1997 4.6 expedition heater core leaking
 

I can smell anti freeze coming from front vents. I will assume the heater core is leaking. No fluids gushing out anywhere. If it were the head gaskets, I would expect to see white smoke from exhaust and not smell it in the truck. Now the million dollar question, will I have to remove the dash board to chang the front heater core? any pictures appreciated.

Thanks
