Butane,
so far, I've seen numerous suggestions of things to try. the only responses I have seen from you are "I know it isn't that" or "there isn't any air" (how do you know??) or "I think it should...."
The point is... if you don't know what it is, you can't possibly know what it isn't.
You are stating that there IS no air in the system, but you were asking about whether or not it burps over time (indicating that you were under the ASSUMPTION it would have no air...)
People can only offer so many solutions, but if they are ALL shot down by you simply by reading and replying, instead of getting out there and trying it (even if you think it "should" be fine) then people are going to run out of ideas REALLY quick..
So.. I suggest the following:
check the strength.
Check for air in the system my manually massaging the hoses as described above.
check the coolant fan operation (high and low)
We'll go from there when you say you've done those things..
