Heater hoses are rubber hoses that circulate engine coolant to and from the heater core, which is the small radiator that provides heat for the cabin. They typically extend from the engine to the firewall, because the core is located inside the vehicle’s dashboard.
Can you drive with a broken heater hose?
You can still drive on with the condition; however, you should not, for a long time. The heater core uses the engine’s coolant, and a faulty heater core affects the cooling effect which then raises the temperature. Not curing the issue and continue to drive the vehicle this way can lead to further engine damage.
