I assume you were having overheating problems with your old radiator? If so, it would be interesting to see the improvement by running the same coolant you had in the old radiator. I'm in the south and run 50/50 antifreeze/distilled water. Please report back with your opinion of the new radiator.

Yes I installed a fan in back of the radiator that was pushing 2700CFM and it still got hot so that is why I ordered and installing the Aluminum Radiator was getting tired of driving and looking at the temperature Gage.

Why buy the water when you can buy Prestone 50/50 which is anti freeze and water?

A brass radiator will run much cooler than an aluminum one; why do you think Henry used brass instead of aluminum, which is much cheaper than brass?

gfstew, I'm not a fan of aluminum radiators, so I have no advice on coolant requirements on them, but I do have a pointer for you on your fan: You will notice that for all the cars over all the years of manufacture, they all have fans that pull air through the radiator, the best of those having a shroud. Pusher fans are not nearly as efficient and are never used in new cars for that reason. Also, please discount any confrontational replies you get, there are few of those kind on our Forum.

You will need to have some anti-freeze in the radiator to prevent corrosion. Having an aluminum radiator makes having corrosion inhibitors more important. Check with the radiator manufacturer for their recommendations.

This may be a dumb question. When you installed the electric fan on the back of your radiator, did you have it wired up to push or pull air through the radiator? If you are going to use an electric fan, it is best to use it as a "puller" on the side of the radiator that faces the engine. Placing the fan toward the top of the radiator (where the coolant is hottest) will help as will the use of a shroud around the fan.

hi if your car is in a garage, and it does not freeze, I would use distilled water, I use the water that I get from a dehumidifier its FREE, and a water pump lube,for no rust, or water wetter, and this way if it does overheat, it does not make a MESS, stain the paint, and more,,,!!! for at least till you get the problem solved, I also found out that PEAK ANTIFREEZE, does not to foam out as much as other brands I have one car that is not in a heated garage, and I use PEAK not deluded ,50-50 way pay for water,? mix it your self, good luck with new radiator, let us know how you make out , with the over heating problem my 2 cents 1937 RAGTOPMAN

Carcrazy brings up an excellent question. A "pusher" fan does just that, it pushes the air thru the radiator and is mounted in front of the radiator. If in fact you are using a "pusher" fan, mounted behind the radiator, you will fight the air trying to come thru the radiator at speed. I'm also not a fan of aluminum radiators, but as to the aluminum vs brass/copper, there have been several articles in various hot rod related magazines and the brass/copper seems to run slightly cooler.
