Why does my car heater smell bad when I turn it on?
If the smell is coming from inside the car only when the heater is turned on, the problem is either with the heater core or the heater hose. If you only notice the smell outside the car, the leak is in the coolant compartment. Reach near the floor on the driver’s side and pull the hood release.
