Just refering to a Zetec motor timing belt. I waited until 124k to change out the timing belt on my Contour and luckly it didn't break on me. It had about 6 inches of teeth missing. I will change the belt at about 90-100k miles personally on a Zetec motor and with the SVT Zetec motor, I would have at 70k miles if I wouldn't have sold it. Actually, on my wife's ZX3, its fixing to turn 100k miles, so its getting soon.Anaxagoras1986 said:What kind of car was this on btw?
