Hey all, I'm trying to drain the coolant and am stuck.. I found this thread:

I can only get the petcock to turn about 20 degrees, and no coolant comes out. When I try and turn it more, the ratchet extension starts to mangle the plastic, but the thing doesn't turn any more. So, how many degrees should it go before it releases coolant, and/or what could be causing it to stick? Thanks.
Never mind, figured it out!
You turn it to unlock it, then pull it out.
