If your going through coolant then you have an internal head gasket leak you smell coolant because its getting into cylinder and burning
heater core leaking
Your gaskets are leaking and you are leaking antifreeze inside the manifold. Same thing happened to me on my silhouette and cutlass. The problem is the orange anti-freeze eats the gaskets. Will cost $2,000-to-$3,000 to fix. Sorry!
Your heater uses somthing akin to a mini radiator to transfer heat from your engine to the cars interior. However, if you're smelling antifreeze, you have some type of leak.
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.
if it rear air and heat it could be the line carring the antifreeze tho the back heater core.
This will happen if you have a slight leak or leak in your heater core. Have your heater core checked for leaks.
you probably have a leaking heater core....you can replace it or bypass it
Typical of the heater core leaking. Overheat because of low fluid and pressure. Foggy windshield due to heater core leaking and will smell antifreeze in the car.
you will smell antifreeze, you may or may not have heat, you could run out of anti freeze
Leaking heater core.Leaking heater core.
It's either stopped up (no heat) or leaking. If leaking you will smell antifreeze (sweet sickening smell) and it might fog up your windshield with the defroster on. Leaking alot, the carpet is wet. Keep an eye on the antifreeze level.
I could be there is not enough coolant in the system, therefore, not totally submerging the temp gauge sensor in hot fluid. check water pump for leaks, heater core, or radiator, smell around for a " sweet" smell under passenger side dash, that's where the hearer core is, and antifreeze has a distinct sweet smell..
