Does the 2014 Toyota Highlander utilize a timing belt or a timing chain for its engine mechanism?

In a 2014 Toyota Highlander, the timing chain is a crucial component within the engine that is lubricated by engine oil, enabling it to last a long time. Unlike timing belts, which are prone to drying out and cracking as they are located outside the engine. To prevent timing chain complications, it is important to maintain the engine properly by changing the oil at recommended intervals. It is also advisable to use high-quality engine oils and oil filters. Keeping the oil level correct will ensure proper lubrication of the timing chain, which is vital especially since many modern engines tend to consume oil. Typically, timing chains are designed to last the entire lifespan of the engine. However, issues may arise once the vehicle reaches high mileage, such as around 200,000 miles, and may require replacement at that point.
