thank you all for the help with this air pocket.
i fixed it by getting a rad. vacuum tool and pulled it down to -30 lbs pressure and then filled it with coolant and water in one bucket and dropping a hose to the bottom and opened the vavle , and it was full after a min or two.
runs great and no over heating , accept at the heater as it should be.
again thank you all
nice to see there are good poeple willing to help
