Kohler generator help

[TwistedSister]

Anyone familiar with the Kohler marine gensets?

I have a 6.5 ESZ that I 'think' is overheating and shutting

down. It runs for about 10 minutes then stops.

water flow is good, air intake is clear, changed fuel filter.

still shutting down. antifreeze level and oil levels are good.

now what?

now for my silly question, what forces the antifreeze to circulate?

There is no circulation pump like you would find on a regular

in board engine.

any suggestions would be appreciated.

thanks,

TwS

I have a Kohler 5E, not the same but similar in operation. I experienced the same problem after changing the coolant. I went online and found pages of forums discussing various problems and how to repair them in the field. I would look on the top of the coolant manifold towards the rear there is a brass bolt. Sometimes air will get into the system when you change the coolant or add coolant if it is very low. The air seems to pocket in the top rear of the manifold and not allow the coolant to flow properly thus making the water temperature too hot forcing the generator to shut down. This brass bolt needs to be loosened to allow the air to escape. Once I removed the air in the system, it ran fine.
