i have a nice anti-freeze smell in the cab right now and i cant trace to where i am leaking anti freeze. could it be the heater coils and what should i check. the smell is to the point where you can pretty much taste anti-freeze.

 

If it's in the cab, it's the heater core.

The hole is probably at the top of the heater core and releasing more vapor than liquid. Either way you gota change it!
