The presence of a sweet, pungent odor emanating from a vehicle often indicates a coolant leak. Ethylene glycol, the primary component of most antifreeze formulations, possesses this characteristic scent. Identifying the source of the odor is crucial for preventing engine damage and ensuring safe operation.
Addressing this issue promptly is essential because coolant loss can lead to engine overheating, which may result in costly repairs. Furthermore, ethylene glycol is toxic if ingested, posing a risk to both humans and animals. The widespread use of antifreeze in internal combustion engines necessitates understanding the potential risks associated with its leakage.
