May be separate problems. A small fuel leak in the engine may be the source of the 2 scents. A coolant leak may be the source of the poor heat and burning smell. Get it checked out before you have a serious problem. Next time you run the car, shut it off, lift the hood and try to smell where the source of raw fuel is, or any rising smoke.

Antifreeze is used to heat the cab of your vehicle. When you turn on your heat in your cab, it opens up a valve that allows the hot antifreeze to flow from the radiator into the heater core. If there is a leak in the rubber tubes that flow into the heater core, or if the heatercore is damaged, you will smell the antifreeze in the cab of the vehicle. You may need new hoses to the heater core and/or a new heater core.
