Yes. It has a timing chain. Manufacturer recommends switching it out at 120K miles.
I thought it would depend on the engine in the car, I know the 2.0 has a belt.
Gates ( they manufacture timing belts etc ) lists a timing BELT for the 2.0 L - 4 cylinder engine in a 2007 Volkswagen GTI ( they also show it as an INTERFERENCE ENGINE )
Does a 2007 Nissan Sentra have a timing belt or timing chain?
