aluminum or copper radiator ???

Pulling front cowl off 37 Chevy to replace a beat up radiator. Running a 350 ci
mostly stock. Some say go 3 row aluminum, some say go copper ??? Radiator has a/c condensor on front side, with an electric fan on top of that. Runs a little on the hot side in 90" weather, but mostly pretty good.

One more question : anyone use the stainless steel fan blade replacement for the stock fan ? It's supposed to flex like an outboard stainless prop does at high rpm"s...... or is it bogus. Might as well do a few updates while the nose is off.

Brass not copper. Flex fan, they cool real well. I ran one for 4 or 5 years the only thing I didn't like was it was loud but it did work great.

I know a lot of guys get good results with either style radiator but if the aluminum one fails you will be hard pressed to get it repaired.

I personaly believe the copper is much superior but probably also more expensive.

Brass, ok. ( had a senior moment )............did the fan get loud at high rpm's or all the time.

I was worried about failure too. It's a real job to get the radiator out of this rig,
and who's gonna fix an aluminum one. I see prices all over the place for aluminum.

Aluminum is far superior to Brass as far as Cooling. All the new cars use aluminum. On average they last about 10-12 years . The plastic part (tanks) are usually the first to go. The seals start to leak in between the tank and the header.
If you don't have an issue with cooling and the size and shape of the radiator you need is odd, brass may be you better choice, as it can be repaired, re cored , and rodded if needed.
If you can get an all aluminum, with no plastic...that would be Ideal.
I bought a summit aluminum radiator for my 64...I am very pleased with the price and quality.

It is currently my opinion that nothing beats a well-built aluminum radiator with engine-driven fan, factory fan clutch and shroud. Here is one of many....
Chevrolet Radiators- GM 2003 - 1937-1939 Chevy Radiator
I would never mount a fan in front of the radiator.

this...
brass/copper also can't hold the psi that alum ones can.. and that can mean the difference in boilovers or not.

todays engines make more power running at 200* than the older style at 160/180/190 a 7 lb cap won't cut it. and neither will most copper/brass heat exchangers

I like Copper easy to repair at home if you can solder and in my opinion there isn't much or no Electrolysis to worry about; or needing the Sacrificial Anode you need to check and replace with aluminum!!!

When comparing copper radiators to aluminum radiators, remember that copper transfers heat through itself better than aluminum, so copper is better at moving the heat away from the tubes inside of the radiator. Radiators that are made of copper and brass are generally more efficient than the SAME size aluminum radiator.

Aluminum radiators are better at transferring heat out of the liquid coolant. Comparing the two types of radiators with the SAME dimensions; aluminum radiators have the advantage of being physically lighter in weight. With increased airflow an aluminum radiator can be made to be as efficient as a copper radiator. Keep in mind...you must have the airflow to make aluminum radiators work!

I use both types LOL But I do like copper brass better because its easy to repair them

nice link...
but copper/brass need more rows of tubes than alum as the soft metal bigger tubes can't take the psi. so they tend to use smaller tubes and more rows that slow the air flow through the core..
making the alum needing more airflow almost a moot point. as the tubes have more area and more fin area around them than the smaller copper/brass multi row does..
copper is tons easier to fix.. but todays alum ones don't tend to need fixing.. and with many running alum intakes/heads/etc the Electrolysis issue is there anyways..
will be book marking that link tho..

bigger issue is shops that can recore an older unit.. or fix them..
many have gone away.. it wasn't that long ago that there was at least one shop in every town around here.. now I think there is 1 within 30 miles .
