Hello everyone, today my Focus lost all the coolant, the radiator fan alerted me, the temp gauge didn't budge. I hope i saved the head gasket in time... Anyway, i found a broken metal tube, it moves freely and moving it leads to more water spillage... Can anyone identify what does this tube do?



This is how the tube in my car is moving:
Thanks in advance...

 

I checked again today it seems to be connected to the oil cooler, hope i can sort this out quickly and the engine hasn't suffered any damage...cheers
