View Full Version : Drippy drain Cock

The one at the bottom of the radiator ...not what you're thinking sick fuck.

the drain cock at the bottom of the radiator has a thumb screw on it and it just barely dribbles. Like if I leave it parked in the same place and don't start it for a couple days you'll see just a few drops of coolant on the ground. It's not even enough to notice a lower level in the radiator when you take the cap off. I have tightened it as much as it will go, even with a pair of pliers to be sure it was all the way closed and it still seems to dribble just a little. so is there some kind of a seal in there? or does the plastic of the nut/valve just wear out after time?

There is at least one o-ring in the assembly.
