Radiator problem

[oldwagon]

Don't know if anybody has ever run into this problem or not. I just installed a new radiator in my 83 doolly and wound up with a leaking drain cock. Not at the threads, as u mite think, but thru the spigot where it normally drains. Tho't it mite be because I put a hose on the end of it, so I replace that drain with another new one. It leaked also. Thru the spigot. Any ideas? Mechanic said that possibly the fitting that the drain screws into wasn't installed rite. Sound feasible? I'm stumped!

I personally think drain petcocks are crap, but that's just me. I prefer ball valves if at all feasible. Does it leak all the time or just when it's pressurized? Did you pull it out and clean the back side where it seats? If it's got solder or shavings in it it'll never seal right. Could it be looking at the joint around the bung or at the threads and running down to drip at the drain hole? Hard to figure out from here, just things to think about. Hope that helps.

I have had the same problems with them some leak some don't. some will open and close and some will just turn forever. The most important thing i've found is like most things don't over tighten it or it will leak for sure and put some thread tape on when you install it. Oh and pray it don't leak.

Both leaked even with no pressure. Didn't think to clean either drain at the time. I think I will look at a ball valve if I can put one in. It's pretty close to the steering box but I'll hope for the best. Thanks.
