I was under my van looking at the radiator hoses that connect the
radiator to the plastic pipes that run the length of the van.
The van was cold, and I was squeezing the hoses to see if they were
serviceable. However, it seemed like there was no liquid in the hoses as
there was no resistance when I squeezed them.
Is this a valid indicator that there is air trapped in the system?

Has anyone ever tried placing a small length of clear plastic
heat-resistant tubing midstream of the hose as a window to see if there
is any air in the system?
If I remove my bleed bolt on the radiator with the motor running, there
is plenty of coolant to leak out.
