Radiator drain plug fix.

I like that.

Another tidbit... I've had this happen to a customer truck and it was so simple to fix. If you happen to have o-rings form A/C work or just a o-ring kit you can swap them out in no time flat.

It would be nice if you could change the valve to a brass ball valve somehow with the right fitting to adapt to the O ring female fit on the radiator. But then I am a dreamer...... someday I might try that with some plumbing fittings.

After fixing it, I haven't touched it since.  I use a chunk of tubing and siphon it out the top.

And yeah, I just grabbed a random O-ring that looked about right.

I can't get my drain plug out. Afraid I'm going to break it off.

Joe, can you get it to spin using some spray lube? I think a new one on the bench would be good first.

My personal technique is to accidentally the whole thing while removing it and buy a new radiator.

Silicone spray lube will work for getting it freed up.

It a twist, pull out, then twist again... To drain normally.

At that point once its drained out just twist a little till it stops then pull out gently.

I've done this twice now repairing drain plugs one on a 2nd Gen and one on a 4th Gen. So technically the article is should be relocated to "General Cummins" being does work for 2nd Gen, 3rd Gen and  4th Gen.
