2001 325i. I have been losing coolant and my car overheated a couple of days ago while the heater was on. As my car heats up, I can see pressure forced air coming out of a connection to the radiator. I can relieve this by loosening the pressure release srew on the top hose. It seems to lose coolant in large quantities only when the heater is on. Any suggestions?
