When a heater core needs replacing

The heater core is a small radiator behind the dashboard that transfers coolant heat into the cabin. It can leak over time — typically from the aluminium-core-to-plastic-shell seam or from corrosion-induced holes. Symptoms of a faulty heater core: cabin is damp and windows fog easily, cabin carpet has a sweet smell (coolant), the blower doesn't produce warm air, or coolant level drops without external leaks.

Why do heater cores leak?

External rusting of the heater core is caused by poor coolant — when its corrosion-inhibition capacity is depleted, the core starts eating from inside. The core can also be damaged by freezing — if coolant has too much water (wrong mix ratio), ice expands and splits the aluminium. Regular coolant change with the correct mix is the best prevention.
