I'm having similar problems.
I have tried to bleed the system twice, but I still think I have a bubble.
I run the front end up on ramps, start it up, and open the bleeder screw.
Then I go to the back and both tanks are just about full. I get it up to
2000 RPM and go up front, and feel the radiator (NEW radiator) get hot all
the way up, then the coolant seeps out of the bleeder hole and I tighten it
down. Then I go to the back and the main tank is still full of coolant and
the overflow tank is at max.
Why??? I even tried jacking up the rear end really high to see if the
coolant levels in the tanks would go down, and while they did slightly and I
was able to add coolant, I'm still running 3/4 up on the gauge, which I know
is too hot.
Any ideas?
Perhaps I'm in denial about the air bubble. Maybe it's time for new heads.
But, denial is much less expensive at this point.
