How to maintain a 250,000 kilometer car, and how to maintain a 200,000 kilometer car?

Normal maintenance expenses are gradually increasing Under normal circumstances, vehicle maintenance expenses are not high, even if it is a high-end model of 200,000 yuan, do a maintenance of engine oil + filter, a total of 300-500 yuan; Do the maintenance of engine oil + three filters, a total of 500-700 yuan. Taking a Japanese car with a maintenance cycle of 5,000 kilometers as an example, it will drive 20,000-30,000 kilometers in one year, and the normal maintenance will only be 2,000-3,000 yuan. Of course, as the accessories age, the maintenance cost will also increase.

However, for different models, after the car mileage exceeds 30,000-40,000 kilometers, the car needs to do a comprehensive maintenance, at that time, on the basis of replacing the oil + three filters, it is also necessary to replace the spark plug, transmission oil, etc., and the mileage is more than 60,000-80,000 kilometers, it is a large replacement cycle, and the timing belt and other high-cost components need to be replaced, in these two stages, the maintenance cost is higher. Higher Expenses for Abnormal Maintenance Accessories for abnormal maintenance** tend to be more expensive than for normal maintenance**. Because the abnormal maintenance parts are not within the scope of normal maintenance, but they also have a certain service life and need to be replaced from time to time.

For example, the general life of the front brake pad of the car is 30,000-50,000 kilometers, but if you often drive in the congested road section of the city, or the owner does not have good driving habits, the life of the brake pad will be greatly shortened, and it may need to be replaced after 20,000 kilometers, even if it is more economical Fukang, a pair of front brake pads are about 400 yuan, and the cost is even much higher than the daily maintenance, therefore, developing good driving habits is one of the best ways to save maintenance expenses. The replacement of safety accessories can not be saved Car safety is related to life, and places that should not be saved must not be saved, such as the replacement of safety accessories, such as brake pads, tires, and timing belts. Some car tires are cut by roadside steps, and the tire wall is thin, and the owner may think that it is a trivial matter, and he can drive it.

However, worn tires will affect the stability of the car, and driving in the city is relatively fine, once the car is driving on the highway will be very dangerous, and even accidents may occur. In addition, like timing belts, many manufacturers are forced to replace, and some brands have very high replacement costs, but timing belts are a "bridge" in engine work, and the force is transmitted to the corresponding parts under the drive of the crankshaft. If there is a problem with the timing belt, it will cause damage to the internal valves of the engine, and the car owner will have a greater expense.

Therefore, the timing belt must be replaced within the mileage specified by the manufacturer. Although the vehicle is idle and maintenance, the car is not driven for a long time, such as the engine oil will be oxidized, and the deteriorated engine oil will be cemented due to more precipitation, which will cause corrosion to the parts, and then start the car will form a certain resistance, or lead to poor engine acceleration. Therefore, it is recommended that car owners should still keep their cars "exercising" regularly.

If it is really idle for a long time, the vehicle should also be maintained in time to avoid causing "internal injury" to the car. （

It's time for secondary maintenance.

First, the engine part:

1) Start the engine and listen to whether there is any noise when the engine is running at idle, medium speed and high speed.

2) Check the cylinder pressure or vacuum, remove the carbon deposits in the combustion chamber and grind the valve if necessary, adjust the valve foot clearance, and check whether there is oil leakage in the oil seal and the rear bearing of the crankshaft.

3) Disassemble the carburetor and gasoline pump according to the situation, and test and adjust it on the test bench if necessary to make it meet the standard; Remove the air filter and change the oil, clean the gasoline filter, and check the pipes and fittings.

4) Check the bolts and nuts of fastening the cylinder head, intake and exhaust manifold and muffler, check the fixing of the engine, the connection and fastening of the flywheel housing and the cylinder block.

2. Clutch and transmission part:

1) Check the clutch efficiency and bottom cover bolts, adjust the free stroke of the springboard, and add grease to the springboard shaft.

2) Check the gear oil released from the transmission, clean the gearbox and gears, check the fastening of the worn gear and flywheel housing bolts of the gear, shaft and transmission mechanism, install the transmission cover, and fill the gear oil with the right number to the specified height.

3) Check the universal joint, change the direction of the ten ampere shaft according to the situation, check the looseness of the transmission shaft and telescopic sleeve, check the intermediate support frame and bearing, fill the grease, and tighten the trailer hook nut.

4) Check the working condition of the hand brake, the fastening of the machine connection, adjust the hand brake part, and fill the brake shoe pin with grease.

5) Disassemble the final reducer and differential according to the situation, check the meshing of the gears, adjust the tightness of the bearings, add or replace the gear oil, dredge the air vents, check whether there is oil leakage, and tighten the screws and nuts.

The 200,000-kilometer car needs to be overhauled. The following is an introduction to the major maintenance of the car: 1. Oil filter:

It is usually replaced every 8000km or 1 year. The oil filter is to provide clean fuel to the engine and filter out the moisture and impurities of gasoline. Clogged oil filters can hinder the flow of lubricating oil, resulting in poor lubrication and wear on the engine, and even tile burning.

2. Air filter: The engine should suck in a large amount of air during the working process, if the air is not filtered, the dust in it will accelerate the wear and slip of the piston group and cylinder. The function of the air filter element is to filter out dust and particles in the air to ensure that sufficient and clean air enters the cylinder.

3. Gasoline filter: The function of the gasoline filter element is to provide clean fuel for the engine and filter out the moisture and impurities of gasoline. During car maintenance, the operator checks the cleaning and maintenance, the positioning inspection of tires, and the inspection of various fastening parts.

If you just replace the three filters, it is about 500 yuan, which is the ** of the 4S store;

In general, the maintenance of cars is mostly based on kilometers traveled; Time is only the basis for auxiliary reference (for example, some private cars cannot reach 10,000 km a year, so time must be limited); General vehicle maintenance is mainly divided into two aspects:

1. Body cleaning: interior cleaning for 3-6 months; Especially at the turn of the season, in addition to the center console, the interior of the car should be taken into account; Including air-conditioning ducts, under seats, etc.; Outside the vehicle, the car should be washed after the rain, and the bird feces and insect corpses that fall on the car body should be cleaned up in time; Waxing once a month or so;

2. Vehicle maintenance; Don't say it's a vehicle, any mechanical equipment should be carefully maintained; Insiders know a truth: that is, "cultivation" is more important than "cultivation"; When maintenance is in place, not only safety is guaranteed; At the same time, it can also greatly extend the service life and service life of the vehicle; reduce costs; It plays a role in doing more with less. The following points should be paid attention to when it comes to vehicle maintenance:

1. Replace the three filters and oil;

2. Check whether the brake fluid, transmission oil, and power steering oil should be replaced;

3. Detect brake pads, tires, shock-absorbing suspension, etc.;

4. Check the spark plug, throttle and oil supply system;

5. Front and rear rotation positions, routine (lights, batteries, etc.) inspection.

Only by hard work can there be harvest; If you start the car right, the car will naturally be worthy of you; Usually spend a small amount of money, but then you can save a lot of money.

200,000 kilometers normally, the oil needs to be replaced, and the oil search stool grid; Check whether the brake fluid, transmission fluid, and power steering fluid should be replaced; Detection of brake pads, tires, shock-absorbing suspension, etc.; Check the spark plugs, throttle valves, oil supply system; Front and rear rotation, routine (lights, batteries, etc.) inspection. The following is the relevant introduction of car maintenance: 1. Appearance inspection:

Before leaving the car, check the condition of the doors, hood, trunk, and glass to check whether the body is damaged, whether the body is tilted, whether there is oil leakage, water leakage, etc. 2. Engine and various oils: check the fixed status of each part of the engine, and check whether there is oil leakage and water leakage on the joint surface of the engine.

Check the fastening of the adjustment belt, and check the fixing status of the pipes and wires of each part. Check for replenishment of oil, sloppy coolant, and electrolyte. 3. Tires:

Check tire wear and clean the trunk. Replace the tire when approaching the wheel crack leak tire wear mark. Check the tires for bulging, abnormal wear, aging cracks, hard injuries, etc.

4. Clean and lubricate: clean and lubricate the oil stain of the engine compartment cover, door and trunk hinge mechanism. The general service life of antifreeze is 2 years, when the time comes, the antifreeze should be replaced during maintenance and the cooling system should be thoroughly cleaned.

Due to the hygroscopic brake fluid of the braking system, the brake fluid is changed every two years.

How should a 25,000-kilometer car be maintained? You only need to do a routine maintenance, and you can do it again after a major maintenance of 50,000 kilometers.

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. Hyundai car maintenance mainly includes the maintenance scope of engine system (engine), transmission system, air conditioning system, cooling system, fuel system, power steering system, etc.

3. The purpose of car maintenance is to keep the car clean and tidy, the technical condition is normal, eliminate hidden dangers, prevent failures, slow down the deterioration process, and prolong the service life.

Common sense of use: 1. Common sense of antifreeze use.

Antifreeze is best used all year round, in addition to the function of antifreeze cooling, antifreeze also has the effect of cleaning, rust removal and anti-corrosion, reducing the corrosion of the water tank and protecting the engine. Pay attention to the color of antifreeze and do not mix it.

Second, the use of brake fluid common sense.

The function of the brake system is closely related to the brake fluid, and when checking to replace the hardware such as brake pads, brake discs, etc., don't forget to see if the brake fluid needs to be added and replaced.

3. Transmission oil.

In order to ensure that the car steers flexibly, it is necessary to check the transmission oil frequently, whether it is gear oil or automatic transmission oil, and pay attention to the type of oil, which is usually high.
