Overheating trouble shooting

Production of water by engines is why stock mufflers have drain holes drilled in them and why the muffler gotta out

I am use to water but the volume coming out was most I've ever saw come out of the truck.
It was a greenish hue so I am sure its coolant.

I had the water pump and fan clutch replaced in Feb 2012, but due to the great reliability of my truck it only has 7k miles on it.

When I did the pressure test over 45 minutes it dropped from 15 psi to 10. The test kit said a gradual drop is pressure is results of a slow leak. So I think some coolant got displaced, somewhere, and exited through the exhaust.

Once again thanks for the insight, and helping me try to figure this out.

If coolant is coming out the exhaust should be white smoke depending on size of leak, I do not see green in the pic

Not sure on d2 but d1 you remove the coolant cap and read fill plug then get the pass front wheel up on a ramp or similar to bleed off air, even then it can be uncooperative sometimes

Its hard to tell the color from the pix. There was a bit of white smoke a few days ago.
I went thru that bleeding procedure. There is no sloshing sound so I am sure the system is bled.
I pulled cyl. 3 spark plug, and it looks like there is condensation in there.

On a side note I owe you a beer Tom. This has me scratching my head, and I post to get a outside opinions.

These things can be a real pain so we can all use lots of help, and maybe our heads examined for keeping them
