Well, I'm not going to go to the casino or play the lottery for months. I think I used all of my luck with this engine.

I swapped the lower hose - nothing was wrong with the hose except for the normal wear. The upper hose is fairly new and didn't need to be swapped. I drained some water from the block when I took the temp sensor out, and it had a sligh green color to it - so evidently I did have some residual anti-freeze in the block, and that may have saved my butt.

I drove the truck for about 20 minutes, and didn't have any water in the transmission fluid or engine oil. I didn't pull any spark plugs to see if water was in the cylinders, but I couldn't hear any misfiring and the exhaust didn't have alot of steam in it so I think I may have lucked out.

And I did fill it back with 50/50 mix! I think the high idle the other day was because it was cold. Today it ran fine.
