I smell antifreeze when I run my heat and/or defroster…but BOTH still WORK fine! There is no leaking of coolant into the cab of the car or through defroster vents. It’s a 1995 Isuzu Rodeo with 155K miles on it

Smelling antifreeze when I run heat

I’m beginning to think you are correct. FOR Clarification: a small leak in the Heater Core? Or a small leak in the Radiator? AND, can I use the heat/defroster without damaging the car-car?
