I haven't been able to get my 68 Dart 318ci to cool properly and after doing two drain/flush and replacing the thermostat, I'm now replacing the water pump. When I did the drain/flush I replaced first with all 50/50 Peak coolant and then again with about a 70/30 mix (mostly water) plus a container of water wetter to help with the issue. Still overheating...
First question, I need to get screw in ports for the top of the water pump and wanted to run it by here first whether I measured these correctly. The smaller one on the right measured 5/8in where the hose would connect and the one on the left measured 7/8in at the end where the hose would connect. Does anyone know which fittings I should get?
Second question, should I go ahead and replace the radiator at the same time since I'm doing the water pump to rule that out as the source of the problem? When I was troubleshooting everything it seemed as if the radiator was working...and I burped the system by waiting for the thermostat to open when it heated up enough and filling up the radiator.
