Belt squeak could be a drive belt tensioner, easy way to diagnose is spray some WD40 or similar on into the tensioner bearing to see if the noise disappears. Replace it if it does.

Pros: easy to diagnose

Cons: belt squeak

Steady belt run:

My dealership quoted me $710 for the drive belt tensioner which had a small leak. At around 38,000 miles. Probably a crappy design by Mazda if everyone’s starts to leak around that mileage.

Cons: crappy design, small leak

Mileage: 61155 km
