Stuck Radiator Drain Plug

Postby Dave.49.cub » Fri Jun 04, 2004 2:36 pm

I was trying to drain and flush the radiator on my 1949 Cub and man that drain plug is stuck tight.

I have tapped, pounded, sprayed Liquid Wrench, heated with a propane torch and no luck. I have grabbed it tight with vise grips to try and get it to move with no luck.

I'd sure appreciate any advice, comments or tips from anyone.

Dave:

The drain plug on Ellie was all mashed to uselessness and froze tight in the casing.

We tried heat, vise grips, stick welder and nothing worked. As I said in my post - That Special Feeling, we finally were able to weld a nut to the damaged plug with a MIG welder.

A judicious tap or two and a little elbow grease with a pair of vise grips and presto pop off it came. It is a little difficult welding upside down, but it is doable.

Try that - should work
