Hi!
I'm trying to drain the antifreeze out of the radiator. When I turn the drain plug. It turns a 1/2 turn til a white mark. No fluid comes out. Do I keep trying to force it to turn counter clock wise or am I supposed to pull on it? I'm just affraid it might break off since it's plastic.
Thanx in advance.
