Antifreeze smell

[sweet99]

Every once in a while I get a faint smell of antifreeze in the cab. I don't seem to be losing any antifreeze from my resivore though. Does anyone have any ideas on what the problem could be? I'm hoping not a head gasket!!

Heater core.

I would think it would leak or something? How hard us the heater core to change on a dmax

Hard the first time.... Takes awhile, you gotta pull the dash. Does your windshield get a whitish residue that smears when you wipe it off on it?
