Does the Lexus RX 450h have a timing belt or chain?
The Lexus RX 450h is a popular luxury hybrid SUV known for its reliability, performance, and advanced engineering. One common question among owners and potential buyers is whether this vehicle uses a timing belt or a timing chain. Understanding this distinction is crucial for maintenance planning and long-term ownership costs.
Timing Belt vs. Timing Chain: What’s the Difference?
Before diving into the specifics of the Lexus RX 450h, it’s important to understand the difference between a timing belt and a timing chain:
- Timing Belt: Made of rubber and reinforced with materials like fiberglass, timing belts are quieter but require periodic replacement, typically every 60,000 to 100,000 miles.
- Timing Chain: Made of metal, timing chains are more durable and often last the lifetime of the engine. However, they can be noisier and may require tensioner adjustments over time.

Benefits of a Timing Chain in the Lexus RX 450h
There are several advantages to having a timing chain in your Lexus RX 450h:
- Longevity: Timing chains are built to last and typically do not require replacement unless there is a specific issue.
