Does the 2011 Mazda 2 have a timing belt or chain?

The 2011 Mazda2 comes equipped with a timing chain for the 1.5 L 4Cylinder engine, rather than a timing belt. Over the years the Mazda2 has used a mix of belt and chain depending on the year and the engine size. After the year 2014 they did end up switching fully to the chain though. A big reason why they probably switched over is because it is easier to maintain than the belt. The timing chain should last for the life of the vehicle unlike the belt which needs to be replaced every so often. The reason why it is meant to last for the life of the vehicle is because it is on the inside of the engine and isn't exposed like the belt which is on the outside. There are some scenarios where it might fail but it is meant to last for however long the car lasts.
