M11 coolant system problems.

I'm new to the forum world but I need some help with an m11 cummins..
99 international
ISM cummins
M11-350E
New head, injectors, and fairly new turbo.
Blows water/steam out overflow when engine is running and after you shut it off. Then stop engine light comes on, which weakens the truck( guessing that's the computer defueling to prevent damage). At first I thought it was air trapped..I can hear bubbling once I shut the motor down. It's coming from a small water line that runs from right side of motor beside exhaust manifold to the reservoir. Anybody know what is going on?

 

Thanks for replying!
new thermostat, how do I check the water pump?


On the valve cover it says ISM cummins
on the plate it says model: M11-350E

It's not running hot(according to the dash gauge)

 

Thanks! I just crunk the truck up.. Let it run till it started blowing water out then shut it off. I started bleeding all the air out. When the air pressure started getting low it stopped blowing out water and once all the air bled out the bubbling noises stopped. So I think you may be right.. Could this be why I have excessive amounts of water and oil in the air tanks? dryer is bypassed.

 

What is ESN and where would I find it? Lol
My pa in law told me to switch the air compressor in this truck with The one in his spreader truck. It has an M11 also...that sounds like a lot of trouble.. Is the air compressor hard to take out? Could I just switch the heads or would I need new gaskets to do that?
