I am loosing antifreeze from the coolant system. I have searched all over the vehicle and drive way and can not find any antifreze. The oil is clean. The is no moisture coming from the exhaust. With the addition to all of this it smells like antifree in the cab, this leads me to think it is the heater core. Is it possible for it to get this smell and not leak enough to see?

apparently the o rings to the hose(s) to the heater core can go belly up - this is what i would look at 1st

best of luck

A heater core leak may only leak when under pressure and escape as steam and not liquid. Give it time you get wet!
