问：看来我的时正张力需要更换。它想确认

The noise can be isolated to the serpentine belt circuit (versus other sources) by just disconnecting the drive belt and BRIEFLY running the engine. If the noise disappears, then the issue is obviously a rotating element in the circuit and/or the tensioner (could be more than one source of noise, too). To isolate the issue, and have the tensioner replaced, if necessary, the service to request is驱动皮带张紧器检查/更换. If you request that service, the responding certified mechanic will get this taken care of for you promptly.
