What to do if the engine is flooded with water:
1. If the engine is not seriously flooded with water and only a certain amount of water has entered through the air filter, then you just need to remove the air. Just clean the water vapor on the filter element, cylinder and throttle valve.
2. If there is a little more water in the engine, it will not affect the normal driving of the vehicle, but the engine will make a loud noise. A small amount of water may be mixed with gasoline and engine oil. The owner should change the engine oil as soon as possible and clean the engine-related accessories.
3. If there is a lot of water in the engine and the vehicle cannot start or drive, it is possible that the engine's cylinders, pistons, and connecting rods have all been warped. If the above situations occur, the engine is almost useless and cannot be repaired, and the car owner will have to repair it.e replace with a new engine or simply scrap the vehicle.
How to deal with DIY car maintenance
The reason why the engine water temperature is too low is usually that the thermostat is damaged or the engine fan is damaged. cooling continues to operate.
1. The thermostat is damaged
The thermostat is a component that automatically acts as a valve depending on the engine water temperature. It is usually installed at the radiator outlet and inlet. of the water pump. When the coolant temperature is low, the thermostat blocks low temperature cooling water from the radiator so that it cannot enter the engine water jacket. The water temperature in the water jacket can rise quickly, which everyone often calls a small cycle.
If the water temperature reaches a certain temperature, the valve opensgradually and the coolant in the radiator begins to circulate again, causing the coolant to circulate through the radiator and begin to slowly increase the water temperature. and release into the atmosphere through the radiator. Dissipate heat and keep the engine water temperature at the appropriate temperature. This is the general cycle.
If the thermostat fails, the valve cannot be closed and the coolant is still circulating, the engine water temperature may be too low. Or some cars simply remove the thermostat in order to lower the temperature when the water temperature is high in summer, so the engine water temperature will also be very low.
2. The cooling fan is still running
There is also a cooling fan. For electronic fans, a circuit failure results in constant rotation of the velectronic fan; For silicone oil fans, damage to the silicone oil clutch can also cause the fan to rotate frequently. These breakdowns will result in low water temperatures.
How to drive a car for a long time and how to reduce the number of repairs are all topics that concern car owners. In practice, many car owners lack specific vehicle knowledge, and some do not have any. minor problems often occur. After all, vehicles have many parts and complex structures. During parking and operation, various factors will cause varying degrees of wear, natural loosening or damage to various parts. The purpose of vehicle maintenance is to keep the vehicle in good working order, to maximize its performance and to discover various dangers in time.s hidden to nip them in the bud. There are many elements and contents related to vehicle maintenance, which are divided according to the nature of the work, mainly cleaning, adjustment, lubrication and replacement.
(1) The importance of car maintenance is as follows:
The purpose of regular maintenance: A car is made up of tens of thousands of parts. With use, the performance of functional components (including lubricants) gradually declines due to wear, aging, corrosion and other factors. Under normal vehicle driving conditions, this change occurs gradually in many areas. Since no two vehicles are used in exactly the same way, it is impossible to predict that every part will experience the same wear and tear. Therefore, the factory stipulates a certain inspection cycle, and adjusts and replaces components that may change over time.time or use. This is called “periodic maintenance.” Its goal is to restore vehicle performance to its optimal condition, prevent small problems from turning into big problems and ensure vehicle safety, better economy and longer life. Car maintenance is therefore essential.
(2) Main maintenance items:
1. Thorough maintenance of the lubrication system. The car should be cleaned and maintained every 5,000 km to 10,000 km. the noise is too loud, the acceleration is low, and it also needs to be cleaned and maintained when the water temperature is too high. 2. Fuel system cleaning and maintenance, i.e. cleaning fuel injectors and cleaning carbon deposits from throttle gases which are often seen in auto repair shops. Under normal circumstances, the car should be cleaned andserviced once every 10,000 to 15,000 km. km, or when you find that the engine Clean and maintain once if there is wheezing, lag, poor acceleration, black smoke, weakness and fuel consumption. 3. Cleaning and maintenance of the cooling system. Under normal circumstances, the car should be cleaned and maintained once when the seasons change from winter to summer. Cleaning and maintenance should be performed once every 6-8 months during normal driving, or once when. the water temperature is too high, leaking or when the pot is opened. 4. Cleaning and maintenance of the gearbox (automatic gearbox). Under normal circumstances, the car should be cleaned and maintained once every 20,000 km to 25,000 km of driving, or when the gearbox slips, the water temperature is high, the gear shift is slow or the systemflees me. 5. Cleaning and maintaining the power steering system. The car should be cleaned and maintained every 40,000 km to 45,000 km. If the steering is difficult and the system leaks, it should be cleaned and maintained after replacing the power steering accessories. 6. Cleaning and maintenance of the brake system. Clean and maintain the brake system once every 50,000 km of driving, or if the ABS responds prematurely or too slowly. Remove harmful mud paint film from the system, eliminate the risk of operation failure at ultra-high or ultra-low temperatures, effectively prevent brake fluid deterioration and expiration, and completely replace the old brake fluid .
We can have enough food and clothing by ourselves, and we can also have a deeper understanding of the car in the process of maintaining the car ourselves, so as to better understandour “partners”. You can do it yourself by changing the oil.
Here are some operation steps:
DIY process of changing engine oil and engine filter: ① Use special equipment to lift the vehicle to facilitate the change of oil at the bottom of the vehicle. ② Remove the vehicle's lower skid plate to expose the oil filter element and oil drain screw.
③ Unscrew the oil drain screw on the oil pan. Note that engine oil will spurt out and the temperature will be high when it is unscrewed. Move the oil tank to the vehicle Below, drain the old oil.
④ Use a tool to remove the old oil filter element and rotate it counterclockwise.
⑤ Apply a coat of engine oil to the rubber ring on the edge of the new oil filter and replace it. Tightenthen tighten the oil drain screw, without forcing too much to prevent the thread from protruding.
⑥Add new engine oil to the oil filler hole. Please refer to the vehicle manual for filling quantity.
⑦The final step is to remove the oil dipstick, wipe it with a paper towel, reinsert it into the engine, remove it again, and observe the oil level on the gauge. The reasonable position should be between the lowest line and the highest line of the oil dipstick.
If you can do some maintenance items yourself, you will be more thorough and confident when you do it yourself!
