On my 98 Intrigue it's on the bottom left side of the radiator. Push in and turn it about a half turn. It's not threaded but has a catch pin. Be careful not to break it. Learned the hard way but most parts stores have a replacement. Tip: grease the o-ring on the petcock when replacing it or installing a new one. It will be easier to turn the next time.

Try the rear side of the radiator approx 1/3 down from the top

You will find that it is located on the bottom of the radiator. If you do not find a drain Petcock on the bottom of the radiator you must remove the lower radiator hose in order to drain the radiator.
