How Long Can You Drive with the Coolant Level Warning Light On?
Source: Chevrolet
Your Chevrolet’s coolant level warning light is one of the most important alerts on your dashboard. It signals that your engine’s coolant is low, which can lead to overheating and serious engine damage if not addressed promptly. At Stokes Chevrolet, we want to help you understand what this warning means and what steps to take to keep your vehicle safe.
What the Coolant Level Warning Light Means
The coolant level warning light turns on when your engine’s coolant—also known as antifreeze—is below the recommended level. Coolant is essential for regulating your engine’s temperature and preventing overheating. Low coolant can result from leaks, a malfunctioning radiator, a failing water pump, or even normal evaporation over time.
How Long Can You Drive?
If your coolant level warning light comes on, you should limit driving as much as possible. Driving with low coolant can quickly cause your engine to overheat, which may lead to warped engine components or a blown head gasket. In some cases, even a short drive can cause damage, especially if you’re in stop-and-go traffic or hot weather.
If you must drive a short distance, do so slowly and carefully, and watch the temperature gauge closely. Pull over immediately if the engine begins to overheat.
Common Causes of Low Coolant
-
Leaks in the radiator, hoses, or water pump
-
Cracked or damaged coolant reservoir
-
Failing radiator cap
-
Old or contaminated coolant that no longer circulates properly
What You Should Do Next
-
Turn off the engine: Let it cool down before opening the hood.
-
Check the coolant level: Only check when the engine is cool to avoid burns from hot coolant.
-
Add coolant if needed: Use the type recommended in your Chevrolet’s owner’s manual.
-
Inspect for leaks: Look under the vehicle and around hoses for visible signs of fluid leaks.
