This year has been the cooling system issues year.

I am now running a replacement radiator which is believed to be an older Re-cored radiator. I have a leakless pump I installed this spring. I flushed the block during the radiator change.

Changed radiator because other was overheating. Could hear water gurgling and possibly boiling after shut down, etc and it was an old repro radiator.

I slowly have gotten this car running and I drive it in short rides around the neighborhood when I run it.

Since swapping the radiator I will pull it in to the garage, shut off the gas valve, and let it mostly run the gas out of the carb. When it starts to speed up - running lean- then stutter a bit I shut off the ignition. After I shut it off and everything comes to a halt I’ll start getting some water out of the overflow.

First time it was a couple drops/ small amount. Last time I took it on a longer trip - longest it’s been on but still only like a mile or two. I got maybe a cup or so of water out.

I’m running water with water wetter. After the first time I looked and the water was just barely over the baffle in the radiator. I know A’s will sort of seek their own level in the radiator. I haven’t checked where the water is now but after that last bit I’d guess it’s just below the baffle or even with it.

Almost seems like when I shut it off there’s a rush of water up the radiator, it hits the cap and then comes out the overflow.

System still runs hot but seems much better than it was. I don’t get the bubbling and gurgling sounds I did with the old radiator.

Do I let it go and see if it continues? Normal? Any possible causes I should look at?

System took about 2.5-2.75 gallons of water. No water in oil that I can see. There was an external crack in the water jacket that I re-repaired with JB Weld that has been there for decades.
