What are the signs before an engine blowout?
3 Answers
Signs before an engine blowout include: excessively high engine block temperature, with surface temperature exceeding 90 degrees Celsius; reduced driving power; abnormal noises from piston-cylinder friction, with the frequency of the noise increasing as the engine speed rises. Engine blowout occurs when the temperature is too high, causing the piston to expand and get stuck in the cylinder, leading to engine failure. In severe cases, due to excessive pressure and the piston being unable to move, flames may erupt. Solutions for engine blowout: Ensure the engine is in a cooled state and turned off. Remove the radiator cap to confirm the engine is cool. Open the drain plug at the bottom of the radiator to let the coolant flow into a bucket. Close the drain plug and fill the radiator with water. Start the engine and turn on the heater control system. Add cooling system cleaner and let the engine idle for 30 minutes. Turn off the engine and let it cool for 5 minutes. Drain the liquid from the radiator, close the drain plug, fill the radiator with water, and let the engine idle for 5 minutes.
I've been driving for twenty years, and the warning signs of an engine blowout are quite obvious but easily overlooked. A sudden spike in the temperature gauge with a red warning light is a major alert. The engine noise becomes unusually loud, resembling clanking impacts or hissing leaks. A burnt smell or the odor of scorched oil indicates overheating. While driving, a noticeable drop in power, sluggish acceleration accompanied by shaking, makes the car feel weak and unresponsive. To prevent engine blowout, I regularly maintain the cooling system, checking for aging fans, water pumps, and belts. Before long trips, top up the coolant and avoid prolonged high-speed driving. Engine blowouts are usually caused by cooling system failures or insufficient oil. At the first sign of trouble, pull over immediately, turn off the engine, and let it cool before inspecting to avoid total engine failure.
Young drivers, don't be careless. You can actually sense the warning signs before an engine blowout. If the coolant temperature light comes on for no reason or the gauge needle shoots to the top, be alert immediately. Listen to the engine—if you hear metallic scraping or knocking noises, like it's protesting; or if you detect pungent smoke or oil smells, it's quite dangerous. During daily driving, if acceleration becomes sluggish and weak, accompanied by slight vibrations, pay attention. Prevention is simple: Check the coolant level every month to ensure it's sufficient, and don't delay oil changes for too long. High-speed driving can easily cause overheating—once you notice any warning signs, pull over and rest for half an hour to let the engine cool down before continuing. Engine blowouts often result from cooling system failure or excessive carbon buildup. Detecting issues early can save you from costly major repairs.
