Contour Enthusiasts Group Archives Forums Modifications Zetec Maintenance reccomended timing belt change milage?

first off, hello to everyone.
I just bought a 95 Contour GL with the 2.0 and a 5 speed.
The car has 93K mi on it and I am wondering what is the milage to swap the timing belt.

I have seen 3 different answers. 80K,120K,and Life of the car

so would someone with a factory maintenance book please tell me the "official" scoop?

Thanks in advance!
