I have a smell of radiator hot coolant smell coming in the air vents, smell is like burning smell but see no leaks any wheres on the outside. What could this be? Iam thinking heater core could that be it? Thanks

I feel that you do have a small leak in the heater core, do not attempt to use any stop leak products as this will cause more problems, get a cooling system pressure test done with the heater on and if it is leaking get it fixed correctly.
