At what mileage should the cam/serpentine belt be changed?
Is this the best time to go to underdrive pulleys?

My dad has always said 60,000 miles for pretty much any car. Alittle prevetative matienance can save you in the long run.

I looked in the manual and Ford says to replace the timing belt at 120K miles. Thats kinda nuts considering you normaly do it between 60-75K. But thats what the schedualed mantinence is for it. What sux about rubber timing belts is that they brake w/out warning, unlike a timing chain that will squeel when its worn out. If it goes befor that 120K your in for a world of hurt.

^^^why? [confused]...all that would happen is that the belt breaks...the car gets towed...u put a new one on...and u now know how long it takes before it breaks...the motor is non-interference so no valve train work or damaged pistons, etc...im not feeling the hurt [;)]

If the belt beaks,the car wont start....Ive owned other Fords (EXP) that after this happens and you try to re-start the engine,major engine damage occurred to the valve and pistons.Would this still happen to our Focus?
Whats non-interference?

Replace it before 80k.It's not that hard of a job.I just did one on a 2000 with 82k that was towed in.It did not break,but lost about 20 teeth and would not start.I know they say these are non-interference motors,BUt I have personally seen them bend valves if the belt snaps at the dragstrip.[mecry]

Well I have 122K miles on mine so I guess I should look into getting it changed. Same thing with the serpentine belt.
