If it's a nauseating sweet smell, it means your heater core is leaking into the air box. It will have to be replaced.

SOURCE: Car Heater smells strange

Its not from the antifreeze its just that you probably don't use the heater at all and when you do use it it gives out that smell you should try replacing the air filter on it that should solve your problem

SOURCE: car has gas smell when heater is on

my question is do you smell gas when outside the vehicle? chances are it is pulling "fresh air" from outside the vehicle and might be pulling vapors due to thew fact you have a gas leak under the hood. check your engine while running and if a gas leak is seen. turn it off imediately and repair it. do not drive it until then. happy holidays

Churping fan noise inside car behind the middle heater/air vent and a smell of burning oil or anti-freeze coats me and my clothes while inside car Help Help.


Not familiar with Saab at all, but on every other car made, if you smell coolant inside the car and a fog covers the windows, the heater core needs to be replaced. Depending on the design of the heater box that contains your blower motor and heater core, leaking coolant may be destroying your blower motor, and causing the noises and metal smell.

Either its the heater core or the thermostat


your heater core is definitley leaking and your blower is pushing the vapor into the cabin. It will only get worse. You can minimize the smell by not running your heater or defroster, but you wont prevent the coolant from leaking and potentially getting worse. Sorry to say, the core will need pulled and repaired or replaced. Sometimes stop leak additives will solve the problem if its not too severe. I have never been a fan of them, its only a band aid in my view. also if u got pets afoid leeting they smell the antifreeze very toxic can kill pets easily. hope this helps. rate above 4* cheers

Front heater not heating properly have added coolant also can smell coolant at times rear heater was not working but now it began to heat


It stopped heating because it was low on coolant and the hot coolant flowing through the heater core is what gives you heat. As for the smell 9 times out of 10 if you are smelling the sweet smell of anti-freeze in the vehicle it is the heater core. see if the passenger floorboard is wet or damp. If it is , the heater core has failed.

Car Heater smells strange


from he Popular Mechanics site if the smell in your car is like maple syrup:


(1) SMELLS LIKE: MAPLE SYRUP
WHEN: After the engine has warmed or possibly even after it's shut off for a few minutes.
THE CULPRIT: Coolant containing sweet-smelling (but toxic) ethylene glycol is leaking from somewhere. It could be coming from a radiator or heater hose, a failed intake manifold gasket or cylinder head. It might be coming from a leaky radiator cap or the radiator itself, especially if you smell it outside the car. A strong odor inside the passenger compartment probably means a bad heater core.
