Well....undoubtedly I screwed up the plastic petcock on my radiator because I didn't know how it worked. It just spins and clicks. How do I get it out without messing up my radiator? I searched and couldn't find anything on how to change it. I found a thread where somebody elses messed up and they got one at NAPA, but no details on how to do it. I got it open to drain the radiator, but I can't get it to close back shut. I have an 04 2500 quad cab CTD. Any help is appreciated!

I believe you turn it 1/4 turn CCW. pull it straight out, I believe there is a "O" ring, replace it , install drain plug and turn 1/4 turn CW that should solve the issue;;;;

Thanks! I'll give that a try tomorrow.

I read somewhere that its pretty common ,but what happens is the insert inside the radiator is moved toward the inside and you need to insert a pick or something to pull it back out then carefully insert the plug.

Thanks guys. I slept the frustration off last night, and went back out today and had it out in just a minute or two. I spun it to the most loose position, and tugged on it with pliers while prying with a small flat screwdriver. It wasn't even broken, it had just spun in the seat it sets in. I cleaned it and put it back in the correct position, and added a little distilled water to test. It worked fine and didn't leak, now that I know how it works. I didn't even need to buy a new one. Thanks for the help.
