Sounds like a normal system to me...the upper hose will get hard once the car warms up and the system pressurizes. Some coolant (~8-12 oz) will be pushed into the coolant bottle due to coolant expansion...when the car cools off, suction pulls the coolant back into the rad. If your coolant gauge is staying in the 4-5 'clock position and the above happens, that is a sign of a healthy coolant system.
I don't mind helping man, but you need to understand I'm (we) are trying to diagnose this without being there. You need to "paint a picture" in words as to what's happening. Otherwise you'll get all sort of side track answers...I'm trying to help you, help yourself here
