Replaced the water pump without much ado, however it seems the coolant, all of which went back in ,seems to not be circulating like before, could I have an air lock of some sort and if so how do I "burp it".
The engine is not running hot, if fact a bit cool, seems strange.
Any thoughts

How can you tell it is not circulating properly? If it is running cool I believe I would leave it alone.
