Timing chains are designed to last the lifetime of the engine. It is timing belts that require changing at certain intervals.
I was looking at the Gates website ( they make timing belts etcetera ) and happened to choose the ( 2006 ) model year of the Ford Fusion , and they don't list a timing belt for the 2.3 liter four cylinder engine or the 3.0 liter V6 engine . As far as I know the four cylinder has ( 1 ) timing CHAIN and the V6 engine has ( 2 ) timing CHAINS ( 1 chain to each cylinder head )
The Ford Focus 2.0L has a timing chain.
