Does the 2008 Lexus RX 350 have a timing belt or chain?

The 2008 Lexus RX350 is equipped with a timing chain and it's the year that they transitioned away from the timing belt in this model. This is good news for many people as the timing chain can mostly be ignored and doesn't require maintenance like the belts do. A chain is designed to last for as long as Your engine does under ideal conditions but like anything else it's still possible that they can break over time. You can do Your part in reducing the risk of that happening by changing Your oil regularly and making sure You don't run low on oil at any point. A lack of oil can cause the chain to dry up and it's more likely to break down. -
