I found my problem. I hate to admit it but it might help another. I put the thermostat in backwards and I used to much gasket glue around the pump. The glue clogged up the pump when I tightened up the bolts.
I replaced the water pump ( fun) now the water will not cycle. Naturally I think - thermostat.
It was fine b 4. I herd issues could rise because of trapped air. Is that common?
