Understanding the difference between these two components is crucial for maintenance and longevity of the vehicle.
Timing Chain vs. Timing Belt
Before diving into the specifics of the Lexus GX 460, it's important to understand the roles of timing chains and timing belts:
- Timing Chain: A timing chain is a metal chain that connects the crankshaft to the camshaft, ensuring that the engine's valves open and close at the correct times. Timing chains are generally more durable and can last the lifetime of the engine.
- Timing Belt: A timing belt is made of rubber and serves the same purpose as a timing chain. However, timing belts require periodic replacement, typically every 60,000 to 100,000 miles, as they can wear out over time.
