Hi first time poster, and i did a quick search for this problem.
2002 Grand Caravan Sport 3.3litre engine.
I want to flush and fill the rad, but when I open the draincok and the rad cap, nothing drains. In my Haynes manual it says to open a drain vent screw, but there is no such screw on my engine (at least it is not in the location depicted in the Haynes manual (Canadian model?), and not anywhere else obvious to me.)
Why doesn't coolant flow out of the draincok on the bottom left side of the rad?
Is there a trick or secret to this? seems so simple...
Thanks to all responders!
Ian.

(Notes: I put the heater to hot with engine on, tried running engine after opening rad cap and draincok, rad is full of coolant, overflow empty, I even opened the hose at the thermostat to allow air into the system(engine off) and not a drop out the drain).
