I spoke to the previous owner of the vehicle and said that he did a tune-up on the vehicle like changing all the belts and all. Now the squeaking can probably only comes from the tensioner for all or just one of the belts being loose or too tight, I guess.
What's your opinion?

Hi,

I agree. A loose belt can cause this issue. There are two belts on the vehicle. If you follow the water test (I think it was you that asked how to identify which belt was making noise), it should let us know which belt is the issue.

Keep in mind, there are other things that can cause the noise such as contamination (oil or coolant) getting on the belt, a belt-driven accessory with excessive resistance, and so on.

Try the water test and let me know what you find.
