Do you smell antifreeze inside the car or under the hood? See any leaks?


i smell it from inside. and no leaks. i just filled the water/engine coolant tub let it run and the levels never changed. there is no sign of leakage either.


Heater core small leak, steams into car

Sounds l like a very minor leak. Put some Bars Leak into the system. It doesn't hurt your cooling system and works very well on minor leaks.


Put the Bars Leak directly into the radiator. There are instructions on the bottle. Just read and obey.


If you have done nothing to the coolant system in recent past and are not losing cooling fluid, it could be the solenoid motor on the heater box under dash. It closes to push air through heater coil. Feel the carpet under dash and flour mats for moisture.
