Freeze Plug Size

I think that the freeze plug behind the driver side motor mount maybe leaking. We're not actually doing Thanksgiving until tomorrow so I thought I would use tomorrow to investigate.

Does anyone know the size off the top or do you have to measure each one to be sure? It would be nice to have one on hand.

Thanks

Get the expandable copper plug for this. Makes it MUCH easier to drive in in situ. Now, if you don't mind pulling the motor, then a regular brass plug can be driven in. The one behind the driver side motor mount is just a trifle easier to install than the one behind the passenger side mount. You might try some copper flake stopleak for now too, if the thing isn't leaking MUCH yet.... It helped with mine.
