Smoke Coming from Hood of Car

When smoke pours from around the edges of your hood, your first instinct is to worry. That instinct is correct — pull over and turn the engine off.

Visible smoke escaping from around the hood of your car while driving means a fluid is actively burning on a hot engine component. The most urgent concern is overheating — if your temperature gauge is in the red and white steam is coming from the hood, a coolant hose has likely burst or the radiator has failed. Pull over immediately. Running an overheating engine even for a few more minutes can warp the cylinder head and crack the block, turning a $200 hose repair into a $3,000+ engine job.

If the temperature gauge is normal, the smoke is probably oil or another fluid hitting the exhaust. This is less immediately dangerous than overheating but still needs attention — you're losing fluid and there's a fire risk. In either case, don't try to remove the radiator cap while the engine is hot. Pressurized coolant at 220°F+ will erupt and cause severe burns. Let everything cool for at least 20 minutes before investigating under the hood.
