frost plug removal/block heater.

Drain the coolant if you haven't already done so, and heat it and the surrounding area with a propane torch. This will soften the thread sealant enough to let you remove the plug. You want to get it heated to ~250F or so; almost too-hot-to-touch (the ol' scorched finger gauge). Be sure to reapply loctite "red" or similar when you put things back together.

Thanks, I thought a hot engine from driving would be good enough but I'll try the torch. TG

"0" land, where about? I'm in Billings MT. Operate HF mobile 5 hours a day and have the 146.76 repeater. TG

Should this approach fail; start with a hot engine then apply a lump of "dry ice" to the block heater. OR leave it in place and install an in-line engine heater in one of the heater hoses.

Good Luck Walt
