Hi Lisa if it is a plastic one you can try to turn it a little bit but don't force it because it will break there's an o ring on it that is probably worn and can be replaced but go to the help parts section at an auto parts store and you should find one these are pretty easy to get then when you do go to home depot or another hardware store and get an o ring for the old one and give it to dad for a emergency replacement and what's going on with the ranger

Once a petcock starts to leak, there's often no way to fix the old one, especially if it's plastic. Most auto parts stores sell or can order a new petcock for your radiator.

I doubt it.
If you had a vac modulator it would only affect when the transmission upshifts.
Chances are the problem is the valve body or one of the clutches inside the trans.

1990 chevy lumina, idling problem... to rich.... stalling......


check egr valve for vacuum leak. pull hose from manifold. put hose in your mouth like a straw and **** on it. if the valve moves, then it's good. if it doesn't, you need a new egr valve. WARNING, they are fricking expensive! auto zone price $204. NO JOKE
