What is antifreeze smoke?

Antifreeze smoke refers to the vapor or fumes produced when antifreeze, typically containing ethylene glycol or propylene glycol, is heated or burned. This smoke can occur in situations such as engine overheating or coolant leaks, where antifreeze comes into contact with hot surfaces. The fumes can be harmful if inhaled, as they may contain toxic components. It's important to address any leaks or overheating issues in vehicles to prevent exposure to antifreeze smoke.
