The heater core is a vital component of a vehicle's heating system. It provides warmth to the cabin and functions similarly to a small radiator, transferring heat from the engine coolant to the air that is blown into the interior of the car. However, like any mechanical part, the heater core is not invincible. Recognizing the signs of a failing heater core can help you act fast, so you can get back to being comfortable during the colder months.
Inconsistent Cabin Temperature One of the first indicators of a malfunctioning heater core is an inconsistent cabin temperature. If you notice that the heat isn't evenly distributed or fluctuates between hot and cold, this could signal a blockage or leak within the core.
Coolant Leaks A visible coolant leak inside the vehicle is a strong indication of a heater core problem. If you find a puddle of coolant (which typically has a sweet smell and is often green, orange, or yellow) on the passenger side floor, it suggests the heater core is leaking.
Foggy Windows If your windows are fogging up more than usual, especially in cold weather, it might be due to steam from a leaking heater core.
