老Rx300到10万麦了，到自己常用的师傅那里，问换timing belt的事，师傅说这是大活
，包括water pump等一堆东西要换，约5小时labor, 估价在700上下。

不过师傅又说，timing belt其实非常结实，很少见belt断掉的，出问题的倒是那些控
制belt的转轴居多。不过这些转轴在出问题前，会有迹象可循。至于，water pump吗
？ 更是耐用，正常维护下，可跑20万麦。

他认为最佳选择是再开两万麦，然后换新车。不过那是他的意见，我自己决定，要换，
随时找他。


Update:
下面这话是个学车的人说的，看来和师傅的经验一致：
Therefore my educated guess for a Tundra (with 90K recommended replacement
interval for the timing belt) is about 5 to 10% fail before 90K miles,
making this a relatively rare covered under warranty repair. Between 90K and
120K miles about another 10% fail. After 120K miles the failure rate will
get much higher. By 200K miles about 90% fail.
