unidentified part
What is this "water valve" for? See item 1 below. I am sure this is not the thermostat/waterpump.
I found that my expansion tank was under excessive pressure so that it leaked at the gap between the tank and the lid. This part is making continuous clicking noise when the coolant system is turned on. I am inclined to replace this one but have to understand what it actually does..
Thanks,

Oh, it is 4.4i. I bet 3.0i has the same but probably in a different location.
