Default Re: Foaming/cavitating coolant in my 34

I have been fighting over heating on my 53 Victoria, my problem was putting ac in her, first thing see if there oil is the water if not its not an engine leak, if it has oil you got a problem. Bubbling is not necessary an engine leak or compression leak. i been the whole route, changed water pumps, rebuilt radiator with 4 tube core, used evaporust it turned black like it should, drained put in wetter water with water pump lube, put on electric fan and shroud, worked great in town, but on highway got hot, took off electric fan and reinstalled 4 blade fan, highway great, in town got hot, finally put on 6 blade mechanical fan everything is good, 95 deg day it gets up to 180 on highway with 210 in stop and go traffic. I will be putting antifreeze in on the back of the antifreeze container it says 50/50 dilution it wont boil until 260 deg. I use an overflow tank with a 7 lb radiator cap. even at 210 I have no loss of water or water in return tank.
