Toyota Prius v Heater core

Description

The heater core in the Toyota Prius $\text{v}$ is responsible for heating the cabin, but when it fails, common symptoms include a lack of heat, a sweet coolant smell, or foggy windows. Because this component is buried deep behind the dashboard, replacing the heater core is an extensive job with repair costs often ranging from $\$1,150$ to $\$1,900$. Regular cooling system maintenance is recommended to prevent clogging or corrosion issues.
