Legacy_of_doom

Hi All, Dad's '96 legacy is losing water through a slow leak somewhere, and subsequently overheating from time to time. Its been in to subaru a couple of times but they cant find where its leaking, and in reality, I dont think they give a ************. The car is getting on a bit now and its not important to their customer service record. Anyway, is there anything in particular its likely to be? Common weak point in the cooling system? Cheers, Mike.
