    Ever try to drain the radiator from the t-handled petcock into a container only to have the stream go wonky?
    Heres what I came up with to get the antifreeze into the container instead of the shop floor.
    I cut an old Lucas oil bottle and hung it on the petcock.
    It ain't dumb if it works right?

          I always use a piece of vacuum hose or something that fits the end of the petcock and drain it into a jug or pail.
          Always worked for me.......

              Great idea, this is the best I've come up with. Works!

                Mopar Vince, great idea.

                Now, can someone tell me how to drain the newer radiators with those stupid plastic petcocks? I have NEVER had one of them work. I always get mad and pull the bottom hose off and dump everything at once.

                I've always had to grab them with a set of pliers to get them off, then if you're lucky it might drain.

                I have used pliers too, but never have been lucky enough for one to drain. 99 durango, 03 ram both the same.

                I've had luck with mine, but I've worked on a few with that same issue.

                I did make the shroud 2 piece the first time I changed the water pump on the durango. I was glad I did the next time I had to change it.

                  They fixed that in '01 or so, my '02 had a two piece shroud.

                    90 degree spark plug boot fits the petcock perfectly. Shoots right into the bucket.

                        I remember reading about some of the Chev/ GM stuff built in the late 70-80's. Not only did they not put block drain plugs in some engines, they didn't put rad drain cocks in 'em, either. Only way to drain them was pull the lower hose or siphon out of the side tank, and then knock out a frost plug on each side. I vaguely remember you could buy special freeze plugs with a drain boss in them.
