Many start leaking or people can't get them to drain and over-turn them and end up having to replace them. They also are in a very difficult spot to reach (as on most cars these days). My understanding is they turn CCW a little over 90° and pull out just a little to start draining. I couldn't get mine to start draining, and learned later on the 300M Club forums that they have to come out a little after being turned. Also the o-rings go bad on them. I ended up just flushing thru the radiator hoses. Will probably do the same thing again next time to avoid damaging it or the o-ring start leaking. Very poor design.

Radiator Drain on 99 Concorde?
thanks, Guys. I will look for it in that location the next opportunity I have. That turn and pull type petcock is vintage chrysler. I would have thought they would have gone to something better and more reliable by now, but I guess not.

I do what Bill does and carefully pull the lower radiator hose to flush on
all my Chryslers. Bob "maxpower" > wrote in message . .. > > "DLH1" > wrote in message > news >> >> thanks, Guys.

I've not done it - but that appears to be the consensus on the 300M Club forums. Perhaps if you're into the timing belt. etc., that would be a convenient time (along with the accessory belt tensioners, etc.).

Off hand I cant remember which ones have to have the radiator loose until I look at em. Glenn |
