Focus Zetec Cam belt interval - Roly93
Does anyone know when the cam-belt should be changed on this car (1.6 Zetec SE engine).
Is it just on mileage or is it age as well ?

This car will have a "Black Top" Zetec engine fitted.

Ford recommendation is 10 years or 100,000 miles, whichever is reached first, though you may wish to have it changed sooner. This is particularly advisable if the car does mainly short journeys with a lot of stop-start.

The belt hardly ever fails on these engines. It's nearly always the tensioner or pulleys that fail first.

If getting the cam-belt changed make sure that a complete kit is fitted, which will include tensioner and pulleys.

Only consider having a Ford or Gates belt kit fitted (Gates manufacture the belts for Ford!)

Yeah, every 100,000 miles or 10 years, and as someone else said they aren't known for failing sooner. That said I HAVE seen a few on eBay going dirt cheap because the cambelt has snapped at 60k, 70k, etc. It does happen.

I risked taking my Fiesta Zetec up to 97k and 9 years before I sold it on the original cambelt.

If I remember correctly (99% sure) you are supposed to have the valve clearances checked/adjusted at 100k or 10 years, too. This will cost a bit extra.
