Vehicle engine cleaning and maintenance method.

1. The engine belt generally needs to be replaced after 30,000 to 40,000 kilometers. Usually, if the start belt of the cold car squeaks, it is aging. How to maintain the power steering system of the car? Every car travels 40,000km-45,000km cleaning needs to be maintained once, or the system leaks in case of steering difficulties. After replacing the power steering accessories, it also needs to be cleaned and maintained once.

2. Keep oil, water, air and body clean. If the fuel is not pure, it will affect the supporting parts; if the cooling water is not pure, it will hinder the heat dissipation of the engine, etc. Maintain enough oil, water and air, and do a good job of engine maintenance, so that the engine is always in good condition.

3. Start the engine, check whether the inlet and return oil pipes are leaking, clean at idle for 15-20 minutes, and increase the throttle every 3-5 minutes to discharge the cleaned carbon and moisture from the exhaust pipe. Disassemble the disassembly-free cleaning machine and the engine inlet and return oil pipes, restore the car's oil pipeline, and start the car to check whether the oil pipe is leaking.

4. How toMaintenance of automobile engine Engine maintenance should be done as follows: regular replacement of oil and oil filter, good ventilation of crankcase, regular cleaning of fuel system, regular maintenance of water tank, maintenance and cleaning of fuel system. This engine needs regular maintenance.

Maintenance points of automobile engines, do a good job of cleaning and cooling

1. First of all, clean the air filter. If the air filter is blocked or too much dust accumulates, it will cause the engine intake to be difficult, and And a large amount of dust enters the cylinder, which will accelerate the speed of carbonization in the cylinder, causing the engine to be ignited smoothly, the power is insufficient, and the fuel consumption of the vehicle will naturally increase.

2. Check and replenish the coolant. If the liquid level of the coolant in the storage tank is lower than the minimum scale, it should be supplemented with the same variety of coolant, and if necessary, it should be replaced with distilled water.Note that you must wait for the temperature to drop before opening the lid, otherwise it is very easy to scald people when the high-temperature water sprays out.

3. Use good quality engine oil: engine oil is the lubricating oil of the engine, which can lubricate, clean, cool, seal, reduce wear and other roles on the engine. Only by using qualified lubricating oil can the wear of engine parts be reduced and the service life can be extended.

4. Automobile cooling system: cleaning (1) simple cleaning. When cleaning, empty the old antifreeze, inject water (tap water) into the engine cooling system, and discharge it after starting the engine to rotate for 5 minutes. If the discharged water is quite dirty, the above process should be repeated until the water becomes clear. ( 2) Thorough cleaning.

5. The reason is that the freezing point of water is 0℃. When the engine stops working, the outside temperature willIt causes the water to freeze and expand, causing the water tank to freeze and crack, the water pump to not work, and the freezing of the waterway directly affects the operation of the engine.

Keep the engine clean

1. Maintain enough oil, water and air, and do a good job in engine maintenance , keep the engine in good condition all the time. Keep the oil, water, air and engine clean.If the fuel is impure, it will affect the matching parts; the cooling water is impure will hinder the heat dissipation of the engine, etc.

2. Suggestion: After cleaning, the fuel filter should be replaced in time, and the car should be cleaned and maintained regularly every 10,000 kilometers. Be sure to use better engine oil for maintenance.

3. Instructions for cleaning and maintenance of automobile engines First of all, remove dirt or dust that can be removed with water. Be sure to do the steps to cover the parts before pouring water. The engine-specific cleaner cannot be used on baking paint. The most severe dirt can be dealt with with foam engine special cleaners.
