Maintenance is not timely
Do not delay regular engine maintenance
According to experienced auto mechanics, among the maintenance cases they handle, engine failure caused by poor maintenance accounts for about half of the total failure. This shows that engine maintenance plays a vital role in extending vehicle life.
Owners should not be lazy about regular service. In addition to following the regular maintenance period for engine maintenance, drivers should also inspect relevant engine parts after driving through especially humid or dusty areas.
Timely maintenance does not only mean replacing items on schedule. It also means paying attention to the environment the car has been driven through and checking whether dust, moisture, or harsh conditions have affected the engine and its related systems.
Engine temperature is afraid of high and low
Engine temperature that is too low is also harmful
Some owners believe that the engine is only afraid of high temperature. They think overheating is the only temperature condition that damages the engine.
In fact, low engine temperature can also be very harmful. For example, some owners blindly remove the thermostat because engine temperature is high. After the thermostat is removed, coolant can only make a large circulation and cannot adjust the cooling intensity.
This makes it difficult to ensure that the engine works at a suitable temperature. The engine may often run in a low-temperature state, causing a decline in engine power, accelerated wear, and increased fuel consumption.
The correct approach is to follow the normal temperature guidance in the car manual. Keeping the engine within its intended working temperature range helps protect service life.
Long idle
Avoid long idle periods that increase carbon buildup
When a car is idling, it is in a dense state of oil injection. During idle operation, the valve opens only very slightly, and the injectors spray a higher concentration of fuel to ensure engine operation.
This makes idling more likely to cause carbon buildup than normal driving or high-speed driving. If the car idles for a long time, engine carbon buildup will become more serious.
Over time, this affects intake and exhaust efficiency. Direct-injection models are the most serious: vehicles that often idle can show obvious black smoke during cold start.
Air filter, intake ducts and crankcase sludge
Keep air intake clean and control oil sludge
Air filter blockage and dirty intake ducts
The engine intake system is mainly composed of two parts: the air filter and intake ducts. If the vehicle is often driven in dusty areas or areas with poor air quality, owners should pay attention to cleaning the air intake ducts to ensure smooth air intake.
The intake duct is very important for normal engine operation. If the intake duct is too dirty, efficiency decreases and the engine cannot run within its normal output power range. This increases engine wear and aging.
It is also important to buy genuine air-filter parts provided by the original manufacturer and to choose good quality. Try to drive less in dusty areas, and remember that the air conditioning compartment should also be replaced when needed.
Excessive crankcase sludge
A small amount of sludge can be suspended in the oil. When the amount becomes large, sludge can precipitate out of the oil and clog the filter and oil holes. This makes engine lubrication difficult and increases engine wear.
To reduce sludge production, use quality lubricants and replace them according to the manufacturer’s maintenance intervals.
Choosing oil products is delicate. More expensive oil is not always better. Oil should be selected according to the highest and minimum temperatures of the vehicle location, the grade of the vehicle, and the condition of the car.
Small maintenance mistakes can become serious engine problems
The issues above can all bring a certain degree of damage to the engine. Drivers should pay attention to maintenance timing, correct engine temperature control, idle habits, intake cleanliness, and oil sludge prevention.
If you are not sure how to judge a problem, it is safer to keep regular engine maintenance at an auto repair store and listen to the advice of maintenance staff. You can also visit our website to learn car maintenance skills and find useful tools for car repair.
