Can a bad heater core cause coolant to leak?
Coolant/antifreeze contains corrosion inhibitors that coat the surfaces inside the cooling system, including the heater core. When the corrosion inhibitors are depleted, the cooling system can become corroded, filled with contaminants and may even start to leak.
Does coolant flow through heater core?
A heater core is a radiator-like device used in heating the cabin of a vehicle. Hot coolant from the vehicle’s engine is passed through a winding tube of the core, a heat exchanger between coolant and cabin air.
Where would a heater core leak?
