If you have these four problems, please stop and check immediately.

Whether the car is good or not depends on the performance of the engine. As the core component of a car, the engine is also the most expensive, and the cost of replacement or overhaul is very high. Engine maintenance is good, tens of thousands of kilometers need not be overhauled, but poor engine maintenance will be very troublesome. In addition to maintenance, if the car has some special symptoms, it will have a fatal impact on the engine if it is not treated in time. For a family car of about 654.38+0.5 million, the engine overhaul should be at least 654.38+0.5 million, and the serious damage will exceed 20,000. Today, the master will talk about what symptoms or driving behavior of the car will damage the engine in a short time.

1. When the oil warning light is on, continue driving.

The light indicates that the oil pressure is insufficient, that is, all parts of the engine cannot be lubricated, or at least enough lubrication conditions cannot be achieved. The reason may be the lack of oil and the damage of the oil pump. In both cases, the oil lamp will be on. When the engine is running at high speed, it always needs enough oil lubrication. If there is no oil, it is equivalent to dry friction between two parts, which will seriously damage the engine in a few minutes. So when you find the oil lamp on, you must stop at once. If you don't find the light on in time, you can hear it in the engine. Without engine oil, the noise of the engine will increase abnormally, and there will be no great damage when it stops. Of course, some cars turn on the lights because the oil pressure sensor itself is damaged. In this case, it is no problem to continue driving. In addition, insufficient oil viscosity and oil deterioration will also cause serious engine wear and even overhaul ahead of schedule. So pay attention to the problem of engine oil, which is the key to protect the engine.

2. Keep driving when the water temperature warning light is on.

The light shows that the water temperature is too high, and the harm of high water temperature is also great. The normal working temperature of the engine is about 90 degrees. At this temperature, the fit clearance between each moving part is optimized. If the temperature is too high, it will inevitably lead to the expansion of all parts, the most serious is the piston, because gasoline burns at its top. The temperature is the highest here. After the piston expands, the gap between the piston and the cylinder becomes smaller, but the piston ring pulls the cylinder, and the piston is directly stuck in the cylinder, resulting in damage to both the piston and the cylinder. This engine needs to be overhauled. In addition, high temperature will damage the cylinder gasket, make the oil path and waterway collude, and the coolant will flow into the engine oil, which will lead to the failure of the engine oil. Poor lubrication will further damage other components.

3. The timing belt was not replaced in time.

Generally, replace the timing belt once every 3 years or 60,000 kilometers. When the service life is up or aging after inspection, it needs to be replaced in time. Once broken, the piston will tilt the valve, the top of the piston will be injured, and even the connecting rod will be forced to bend, so the engine needs to be overhauled.

4. Blind ignition after wading and flameout

Usually driving will inevitably pass through some low-lying areas. If water enters the air inlet, it will be sucked into the cylinder, causing flameout. Most cars are not damaged at this time, but if you start the car again at this time, the connecting rod will bend and the engine will be damaged. Because there is incompressible water in the cylinder, the engine runs, the piston moves upward, the space is not enough, and the starter is stressed, which will bend the connecting rod. The insurance company is not responsible for this part of the maintenance cost.
