Many owners know the car needs regular, routine maintenance, such as replacing the filter, oil and other consumables, check the tire and brake system security etc.. However, in vehicle running process, many parts are constantly wear, routine maintenance, check the range is far not limited to oil, three filters, brake pads, spark plugs, a lot of places if you usually do not pay attention to check, maintenance, fault or what occurs when unexpected. Valve EGR, a few of the auto parts which are easily overlooked.

ignition coils

A lot of people know that spark plugs need to be replaced regularly, but the maintenance of other components of the ignition system is ignored, and the ignition coil is one of them. When the engine is running, the ignition coil is often tens of thousands of volts of high voltage pulse current, because of its long working in high temperature, multi dust, vibration environment, it is inevitable to occur aging or damaged.

brake disk

Brake disc and brake shoe is a pair of friction pairs, brake shoe wear, brake disc will also have a certain wear. This reason is very simple, a lot of people in the maintenance of the vehicle, but only pay attention to replace the shoe, ignoring the replacement brake disc. The consequences of excessive wear of the brake disc is very serious, valve EGR reminded the general, in the brake shoe after the replacement of 2~3 times, the brake disc should be replaced. Don't love the hundreds of dollars, it gives you a safe and secure, but priceless.

dynamo bearing

Now a lot of repair work was dubbed the "loading and unloading", meaning that only for a change, not maintenance. In fact, as long as some parts of the maintenance, the service life is greatly extended, the generator is one of them. Generally speaking, when the vehicle is traveling 60 thousand 8 million kilometers, should overhaul generators, in addition, the bearing water pump, power steering pump, air conditioning compressor should also regularly check.

Electrical connector

The car in addition to a handful of important electrical connectors with gold contacts, most of the rest of the joints using copper - zinc alloy, EGR ADI valve said in normal circumstances, its reliability is guaranteed, but if the car runs under high temperature and high humidity, bumpy environment, it is possible to produce these joints loose, corrosion, bad contact fault, and some electrical faults are caused by strange and eccentric. Therefore, in routine maintenance, should focus on checking the car on the computer, sensor, fuel injection nozzle and other parts of the joint.
