Does the Lexus is300h have a timing belt or chain?
The Lexus IS300h, a hybrid version of the popular Lexus IS sedan, uses a timing chain rather than a timing belt. This means the engine's camshafts are driven by a metal chain rather than a rubber belt, which can provide improved reliability and longevity over the life of the vehicle.
Timing Belt vs. Timing Chain
Timing belts and timing chains both serve the same essential function in an internal combustion engine - they synchronize the opening and closing of the engine's valves with the movement of the pistons. However, there are some key differences between the two:
- Timing Belts: These are made of reinforced rubber and require periodic replacement, typically every 60,000 to 90,000 miles. If a timing belt breaks, it can cause significant engine damage.
- Timing Chains: These are made of metal links and are designed to last the lifetime of the engine. Timing chains are more durable and reliable than belts, but they can be more expensive to replace if they do fail.
By using a timing chain, the Lexus IS300h avoids the need for regular timing belt replacement, which can be a costly service. This helps to reduce the overall maintenance costs of the vehicle over time.
Lexus IS300h Engine Specifications
The Lexus IS300h is powered by a 2.5-liter, four-cylinder Atkinson-cycle gasoline engine paired with an electric motor. This hybrid powertrain produces a combined 220 horsepower and is mated to a continuously variable transmission (CVT).
The use of a timing chain in the IS300h's engine is a testament to Lexus' commitment to reliability and longevity. By opting for a more durable and long-lasting component, Lexus has helped to ensure that the IS300h can provide years of trouble-free service to its owners.
