Would overflow of antifreeze and engine coolant make engine smoke and smell like burning?

Yes, an overflow of antifreeze or engine coolant can cause smoke and a burning smell if it spills onto hot engine components. When coolant leaks onto the engine, it can vaporize and produce smoke. Additionally, the coolant can burn, creating a sweet, acrid odor. It's important to address any coolant overflow promptly to prevent engine damage and ensure safe operation.
