Question:
three years I opened the car 60,000 kilometers, and the performance has been very good, a few days ago to do maintenance, for a lot of things, friends said that some things do not need to change, such as pumps Is this you?

Answer:
6 million km of car maintenance to be comprehensive and needs to be replaced timing belt, tensioner pulley, water pump three-piece suit for the timing, drive-for-oil filter, antifreeze, is the importance of not more than when the belt that the belt once damaged, the engine completely finished. Timing belt tensioner pulley is the belt tensioner, tensioner pulley bearing bad, round hair belt Shibuya will be damaged. Pump is driven by timing belt, if the pump leak (antifreeze), antifreeze foam belt will be worse. Therefore, I advocate for three together, so as not to open another 20,000 kilometers belt, tensioner pulley is not a bad water pump is leaking, and will have to change (may have to change a belt). At the same time can be changed for antifreeze water pump, water pump for fast, if only to add some antifreeze, but if you use antifreeze with 4S different shops will not be able to add in the 4S shop.

Answer:
if tanks only, so long as there is no need for non-leakage, and may be changed only antifreeze and water, the premise is already too old antifreeze and water solution of the rust, etc.2006-01-03
问题:
我的车三年开了6万公里了,性能一直都很好,前几天去做保养,换了好多东西,朋友说有些东西是xx不需要换的,比如水泵,是这样吗?

回答:
6万公里对车需全面保养,需要更换正时皮带、涨紧轮、水泵为正时三件套，换机油机滤、防冻液,正时皮带的重要性不多说，一旦皮带损坏，发动机就彻底完蛋了。正时皮带涨紧轮是涨紧皮带的，涨紧轮轴承坏了，轮发涩就会损坏皮带。水泵是靠正时皮带带动的，如果水泵漏水（防冻液），防冻液会将皮带泡糟。因此我主张三件一起换，以免换了皮带开了两万公里，不是涨紧轮坏了就是水泵漏了，还得换（也可能还得换皮带）。换水泵同时可以换防冻液，如果水泵换的快只需补充一些防冻液，但是如果你使用的防冻液与4S店的不一样就不能在4S店补充.

回答:
如果只是水箱的话，只要不漏是不用换的，可能只需要换防冻液和水，前提是防冻液已经太旧了，水液锈了等等2006-01-03
