16万公里的93Corolla（我以前帖子提到的那车），TIMING BELT一定要换吗？谢谢。

You need ask the previous owner if he ever changed. If not, then一定要换.
If cannot find the previous owner, it'd better to change.

when you replace the timing belt, you shoud let the mechanic check the tensioner, water pump and crank seal at the same time, and replace them if necessary.

the following price comes from Canadian Tire as reference for you:

Timing belt: $48
Labour cost: $210 (2.8 hrs)
Water pump: $106 (brand new)
Tensioner85 (from Ford Dealer)
Seals: $35

there is no labour cost charged for Tensioner,water pump and seals if they replace them together with timing belt.

Much thanks for your precious information! Luckly the former owner of the car has told me the timing belt has been changed.
