Does a 2000 Ford Mustang 3.8 V6 have a timing belt or timing chain?

The vehicle has a timing chain that keeps the camshaft spinning correctly relative to the crankshaft. It also has a serpentine belt (what used to be known as fan belts) that operates the AC compressor, alternator, air pump, and water pump.

Some people still call serpentine belts a timing belt even though it has no effect on engine timing.

Many 4 cylinder engines use a timing belt in place of a chain. I think this is where the confusion starts.
