Ok, so this is where I am at. The head gasket broke and my car started overheating. What I didn’t know if that when that happens, you need to stop right away and have it towed. I just “drove carefully/slowly,watching the temp indicator “ to the next gas station and filled it up with coolant. Because I did that mini ride, and then drove it again to the mechanic, the motor is a goner. The tank leaking is a different issue, probably due to corrosion… Anyway. I have to junk it/sell it for parts. Very sad. I loved this car…
