Why Does My Car Smell Like Maple Syrup

This can be a serious issue if not addressed promptly as it can lead to engine damage and even health problems.

The sweet scent of maple syrup can signal a few things, but the most common reason is that a coolant leak has occurred.

Unfortunately, a coolant leak can lead to engine damage if not resolved and can even pose a threat to the health of drivers and passengers.
