A chemical smell resembling nail polish remover (acetone) in your car is a serious warning sign, most often indicating a coolant leak containing ethylene glycol. This is an urgent situation demanding immediate action due to the risk of inhaling toxic fumes or encountering a flammable liquid leak.
3 Urgent Steps To Take Immediately
- Ventilate Aggressively: Pull over safely as soon as possible. Shut off the engine. Roll down all windows immediately. Get all passengers out of the vehicle and move a safe distance away. Do not linger inside the car breathing the fumes.
- Do NOT Drive the Vehicle: Driving increases engine temperature and pressure, worsening the leak and the potential for vapor buildup or fire hazard. Do not restart the engine. Leave the vehicle off and evacuated until inspected by a professional.
- Call for Professional Roadside Assistance or a Mechanic: Contact a roadside assistance service for a tow or directly call a qualified mechanic. Do not attempt DIY diagnosis or repairs on a suspected coolant or major chemical leak. Inform them specifically about the strong acetone/nail polish remover odor so they are prepared to handle hazardous materials safely.
Why This Smell Signals Extreme Danger
The characteristic "nail polish remover" scent is frequently caused by heated coolant leaking onto hot engine components. Coolant contains ethylene glycol, which produces sweet-smelling, highly toxic fumes when vaporized. These fumes can cause dizziness, nausea, headache, and, with significant exposure, serious organ damage. Additionally, coolant leaks near ignition sources or electrical components pose a significant fire hazard. Ignoring this smell risks severe health consequences and potential vehicle fire.
Remember: Immediate evacuation, turning off the engine, and professional assistance are non-negotiable. Do not dismiss this smell - treat it as the critical emergency it signifies.
