If you turned your car’s heater on ten minutes ago and you’re still shivering, that’s your first sign that something might be wrong. However, a few less obvious signs can also warn you that your heater is on thin ice.

Your car heater may need service if...

 

• There’s an unpleasant or foreign smell coming from the heater vents

• The windshield and/or windows are fogging up

• You can see antifreeze leaking in your car’s interior (check the passenger side floor!)

• Your car suddenly needs a ton of coolant
