How to Deal with Engine Damage?

If the vehicle's radiator is operated incorrectly during normal driving, it is very easy for white steam to emerge from under the hood, a phenomenon we call "boiling over." At this point, the needle on the temperature gauge will quickly rise to the high-temperature "H" mark, indicating that the engine is overheating. The boiling over phenomenon is mainly caused by insufficient water in the radiator, a leaking radiator, or a malfunctioning radiator fan that stops working. The handling method is as follows: The most important thing is to pull over immediately. Note that you should not add water immediately after stopping; if you need to add water, wait until the car's temperature has cooled down before doing so. Do not attempt to continue driving to avoid causing major engine damage. Do not try to open the radiator cap, as there is a high chance of scalding hot liquid spraying out and causing burns. To lower the engine temperature, avoid pouring cold water directly onto the engine block or cylinder head, as this could cause the block to crack due to sudden cooling. Instead, pour water onto the radiator of the engine to dissipate heat, not onto the engine itself. This is because the surface temperature of the engine is very high at this time, and pouring cold water directly on it could cause sudden localized cooling, leading to deformation of related parts. Additionally, there are many sensors on the engine, and pouring water on them could cause electrical components to short-circuit due to water ingress.
If the engine of the car you're driving suddenly malfunctions, based on my years of driving experience, I recommend pulling over immediately and turning off the engine—safety first. Check for any abnormal sounds like knocking, smoke, or oil leaks—these could indicate issues such as seized pistons, bearing damage, or a burst radiator. Never continue driving, as it could worsen the damage. Call for a tow truck or roadside assistance and have the car taken to a professional repair shop for diagnosis. During the repair, technicians may need to disassemble the engine to identify the issue, and costs can vary: minor repairs like part replacements may cost a few hundred, while major repairs or engine replacements can range from thousands to tens of thousands. Regular maintenance, such as timely oil changes and coolant checks, can help reduce risks. An engine failure disrupts travel, so check if your insurance covers any towing or repair costs during this time and plan alternative transportation in advance.
