you need a new radiator cap...

when there's low pressure it should suck coolant from the overflow reservoir. If it can't, that means the radiator cap is defective and preventing this from happening.

The radiator cap serves three purposes really:

1.Keeps cooling system from overpressurizing by blowing excess coolant into the overflow resevoir.

2.Keeps cooling system from becoming a vacuum, as in your situation, by drawing coolant in from the overflow resevoir.

3.Keeps coolant from flowing everywhere.. obviously.

Typically, the system is under pressure when it is hot, or at running temperature, and the pressure drops as the engine cools. Replace the cap.

I would also replace the hose now that it's been squeezed like that.

(1) replace the cap witha Honda cap.
(2) if that fails to solve the issue, when the car is cold, pull the hose out of the bottle and run compressed air through the small hose between the radiator neck and catch bottle to make sure it isn't plugged.
(3) If the top hose seems soft, replace it.

Definitely replace the hose the collapsed. If you squeeze it and it makes crinkly noises, the bands inside the hose walls are no longer supporting it and the hose need replacment.
