I couldn't tell you where I've begun and where I stopped. All I know is that it no-longer over heats w/ the bumper off. I thought it was an air leakage somewheres but couldn't establish an answer for it. I did a pressure test on the radiator and the needle didn't drop a hair within 3 minutes. Im going to check on that insert now. Was it easy to replace?
