Can You Drive When the Car Coolant Light Is On?

[VanAllison]

You should not drive when the car coolant light is on. If the coolant light is illuminated, you should: 1. Check whether the coolant level in the coolant reservoir is between the max and min marks or directly inspect whether the radiator has sufficient coolant. If the coolant is insufficient, replenish it. If the coolant level is adequate but the warning light is flashing, you may continue driving normally; 2. Inspect the radiator, upper and lower hose joints, inlet and outlet valves, water pump and hose connections, and thermostat housing gasket in sequence; 3. Pull out the dipstick to observe. If there is water in the engine oil, it indicates that the inner walls of the cylinders or intake passages are cracked and leaking, or the cylinder head gasket is damaged and communicating with the cylinder, causing leakage. In this case, call a repair shop for a tow truck; 4. If coolant easily splashes and is lost from the filler neck, it means the air valve in the radiator cap has failed. Replace it with a radiator cap of the same model; 5. After emergency treatment of the coolant, avoid low-speed driving under heavy load as much as possible.
