Corroded Heat Pipe

It seems that while fixing one thing I notice three other things that need attention. Not complaining because I am able to do most of the wrenching at work...
While replacing the water pump the other day I had to use channel locks to remove my coolant plug that is on the heater supply line. When I got it off all but two threads were left on the plug and the pipe is corroded so bad, that there is no threads left. I had to just spin until it locked up to get it home.
I called George and he had never had to get this part, let a lone know what to call it...
I came up with a simple solution that seems to be working very well and thought I would pass it on. I bought it at Ace Hardware for a couple dollars and have driven about two hundred miles with out a leak. It is just a simple drain plug. I might actually try it in the radiator, because I hate that stupid plastic plug.

Not much help to you if theres no thread left in the pipe (it's not just clogged with plastic right?), but I think the plug is the same as used on the TDi, part number ERR4686.

I replaced both of mine (tdi) with a hydraulic pipe stop, it's a 1/2"BSPP thread, hydraulics people know it as G-1/2. I think theres a US operation of RS Components... part number 727-755 is what I used.

It looks like a Wine Bottle Stopper... What is it made of, is it likely to hold up to the temperatures over time?

It looks like a drain plug for a boat to me. My guess is that it is made of rubber.

It seems to be brass hardware and a rubber stop. I will post if I have any issues in the future. It is just a cheap alternative for me.
