One way of checking whether you need to change the hoses is to remove one of the small hose and check it.. see whether it have turn hard or brittle.. if it is then the other hoses behine the engine would be about the same condition... better to change the whole set at the same time. it will save you a lot trouble in the long run....   here is my condition la, a bit near what u have described...... the water coolant keep dropping, i think everytime i heat the car enough like pussy mention the hssssss sound will appear, i can clearly see one of the large hose/connector is "bleeding" (can see some bubbling last time, but then after thigthen up a bit now sometime can hear the hssss sound la, sometimes can't)........ actually how fast does the water can loss through a small bleeder like that????i heard a very similar noise i from the back of the engine...... and jarence, there is a small hose(1.5cm in diameter) just underneath the main big hose from the radiator, are u referring those small hose??????ya another thingy, after i drive i check the level of the coolant is about the min level on the reserve tank without opening the cap, but then when i try to open the tank, a lot of gas will release.... wow, the level of coolant went up significatly.... is that normal???????about the air lock, i think we can bleed with the small screw beside the radiator cap?????</blockquote>
