I have to add coolant, I have checked with dealer and said pressure tank is leaking, replace the tank , still problem is there, I told them when I turn on heat, my eyes are burning too, they ask me to replace the tank, so I did, coolant still leak, so diagnosis is not wright. Eyes burning was happening since long time, but I notice in December, I was going to eye doctor,.
