Re: 1941 180 coolant leak

The original fitting would be an older version of something like this modern draincock and probably threads into a 1/4 or 3/8 NPT tank port. Without being able to get close and personal, am thinking someone replaced the normally found fitting with a solid plug. A plug should be able to be removed providing it has not rusted or otherwise become sealed in place. Just take care to use a backup tool on the tank portion so as not to twist that part out of the tank.
