How Often Should a Turbocharger Be Replaced?

[StSamuel]

Turbochargers typically need replacement after approximately 250,000 kilometers of vehicle operation. However, turbochargers that have exceeded 100,000 kilometers often exhibit noticeably reduced engine performance compared to new vehicles, which may be caused by air leaks, unstable pressure, or blade damage. The full name of a turbocharger is exhaust gas turbocharger. This system compresses low-temperature, low-pressure gas into low-temperature, high-pressure gas, increasing the engine's air intake to achieve the goal of injecting more fuel and enhancing engine power. Although the turbocharger itself is a low-temperature component, its power source comes from the high-temperature, high-pressure exhaust gases of the engine, with exhaust temperatures reaching 900 to 1,000 degrees Celsius. Additionally, under full engine load, the turbocharger's rotational speed can reach 180,000 to 200,000 revolutions per minute. Consequently, the turbocharger operates in an extremely harsh environment, which directly impacts its lifespan.
