Re: No Coolant flow in 5.9
You will need to try and fill it more I believe. There should be no air
at all in a cold system. As it expands when hot, it goes to the over
flow and comes back when it cools down so the rad is always full to the
top.

Re: No Coolant flow in 5.9
I have fluid up to the thermostat hole, and I tried squeezing the air
out of the upper hose while filling the rad. Problem is that the hose
is higher than any spot I can fill it. Yes I did find the sensor,
have to replace it yet, but I know I haev a probelm other than that
with the flow, so I'm still working on it.

Re: No Coolant flow in 5.9
I always install flushing tee. It makes burping the trapped air an easy
task.
http://www.honeywell.com.au/business...one/flush.html
The kits only cost $3-$4
Here is the tee installed.
