Will the Engine Burn Coolant?

The engine does not burn coolant. However, if the engine frequently overheats, the coolant may boil and vaporize, causing a significant amount of coolant to escape through the radiator cap's steam valve, leading to coolant loss. In such cases, it is necessary to identify the cause of the engine overheating and address it accordingly. Vehicle coolant generally needs to be replaced every 2 years or 40,000 kilometers, which is just a reference interval. For commercial vehicles with higher mileage, the replacement interval should be shorter. Since driving conditions vary for each vehicle, the replacement should be based on actual usage. Regularly check the coolant level and top it up if it is low. If suspended particles, sediment, or signs of deterioration or discoloration are observed in the coolant, replace it immediately and flush the system. How to determine if coolant is low: Observe the coolant warning light on the dashboard. If it lights up, it likely indicates low coolant, though it could also be due to excessively high engine temperature. Check the coolant reservoir. If the level is below the minimum mark (MIN), do not continue driving and add coolant promptly. Inspect the coolant level markings on the overflow tank. The normal coolant level should be between the maximum and minimum marks. If the coolant is below the minimum mark, it indicates a shortage.
As an experienced driver, I've encountered a similar issue before. My car's exhaust pipe was frequently emitting white smoke with a sweet smell, and I noticed the coolant level was dropping rapidly. After taking it to the repair shop for diagnosis, they found the engine head gasket was damaged, causing coolant to leak into the combustion chamber and get burned. This is definitely not normal - engine design keeps the cooling system completely separate from combustion areas. If ignored, it can lead to engine overheating, piston damage, or even more serious failures. I remember that repair cost me over a thousand yuan plus replacement parts. So always pay attention while driving - if you notice unexplained rapid coolant loss or white smoke, get it checked immediately before major problems develop. Coolant's primary function is temperature regulation, not fuel - burning it is purely a malfunction indicator.
