Caravan/Voyager Radiator Draincock

.. the new one first, the following will make more sense since you can see better what I describe.

You are right, it is twist and then pull, only you have to twist the right amount, no more and no less, and then pull. Having a new one to compare will give you a better idea of how much to twist.

Also, when pulling, be careful as the neck where the part install may crack if you pull too much or at an angle. A little oil or grease will help install the new one without too much force, and also prevent the o-ring from being cut during installation. The new one will first be pushed in, and then part twisted to seat fully. Do NOT overtwist or you will have a new leak and spend 5 more bucks.

I have a 2000 Dodge Caravan. The draincock was very difficult to open but opens in the counter clockwise direction. (closed is horizontal). I used a small crescent wrench. After I changed the antifreeze, the draincock leaked. Thanks to this forum I figured out I was not alone. I took the advice given here of buying a draincock (about $6) and this helped me understand how to get the old one out. It is not 1/4 turn and pull, but instead just shy of 1/2 turn and then wiggle. It will come out. I would say it is about 160 degrees out of 180 degrees, with 180 degrees being a 1/2 turn. If you turn it more than 1/2 turn, it will damage the draincock. The o-ring in mine was broken. After removing the draincock, I pulled out a few pieces of broken o-ring out of the housing, lightly lubricated the new draincock with silicone lubricant, and it went back in just fine with some wiggling. I agree with shade tree mechanic, just pulling the bottom hose is much less hassle.
