start the car. let it idle for 1 minute. check the hose. is it HOT? is it Hard? no? good. shut down the car. pull the tank cap, look it over VERY WELL. how old is it? are there any cracks in the seal or the seat/spring pocket?
what pressure is the cap? yours should be a 140KPA I think... (about 22psi) perhaps you could drop it to a 120 or a 100, and see if it vents pressure better.

Just did these tests.
Upper hose had pressure on it (Hasn't been run in 16 hours)
I let the car idle for about 5 minutes before I could detect any heat in the upper hose. It had just gotten about the 40 line and it's around 60 outside. (Not sure what you meant by fluid flowing into the tank, by squeezing it or by removing the cap? Either way there is coolant in the expansion tank)
I have the cap in front of me, it's the 140 and my father got it I think about 4 or 5 years ago. I don't see any cracks in the rubber but i'm going to go to the dealer and see if they have a lower pressure cap (HOPEFULLY that will be the answer)
