How can you tell when heater core is bad or leaks?
my front windsheild fogs up all the time no matter how warm the tempurature is outside could the haeter core be leaking anti-frezze or is it somthing else.
If your heater core is leaking you should be having to add coolant to the engine and the heater won`t work correctly and there is coolant on passenger side carpet.
