heater core problem symptoms
A leaking heater core usually will cause a much more annoying leak. On most new vehicles, the heater core is inside the cabin of the vehicle. Even if you have an older vehicle with the heater core outside the cabin, leaking fluid can still find its way into the cabin through the ventilation ducts. Having coolant leaking into the cabin of your vehicle can cause all sorts of problems. First, when your car isnât warmed up yet, the coolant will make a mess on your floorboards and possible start the process of corrosion. As the coolant leaks onto your floor it will soak into your carpet and the padding.
