Spring surprise - Looks like a leak in my 72 Cutlass supreme radiator. Whats the way to go with a replacement? Aluminum 4 row?
I have 455 no a/c, no shroud. Would going to 3 to 4 row cause any direct fit problems? Does Summit make a good radiator?
Thanks

Whats wrong with fixing what you have ? It can be repaired and pressure tested. It will fit back exactly.

Look for a good radiator shop in your area and get it recored. If the tanks are shot they should be able to source the correct rad for you. Do a good flush of the system before reinstallation no matter which way you go. Good time for belts hoses T-stat etc...

Zacc, their are many choices if your looking for a decent aluminium rad. I purchased and stand behind the Be-Cool, 2 row with 1" tubes made in the U.S.A aluminium rad. A little more money than others, however, keeping the car cool for many years was worth the extra cost for me.
As others mentioned, If you can find a local rad shop that still does repairs and re-cores, a 3 row copper core will cool your car well enough, no need for a 4 row unless you are towing a trailer or boat IMO.
Lots of options depending on price.
X2 on a good flush before removal, New, T-stat, hoses, rad cap and belts are always a good idea at this point.

I personally like cooling overkill, especially on a 403 or 455. I am planning on this one.

Coldcase is a new entry in the Abody world. Good reviews so far.

DeWitt's makes a very nice piece as well. Two row aluminum, 1" tubes, looks pretty stock.
