I'm pretty sure I ham fisted the plastic drain petcock on the radiator in my 04 2500 CTD. I had to replace the water pump, and had no idea that you pull out on it and do a 1/4 twist. I just turned it until coolant ran out. Hopefully, one of y'all can tell me how to get it out without destroying the radiator. Some Russian dude on youtube showed one that he got out, and the part number of the one he got from NAPA...but offered no advice other than he beat the #@!&? out of it to get it out. Any help is appreciated!
