Posted January 17, 20169 yr Owner 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.
January 17, 20169 yr Staff 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.
January 17, 20169 yr 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.
January 17, 20169 yr Staff Joe, can you get it to spin using some spray lube? I think a new one on the bench would be good first.
January 17, 20169 yr My personal technique is to accidentally the whole thing while removing it and buy a new radiator.
January 17, 20169 yr Author Owner 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. Edited January 17, 20169 yr by Mopar1973Man
