What happens if I continue driving with a coolant warning?

You can continue driving with a coolant warning as long as the water temperature is normal. However, it is recommended that you go to a 4S shop or repair shop for maintenance and inspection as soon as possible. Meaning of the warning light: The warning light is a reminder that you need to add coolant. However, if the water temperature reaches the red line while driving, you should not continue driving! If you cannot add antifreeze temporarily, consider pulling over and letting the engine idle to lower the water temperature and avoid causing secondary damage to the engine by continuing to drive. Additionally, when adding coolant, be sure not to mix different types. Only add the same type of coolant as the one in your vehicle.
That day I was driving out of town when the coolant warning light started flashing. I didn’t pay attention at the time and ended up suffering big losses. The car kept getting hotter—first the dashboard showed an overheating engine temperature, then white smoke started pouring out, which totally panicked me, so I quickly pulled over. Later, when a mechanic checked it out, the engine block was nearly cracked, and the repair cost me almost ten grand. The reason was simple: insufficient or leaking coolant caused the antifreeze to fail, preventing the engine from cooling down. The metal parts expanded from heat and deformed, and over time, this could lead to engine seizure or even a fire. So if a warning light comes on, never push your luck—pull over immediately, turn off the engine, and check the fluid levels. It’s best to call a tow truck and avoid driving further. This lesson is one I’ll remember for life to avoid wasting money and risking danger.
