Coolant woes?
'79 351M always drip water out of the exhaust when starting cold. At normal tempatures, when I put my open palm over the exhaust, it blows moist that are not visible.
Looked in the raditor while the engine is running. It flows really well. Water flows fast. But the coolant is brown/yellow. And it smells really odd.
It never overheats, and it opreats between 180-200. Oil is normal, no chocolate milk situation, and thick like oil should be.
Ideas?

Jerm , afriend thought he might be getting very slight amounts of oil in his coolant , so he drained the old coolant , flushed the system , then added clear distilled water to the system so if the oil was present it could be differentiated from the water--none was found so all he had to do was drain approximately 50% of the water , add the same amount of antifreeze back to the system to mix properly with the distilled water for a 50\50 mix which is universally accepted I think.............fd

Yes, I am trying to find things wrong with the truck. I got it not too long ago and I am going over it like a fine tooth comb.
So I shouldn't be concerned? The coolant is just real old and dirty, in need of a flush? What worries me, is the moisture out of the tailpipe.

It gets cold enuf in Maryland to see the "fog" coming out of tailpipes in the winter. It is just steam, or in other words, water vapor. When the engine first starts up the exhaust system is cold metal so when the engine "breathes on it (just like you) it condenses and forms liquid water. The flowing exhaust blows it down the pipe. When you put your hand over the pipe your cooler hand condenses the water out of the exhaust. When the engine warms up it is not a good idea to do this, you can get burned.
That is also why a muffler has a weep hole in it, -to let the water out. The weephole needs to be at the lowest point at the rear of the muffler. Drill a little 3/32" hole if your muffler has been installed incorrectly.

Okay guys, thanks.
PS. It does have a weephole - a bit of soot on the rear section of the muffler helped me to spot it.
