Replacing a heater core is a necessary repair when the core becomes clogged or damaged, causing insufficient heating or coolant leaks. It involves removing the dashboard, disconnecting hoses, and extracting the old core before installing a new one.
A faulty heater core can lead to discomfort, reduced visibility due to fogging, and potential engine overheating. Replacing it restores heating efficiency, prevents further damage, and ensures a comfortable driving experience.
