This is not necessarily true. Plain, clear water dripping from the tail pipe is a normal function of the catalytic converter. When it is the color and smell of coolant is when its time to worry.Is your exhaust white? Is water dripping from your tail pipe? Those are sure signs of a blown head gasket. If you are losing coolant that fast it must be going somewhere.
Excellent point. If its a lot of coolant running out the exhaust, surely the catalytic converters would have triggered a code and CEL, besides leaking a lot going missing means it should manifest itself very obviously either in the oil, or out of the exhaust.Seen that happen. Yes, water dripping from the tailpipe is normal(unless it's a LOT of water). If you're worried about water in your oil, check your dip stick. If it looks like chocolate milk, that's bad. Watch for white smoke out the tailpipe. Are you missing(engine rough)? Any other symptoms or is it just running through antifreeze. If it's ONLY running through antifreeze, replace your radiator cap. Seen that work once or twice, and it's cheap. When you park check to see if you hear any bubbling.
