Belt squeal or pulleys?
I have '07 model with 30K miles. I've had it since 20K miles and the belt (as I thought) squealed since I bought it. It does only when the engine is hot. Cold morning start - quiet, no noise besides my single-mass-flywheel-clutch chatter. Drive 10min and squealing starts at low RPM. After a spirited drive, I can hear the noise at as high as 2000RPM. Past that it stops.
I bought one of the ubiquitous Gates belts (Micro-V AT), and the noise stopped after replacement.
Well, the solution was short-lived once the noise started peaking occasionally. Until it, basically, sounded like the old belt did (after about 3 weeks).
Now, I can order the OEM belt ($50
) and try that. But I wanted to see, if there are known issues with either the automatic tensioner or idler pulleys. What throws me off is the fact that there is no squeal when cold. All info I find on noisy belts refers to cold starts
