Does the 2009 Lexus RX 350 utilize a timing belt or timing chain for its engine mechanisms?

Question

Accepted Answer

The 2009 Lexus RX350, along with all other RX350 models, is equipped with a timing chain instead of a timing belt. Luxury vehicles like this commonly feature chains, which are made of durable steel and intended to last the lifetime of the vehicle. While chains may raise the initial cost, they are more reliable compared to belts which are typically made of cheaper rubber. The chain's lubrication and proper function depend on engine oil, so maintaining adequate oil levels and pressure is crucial to prevent the chain from failing.
