Hello, I think your problem is the crankshaft pulley, they carry an integrated rubber band in the pulley that divides it into two, the problem is that this band is detached and causes the outer part of the pulley to rotate on the internal instead of doing it at the same time, causing a squeak as if it were the belt and that it is not removed for more than tense or loosen the tensioner.您可以非常容易诊断,随着发动机停止,您可以在皮带轮的两个部分中与粉笔或油漆一致,您可以启动发动机片刻,然后再次停止,如果标记仍然对齐,则皮带轮很好,如果它们不对,它就松散了,您必须更改它。
