Well, I found out why I was loosing coolant. The drain plug just came out of the radiator. It looks like the threads are stripped off of it. Anyway, I need to get it back up and running while I'm waiting on a Griffin. So, question is... What kind of plastic are the tanks and plug made from? My intentions are to get a new plug ($?) and use a good adhesive to glue it into the tank until my "real" radiator comes in. Any suggestions on how to do this or what to use to attach the plug.
