Title: Radiator for vintage air? Stock or aluminum?
Post by: dalekerr on May 31, 2018, 01:35:57 AM
I am ordering Vintage Air for my new toy, 67 with 327 upgraded a little. The car is currently running a bit hot now, I know the stock radiator needs cleaned out. Will the stock 21 inch radiator be able to handle the new AC unit? Or should I change it to a 3 core alluminum.
The car  is not 100% original the last owner added rack and pinion steering along with a new modern distrubuter.

I plan to drive the car about 3,000 miles per year.

A little searching and you could make an educated decision.  Factory required at least a 3 row radiator when A/C was added.  If your stock radiator is 2 row then go ahead and upgrade to aluminum 3 row since originality isn't a concern.  If you are running a stock fan & clutch and are still concerned with overheating then add an electric fan.  But 190-195F is normal operating range.  Hell newer cars with aluminum engines run even hotter but that is also partially due to emissions and the ability of its sensor monitoring system.

Thanks, so a 190 thermostat and three core radiator and I should be fine?

My radiator guy says aluminum radiators are junk, tubes are too big. I would use a three row brass and copper to keep him happy.

Age old debate.  They both have their pros and cons.

Aluminum is not repairable, fwiw.

Well vintage air is installed and blowing cold. A blessing here in Louisiana, with the temps in the 90s now. Car runs cool while driving down the road with aluminum 4 core radiator and stock fan and shroud (190). Gets up to about 220 while setting a while, I may need to put on an electric fan.

Thanks for all the help from members of this site!
