If my heater core is leaking is it OK to bypass it by connecting the hose going into the core and the hose coming out of the core together so the coolant will flow out of the engine and back to the radiator.
Hello there, thank you for asking about your car. You can bypass most heater cores this way to keep the engine from losing coolant until the core can get replaced. If your engine loses too much coolant, a technician from YourMechanic can come to your home or office to top off your coolant.
