一些初駕車或初學濟南奔馳汽車維修的人員，可能會認為所有零配件都需要清洗，其實這種認識是片面的。對于發動機的紙質空氣濾芯，在清除其上的塵土時，就不能用任何油類清洗，只需用手輕輕拍擊或高壓空氣由濾芯內向外吹通即可;對于皮質零部件，也不宜用油類清洗，只需用干凈的抹布擦干凈即可。

Some people who are new to driving or learning to repair Jinan Benz cars may think that all parts and components need to be cleaned. In fact, this understanding is one-sided. For the paper air filter element of the engine, when removing the dust on it, you can't use any oil to clean it, just tap it with your hand or blow high-pressure air from the inside to the outside of the filter element; For leather parts, it is not suitable to clean them with oil, just wipe them with clean rags.

輪胎外胎如果長期堆壓存放且不及時翻動，就會因擠壓而發生變形，影響使用壽命;空氣濾清器、燃油濾清器的紙質濾芯，如發生擠壓，會產生較大的變形而不能可靠的起到濾清作用;橡膠油封、三角膠帶、油管等也不能擠壓，否則同樣會發生變形，影響正常使用。

If the outer tire of the tire is piled up and stored for a long time and does not turn over in time, it will be deformed due to extrusion, affecting its service life; If the paper filter element of air filter and fuel filter is squeezed, it will produce large deformation and cannot reliably filter; Rubber oil seal, triangular tape, oil pipe, etc. shall not be squeezed, otherwise it will also deform and affect normal use.

輪胎、三角膠帶、缸套阻水圈、橡膠油封等橡膠制品，如果靠近火源，將容易老化變質或損壞，另一方面還可能引起火災事故。尤其是一些柴油汽車，冬季嚴寒難以啟動，一些駕駛員常用噴燈加熱，一定要防止燒壞線路、油路等。

Rubber products such as tires, triangular tape, cylinder liner water stop, rubber oil seals, etc., which are close to the fire source, will easily age, deteriorate or be damaged, and on the other hand, may cause fire accidents. Especially for some diesel vehicles, it is difficult to start in the cold winter. Some drivers often use blowtorch to heat, so they must prevent burning the lines and oil lines.

有些零件本應一次性使用，個別駕駛員或修理工卻為了節約或因不了解“禁忌”而重復使用，這樣易導致事故的發生。一般來說，發動機連桿螺栓、螺母、進口柴油機噴油器固定螺栓、缸套阻水圈、密封銅墊、液壓系統的各類油封、密封圈以及重要部位的銷片、開口銷等零件拆卸后，須更換新品。

Some parts should be used once, but some drivers or repairmen reuse them in order to save or do not understand the "taboo", which may lead to accidents. Generally speaking, the engine connecting rod bolts, nuts, fixing bolts of imported diesel engine fuel injectors, cylinder liner water stop rings, sealing copper gaskets, various oil seals and sealing rings of the hydraulic system, as well as the pins and cotter pins in important parts, must be replaced with new ones after disassembly.

對于發動機汽缸墊，檢修時雖然沒有發現損壞，好也更換新品，因為舊品彈性差、密封不良、易燒蝕損壞，使用不長時間還需更換，費時費力，因此如有新品以盡量更換為好。更多相關汽車內容就來我們網站http://www.junwumy.com咨詢吧！

For the engine cylinder gasket, although no damage is found during maintenance, it is also good to replace the new one, because the old one has poor elasticity, poor sealing, and is easy to be damaged by ablation, and needs to be replaced after a short time of use, which is time-consuming and laborious. Therefore, if there is a new one, it is better to replace it as much as possible. Come to our website for more relevant auto content http://www.junwumy.com Ask!
