In addition to replacing three filters、Oil and other consumables，Check the safety of tires and braking systems，Some parts are often ignored。These components have a vital effect on driving safety，or it can affect the braking of the car、fuel consumption，Some even affect driving safety。

* Electric plugs

In addition to a very small number of important electrical interpolations on the car, gold contacts are used，Most of the remaining joints use copper-zinc alloy，Under normal circumstances，Its reliability is guaranteed，But if the car is at high temperature for a long time、High Wet、Run in a bumpy environment，These joints may generateloose, rust, poor contact and other faults.Therefore, in routine maintenance, you should focus on checking the carComputer、Sensor、Joint of nozzles and other components，If there is a loose、The rusty phenomenon，You can use Vaseline to deal with，or change new plugs。

* ignition coil

When the engine is running，Tens of thousands of voltage pulse currents often on the ignition coil，Because it works at high temperature for a long time、Duchen、In the environment of vibration，If the use method seabet myis improper，Will cause damage to ignition coils。

Pay attention to the following points during use:

Prevent ignition coils from heating or moisture;

Do not turn on the ignition switch when the engine is not running;

Frequent inspection、Cleaning、Fascinating line joint，Avoid short -circuit or iron;

Control the performance of the engine to prevent excessive voltage;

Spark plugs must not "hang fire" for a long time;

The moisture on the ignition coil can only be wiped with cloth，Never bake with fire，Otherwise, it will damage the ignition coil。

* brake disk

If there are clear scratches，It is recommended to replace a new brake disk。brake disk and brake film is a pair of friction deputy，The brake film is worn，The brake disc will also have a certain wear。Most car owners think that brake pads are easier to wear than brake disc，No attention to the brake disc did not attach enough attention，In fact, the forces of the market and the film are mutually mutual，contact friction will be worn，And the surface of the brake disc is smoother than the brake pad，1Easy to be affected by the rough surface of the brake pad。

The brake pad itself is easy to damage，But while we check the replacement of the brake pads，Also pay attention to the status of the surface of the brake disk，If there is a clearer scratch，It is recommended to replace the new brake disk，to avoid unexpected consequences。Generally speaking，After 2 ~ 3 times in the brake film，The brake disk should also be replaced。

* ignition line

End of the ignition line connect to split appliances and spark plugs，It is the path passed to the engine electrical spark during driving，Due to the high frequency and the working environment are relatively harsh，Easy to appearaging, damageand other phenomena，Aging seabet loginof ignition lines will affect vehicle power and fuel consumption。It is recommended that the vehicle changes the ignition line every 20,000 kilometers.

* turning the lever

Steering tie rod pine is a serious safety hazard，So，During routine maintenance，Be sure to check this part carefully。The method is very simple: hold the tie rod，Shake hard，If not shake，It means that everything is normal，Otherwise，​​You should change the ball head or tie rod assembly。

* Suspension control arm glue sleeve

The vehicle will run off when the glue case is damaged、During a series of faults，Even if you do a four -wheel positioning, it will not help。If you carefully check the chassis，Plastic sleeve damage is easy

* shock absorber

Oil leakage is a prerequisite for damage to the shock absorber，Another，Driving bumps on the bad road significantly exacerbate or make the braking distance longer is also a sign of damage to the shock absorber。

* exhaust pipe

The exhaust pipe is one of the most easily damaged components in the bottom of the car，Don’t forget to take a look during maintenance。Especially the exhaust pipe with a three -way catalyst，Should check it carefully。

* Wiper maintenance

Some car owners attach great importance to the daily abnormal state of wiper tablets.，until it affects the effect of the wiper，Questions are usually serious。Except for daily use，If there is less water on the front glass，Empty wiper，Easy to increase the wear of wiper，Affecting its horizontal degree。A strong thing appears on the front glass，Drying feces of birds such as pigeons，Also avoid using a wiper directly。

During the use process，Seeing the wiper from the windshield that has a slender strip mark，It is difficult to see the outside world，This may be becauseWiral scrape with foreign bodies or edges is worn，Do not rush to replace，First clean the edge of the edge，If the symptoms are still eliminated, you need to replace it。
