Ford cambelt & service intervals, by engine

Of the 5 Ford engines covered here, 1 runs a chain, 1 a conventional belt, and 2 a wet belt running inside the engine oil. The wet-belt engines are the ones to look at hardest: their published intervals have moved, and the failure they cause is an oil-starvation failure rather than a broken belt. A Ford with a chain and a Ford with a belt can sit in the same showroom in the same year, so the model name tells you nothing useful on its own. 1 of these carries no published interval here, because the figures in circulation don't reconcile and we won't pick one.

Questions people ask

Does a Ford have a cambelt or a timing chain?

Both, depending on the engine. Ford has sold belt-driven and chain-driven engines alongside each other, so the answer comes from the engine under the bonnet rather than the model name or the year. The table on this page lists each engine we cover and which it uses.

When should the cambelt be changed on a Ford?

It depends on the engine, and in some cases the published figure has been revised since the car was sold. Each engine in the table shows the current interval, its confidence tier and its sources. Where we show nothing, we haven't established a figure we would stand behind — ask a Ford dealer to quote the schedule against your VIN.

Which Ford engines have a wet belt?

The table marks them. A wet belt runs submerged in engine oil, degrades in it, and can block the oil pickup as it does — which is why these engines are sensitive to oil-change history in a way conventional belt engines are not, and why their intervals have been shortened.

Does a missing cambelt change show up in a Ford service history?

Only if it was done in a network that records it. A documented belt change is one of the most valuable single entries in any service history, because the alternative is paying for the job again or gambling on an engine. If the record is patchy, a franchised dealer can confirm what the network holds against the VIN.

Proving the work was actually done

An interval only helps if you can tell whether the job happened. How Ford records servicing, whether the owner app shows completed work, and what a dealer will release — all of that is on the Ford service records page.
