I noticed this last few days that after I turned my car off,both the hoses starting to collapsing down until it is almost flat. I could hear the coolant draining back somewhere(The radiator or the engine )? After it cool down a bit the hose will bounce back to its old shape. I don't see a leak anywhere and the temp gauge is showing a little on the cool side ( 140'-160'F ) . I am running a 180'F thermostat.
What could be happening ?

Good call.. The hoses are from 5.0Resto. So I guess they are not the best around. I will drain and clean the overflow tank and see if it is the problem. The cap are about 1 years old. I will pick up a new one asap.

Thank you..Stangnet.
 
The hoses are a symptom, not the underlying issue. More robust hoses might mask the symptom but the issue will still be there.
