was the belt. Even though it only had 30k on it. The noise has not returned 1 month later.
Could have been the first time i installed it i didn’t get the tension right. Infact i know i didnt, because i didnt have a tension gauge (Cricket) at the time and so just did it randomly. So this i suppose led to premature belt wear and the noise. A simple $5 belt later and my wife is happy. Didn’t even bother buying the top of the line gates one this time 🙂 I believe the new one was acdelco.
