Does the GX 460 have a timing chain?
Yes, the Lexus GX 460 has a timing chain, not a timing belt. The GX 460 is powered by a 4.6-liter V8 engine that utilizes a timing chain system to synchronize the opening and closing of the engine's valves.
Timing Chain vs. Timing Belt
The main difference between a timing chain and a timing belt is their construction and longevity. A timing chain is made of metal links and is designed to last the lifetime of the engine, typically 200,000 miles or more. In contrast, a timing belt is made of reinforced rubber and needs to be replaced periodically, usually every 60,000 to 90,000 miles, as part of regular maintenance.
Timing chains are generally more durable and reliable than timing belts, but they can also be more expensive to replace if they do fail. Timing belt replacement is a relatively straightforward and affordable service, while timing chain replacement often requires more extensive engine disassembly, making it a more complex and costly repair.
