Car maintenance is increasingly valued by people, and many car owners like to clean or lubricate their cars themselves in daily maintenance. However, there are always some maintenance parts in each car that we cannot reach or cannot imagine. Although these parts are difficult to reach, they play a crucial role in driving safety.

Ignition wire: to be replaced after 20000 kilometers

For the maintenance of spark plugs, I believe many car owners will pay attention to it. However, compared to this, only a few car owners may also value the position of the ignition line in the ignition system. Most car owners only realize that the problem is caused by the ignition line when their car has insufficient ignition energy, high fuel consumption, low power, or even misfires. Due to the harsh location and working environment of the ignition line, there is a higher probability of aging and damage. For engines equipped with a three-way catalytic system, insufficient ignition energy and low power can lead to serious consequences. Therefore, experts point out that it is best to replace the ignition wire every 20000 kilometers of driving.

Brake disc: excessive wear without realizing it

Compared to brake shoes, brake discs are less frequently mentioned by car owners in their daily maintenance routines. Actually, both are important. Most car owners keep staring at when to replace the brake pads, but do not pay attention to the deteriorating of the brake discs. Over time, it will directly affect braking safety. Especially when the brake pads are replaced two to three times, they should be replaced. After all, if the brake disc is worn too severely, its thickness will become very thin, which can affect normal driving at any time.

Generator bearings: 60000 kilometers need maintenance

Some people complain that 4S stores often rely on replacement and repair, but it actually depends on the specific fault situation. For example, as long as the generator is maintained according to regulations, its service life can be greatly extended. Generally speaking, after the vehicle has traveled 60000 to 80000 kilometers, the generator should be inspected and serviced. Similarly, the bearings of water pumps, power steering pumps, and air conditioning compressors should also be regularly inspected.

Wiper maintenance: regular cleaning to extend lifespan

Some car owners feel that there are not many opportunities to drive on rainy days, and the use of wipers is relatively rare. Therefore, they do not attach great importance to some abnormal states of wiper blades in daily life. Until there is an impact on the wiper effect, the problem is usually very serious. Except for daily use, if there is less water accumulation on the front windshield and the wipers are wiped empty, it is easy to aggravate the wear and tear of the wipers and affect their levelness. When solid objects such as dry droppings from birds like pigeons appear on the front windshield, it is also important to avoid using a windshield wiper directly. Due to the fact that the material of wiper blades is mainly rubber, they will age and harden over time. Car owners can purchase a rubber maintenance agent from a car supply store and spray it on the rubber parts of the wiper blades every month to maintain the rubber strip, which can extend its service life by at least 30-50%. In addition, when it is found that the wiper blade is not wiping thoroughly, a wiper blade repairer can also be purchased to repair the irregularly worn parts by rubbing the rubber part of the wiper blade.

If, during use, the windshield shows elongated streaks on the wiper blade, making it difficult to see the outside world, it may be due to foreign objects or worn edges. The solution is to first clean the edges. If the symptoms still persist, it needs to be replaced.
