Does my 2014 chevy malibu have a timing belt or chain?

Your 2014 Chevrolet Malibu has a timing chain, and typically, these will last well over 100k miles without any significant maintenance requirements, unlike a timing belt that needs to be frequently inspected and replaced. However, timing chains can and do go bad sometimes, and You'll hear a clattering or rattling noise from Your engine when they do. Often times, it's not the chain itself, but ancillary systems paired with it, such as the tensioner failing. If You can catch the issue early enough, You'll be able to replace those malfunctioning parts before the chain itself is compromised and needs replacing.
