A bad heater core is a bigger issue to come across in the cold, winter months, especially if You're dealing with freezing temperature climates.If You have a bad heater core, You should bring Your car in for repairs right away. Driving with a faulty heater core can be risky, as it can lead to overheating and extensive engine damage. Even a clogged heater core can prevent proper coolant circulation, causing Your engine to run hot.
