spent money to compensate for a problem different than the radiator.
6) They WILL NOT overheat now, even with the crappy gas available.
7) You must make sure you have the proper pump, clearance and flow for adequate cooling, just like any other automobile. Our Pontiac's are just a wee bit different in engineering design on the pumps.

Trust me here, I tell the honest truth, if it were not for George Kujanski making me think and get my head out of my arse, I would be chasing the elusive solution still! Fifteen years with a defective pump and countless nights and dollars trying to come to a logical conclusion, only to find out that an impeller in a large cavity will NOT function as it should. And all I had to do was LOOK at it GOOD. That is homework!

All of the above reasons and a few more I'm sure I did not mention, do not justify telling people that changing to an aluminum radiator is a panacea that will fix all of your problems. It just ain't so!

Respectfully folks, let's stop telling "old wives tales".

Again, that being said,

Question: Why on earth would I be able to say that numerous others have NOT needed to have an aluminum radiator to make a Pontiac V8 run cool.

Answer: Because it is true!

Tell me Charles, what is my primary use of my car, my set up, and how I drive? Then tell me how that stock rad should be just fine with some "homework"...

I did not try to tell you that, but did you inquire about those same things before making a blanket statement?

I apologize to 3 duece 64 and the moderators for hijacking your thread.

2) They DID NOT overheat when new. Yes, they did... I was there...
3) Copper does conduct heat better than aluminum. Aluminum has larger volume..and better design...
4) Aluminum twice the price of copper radiators. So? They are better...some of us don't mind spending $ for a superior product..
5) People claim 30° cooling improvement after they spent money to compensate for a problem different than the radiator. They work, get over it!
6) They WILL NOT overheat now, even with the crappy gas available.
7) You must make sure you have the proper pump, clearance and flow for adequate cooling, just like any other automobile. Our Pontiac's are just a wee bit different in engineering design on the pumps. Then what? Call you?

Only 15 years?

I guess I'd be frustrated too...
