a car has tens of thousands of parts. as an ordinary car owner, we can't and don't need to know the use of these parts. but in order to drive safely and prolong its service life, the car owners always pay attention to some common problems of vulnerable parts.
1, tires
replacement cycle: 50,000 to 80,000 km
to replace tires regularly, a set of tires can be used for a long time.
normally, the replacement cycle of a tire is 50,000 to 80,000 kilometers.
if there is a crack on the side of the tire, even if it does not reach the mileage.
for the sake of safety, it should also be replaced.
when the tread depth is less than 1.6 mm or the tread has reached the wear indication mark, it must be replaced.
2. wiper blade
replacement cycle: one year
for wiper blade replacement, it is best to replace once a year.
daily use of wiper blades, to avoid "dry scrape", so that it is easy to damage wiper blades.
serious damage will result in automobile glass.
it is better for owners to start wipers after spraying cleaner and more lubricating glass liquids.
the wiper blade should also be cleaned when washing the car at ordinary times.
3. brake pads
replacement cycle: 30,000 km
the inspection of brake system is particularly important, which directly affects the safety of life.
generally, the brake pads will wear out gradually with the increase of driving mileage.
if the thickness of the brake pad is less than 0.6 cm, it must be replaced.
under normal driving conditions, brake pads are replaced every 30,000 kilometers.
4. batteries
replacement cycle: 60,000 km
batteries are usually checked and replaced in about 2 years.
usually, when the vehicle is out of fire, the owner of the vehicle should use the electrical equipment as little as possible.
prevent the battery from losing power.
5. engine timing belt
replacement cycle: 60,000 km
the engine timing belt should be inspected or replaced in 2 years or 60,000 kilometers.
however, if the vehicle is fitted with a timing chain,
it does not need to be replaced under the restriction of "two years or 60,000 kilometers".
6. oil filter
replacement cycle: 5000 km
in order to ensure the cleanliness of the oil circuit, the engine is equipped with an organic oil filter in the lubrication system.
in order to prevent the impurities from mixing into the oil to cause oxidation, resulting in gelatin and sludge blocking the oil pipeline.
oil filters should travel 5000 km and be replaced with oil at the same time.
7. air filter
replacement cycle: 10,000 km
the main function of the air filter is to block the dust and particles inhaled by the engine during the intake process.
if the filter is not cleaned and replaced for a long time, dust and foreign matter can not be excluded.
if dust is inhaled in the engine, abnormal wear and tear of the cylinder wall will occur.
therefore, air filtration is best cleaned every 5,000 kilometers.
use air pump to blow clean, do not use liquid to wash.
air filters need to be replaced every 10,000 kilometers.
8. gasoline filter
replacement cycle: 10,000 km
the quality of gasoline is constantly improving, but some impurities and water will inevitably be mixed in.
therefore, the gasoline entering the gasoline pump must be filtered.
in order to ensure smooth oil passage and normal operation of the engine.
because the gasoline filter is a one-time use,
replacement is required every 10,000 kilometres.
9. air conditioning filters
replacement cycle: 10,000 km inspection
the working principle of air conditioning filter is similar to that of air filter.
to ensure that the car air conditioning can be opened at the same time breathe fresh air.
air conditioning filters should also be replaced regularly.
when using air conditioning, there is odor or a lot of dust blown out of the outlet, it is necessary to clean, maintain and replace it.
10. spark plug
replacement cycle: 30,000 km
spark plug directly affects the acceleration performance and fuel consumption performance of the engine.
if the engine is not maintained for a long time or even replaced on time, it will lead to serious carbon deposit and cylinder malfunction.
spark plugs need to be replaced once for 30,000 kilometers.
when choosing spark plug, first determine the type and heat level of the car.
when you feel that the engine is not powered enough when driving, you should check and maintain it once.
11. shock absorber
replacement cycle: 100,000 km
oil spill is a precursor of shock absorber damage.
in addition, the obvious increase of bump on bad road or the longer braking distance are also signs of shock absorber damage.
12. suspension control arm rubber sleeve
replacement cycle: 3 years
after the rubber sleeve is damaged, a series of faults such as deviation and swing will occur.
even four-wheel positioning is not helpful.
if the chassis is examined carefully, the damage of the rubber sleeve can be easily found.
13. steering tie rod
replacement cycle: 70,000 km
relaxation of steering tie rod is a serious potential safety hazard.
therefore, in routine maintenance, we must carefully check this part.
it's very simple: hold the pull rod and shake it vigorously.
if there is no shaking, it means that everything is normal.
otherwise, the ball head or tie rod assembly should be replaced.
14. exhaust pipes
replacement cycle: 70,000 km
the exhaust pipe is one of the most vulnerable parts of the car bottom.
don't forget to take a look during the overhaul.
especially the exhaust pipe with ternary catalytic converter should be examined carefully.
15. dust-proof sleeve
replacement cycle: 80,000 km
it is mostly used in steering mechanism and shock absorption system.
these rubber products will age and rupture over time, leading to oil leakage.
make steering astringent and sink, shock absorption failure.
pay more attention to check at ordinary times, once damaged, replace immediately.
16. ball head
replacement cycle: 80,000 km
inspection of steering rod ball joint and dust-proof sleeve for 80,000 km.
upper and lower control arm ball joint and dust jacket 80,000 km inspection.
change if necessary.
the steering ball head of the vehicle is similar to the limb joints of the human body.
often in a rotating state, need to get good lubrication.
because it is wrapped in the ball cage, if the grease deteriorates or is defective, the ball head in the ball cage will be loose.
be careful:
