How often should the cam belt be changed on a 2000 Ford Mondeo LX?

I want to say 60-90k miles, but to be certain contact your local Ford dealer and ask them the scheduled maintenance for it.

UK recommendations are

1.6 Ltr eng code L1L 100,000mls or 10 yrs

1.8 Ltr eng code RKF 100,000mls or 10 yrs

1.8 Diesel eng code RFN 70,000mls or 5yrs

2.0ltr eng code NGB 100,000mls or 10 yrs

2.5ltr eng code SEA chain driven

All Mondeo's manufactured after 2000

are fitted with timing chains

I hope this helps
