Repair and maintenance of car maintenance, car repair and maintenance

1. Cleaning and maintenance of fuel system.

Under normal circumstances, the car needs to be cleaned and maintained once every 10,000 to 15,000 kilometers, or when you find that the engine is shaking, sluggish and poor acceleration, black smoke, weak and fuel-efficient. Remove gum and carbon deposits from the inside of the system to prevent harmful corrosion, avoid and stop leaks in seals and tanks, and replace old coolant completely.

2. In-depth maintenance of lubrication system.

The main function of the lubrication system is to effectively lubricate the various parts of the automobile engine to prevent excessive wear. Under normal circumstances, the car needs to be cleaned and maintained once every 5000 10000 kilometers, and it needs to be cleaned and maintained once when the engine noise is too loud, the acceleration is weak, and the water temperature is too high. Clean the sludge and other accumulations inside the engine to avoid oxidation thickening of the oil at high temperature, reduce the wear of engine parts, prolong the life of the engine, and improve the engine power.

3. Cleaning and maintenance of cooling system.

Under normal circumstances, the car should be cleaned and maintained once during the change of seasons in winter and summer, and cleaned and maintained once every 6 8 months during normal driving, or once when the water temperature is too high, leaking, and boiling. Remove traces and limescale that cause engine overheating, prevent harmful corrosion, avoid and stop leaks in seals and water tanks, and replace old coolant completely.

5. Cleaning and maintenance of gearbox.

The car is cleaned and maintained once every 20,000 or 25,000 kilometers, or when the gearbox is slippery, the water temperature is high, the gear shift is slow, and the system leaks. Removes harmful sludge and varnish deposits, restores the elasticity of gaskets and O-rings, smooths transmission shifts, improves power delivery, and completely replaces old automatic transmission fluids.

Fourth, the maintenance of the power steering system.

The car needs to be cleaned and maintained once every 40,000 45,000 kilometers, or in case of leakage of the steering difficulty system, after replacing the power steering parts, it must also be cleaned and maintained once.

Remove harmful sludge and paint film from the system, remove steering difficulties at low temperatures, stop and prevent leakage of power steering fluid, remove steering noise, and completely replace old brake steering fluid. "

Summary. Dear, I am happy to answer for you, car maintenance is to ensure the safety of the vehicle. Maintenance includes:

body painting, mechanical circuit maintenance, decoration; And car maintenance includes: minor maintenance and major maintenance. Body Paint:

Body painting is mainly the process of repairing the surface of a car, while painting is the process of restoring the original appearance of a car. Mechanical circuit maintenance: Mechanical circuit maintenance is mainly to repair the mechanical and electrical faults of the car.

This kind of car is not a big accident car.

It belongs to the kiss.

Will it affect safe driving, and I found out that I was deceived after I bought it.

Replacing it with a new part will not affect it, dear.

Hello, dear, <>

<> expand the information for you: The role of car maintenance:1

Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting or replacing certain parts of the relevant parts of the car, also known as car maintenance. 2.Daily car maintenance is very important.

A little carelessness in daily maintenance will not only cause unnecessary damage to the vehicle, but also endanger driving safety. Careful and careful daily work not only keeps the vehicle always new, but also keeps track of the technical condition of each part of the vehicle.

I think it's okay if the front beam is replaced.

Just replace it with a new one and you'll be fine.

As long as it's safe, it's okay to kiss it.

<> "Maintenance Purpose. According to the maintenance period, car maintenance is divided into two categories: regular maintenance and unscheduled maintenance.

1) Regular maintenance includes: daily maintenance, first-level maintenance, second-level maintenance;

Purpose of regular maintenance:

A car is made up of tens of thousands of parts. With use, the performance of functional components, including lubricating oils, gradually decreases due to wear, aging, corrosion, and other factors. Under normal driving of the vehicle, this change gradually occurs in many parts.

Because no car is used exactly the same, it is impossible to predict that every part will wear and age the same. For this reason, the factory prescribes a certain inspection interval to adjust and replace components that can be expected to change over time or with use, which is called "regular maintenance". The aim is to restore the performance of the vehicle to the best condition, prevent small problems from becoming big problems, and ensure the safety of the vehicle, as well as better economy and long service life.

2) Non-scheduled maintenance includes: running-in period maintenance and seasonal maintenance.

1. Maintenance around the engine: 1. The spark plug should be replaced when it reaches 90,000 kilometers. 2. The air filter and gasoline filter should be replaced at 15,000 kilometers.

3. When driving 30,000 kilometers, the fuel injection head and throttle should be cleaned. 4. The engine oil is changed every 8000 kilometers. 5. After serious engine work is bad, the fuel tank and oil circuit should be cleaned, and the fuel injection head should be removed for cleaning.

6. Insist on adding fuel additives, which can reduce the carbon deposition of the valve and the blockage of the fuel injection head.

7. Pay attention to clean the water tank.

8. Do not clean the engine with water.

9. If there is leakage, check it at the service center in time.

Second, the maintenance that needs to be done around the chassis:

1. Pay attention to check the wear and tear of tires frequently, which can reduce the noise of the vehicle.

2. Check that the tire pressure is not too high, which will damage the shock absorber and make the driving uncomfortable.

3. After finding the abnormal sound of the chassis, it is necessary to check the service center, and the fault is generally the damage of the rubber sleeve of the lower arm, which will be dangerous when it is serious, and sometimes the loosening of the iron bottom will also be dangerous.

Three: maintenance around the use of the air conditioning system:

1. The dust filter element outside the air conditioner should be checked and replaced at 15,000 kilometers, if it is too dirty, it will affect the air quality and the refrigeration effect of the air conditioning system.

2. The internal circulation activated carbon filter element should be replaced at 60,000 kilometers, otherwise, there will be peculiar smell in the compartment.

Car maintenance is a general term for car maintenance and repair. It is to investigate the car with no mountain fault through technical means, find out the cause of the failure, and take certain measures to eliminate the fault and restore it to a certain performance and safety standard.

The knowledge involved in auto repair is:

Automobile intelligent inspection, second-hand car appraiser, welding repair, automobile beauty, automobile sheet metal painting, automobile maintenance technology, automotive new energy technology, etc.

Automobile maintenance includes automobile overhaul and automobile minor repair, automobile overhaul refers to the method of repairing or replacing any part of the automobile (including basic parts), restoring the intact technical condition of the automobile and completely (or nearly completely) restoring the life of the car. The minor repair of the automobile refers to the operational repair that ensures or restores the working capacity of the dry beam of the car by replacing or repairing individual parts.
