I'm changing the coolant on my 1994 Grand Caravan ES with the 3.3L V6.
The radiator drain petcock is on the driver's side, and includes a
short piece of rubber hose. Now the stupid question . . . which way
is the petcock closed? With the lever parallel to the ground
(horizontal), or perpendicular to the ground (vertical). I know this
sounds stupid, but when I originally turned the lever, coolant didn't
flow from the radiator, and it still doesn't. It looks like I need to
pull the radiator and have it checked. I just want to make sure I have
it in the closed position before I take the car to a radiator shop - if
And, once I get all of this done, is there an easy way to "burp" the
system. Unlike other cars I've owned, the 3.3L doesn't have a bleeder
valve on the thermostat housing.
