How Far Can You Drive with a Coolant Warning Light On?

[DiJayden]

You should not continue driving when the car's coolant warning light comes on. In winter, a coolant warning indicates insufficient coolant levels. At this point, you must park the car in a safe area and conduct an inspection. Note that the inspection should only begin after the engine has cooled down. First, open the fluid cap, then loosen the cylinder block and radiator drain switches while the engine is idling at low speed. Precautions for coolant replacement: 1. Same Type: When selecting coolant with antifreeze properties, it's best to use the same brand as the original coolant, or at least ensure it's of the same type (e.g., acidic or alkaline). Otherwise, thoroughly clean the original coolant to prevent contamination or deactivation of the new coolant. 2. Avoid Injury: When opening the coolant cap, ensure the coolant is not too hot to prevent steam burns. 3. Avoid Wetting Pipes: Be careful not to wet the engine pipes during the process, and wipe away any residual water to prevent rust. After replacement, ensure there is no air in the pump and that the liquid level in the reservoir is appropriate after filling the radiator.
