I'm getting the cold start noise that might be belt-related. This thread dates back to 2005, but now there might be some history and a TSB maybe? Anybody got some more recent info?

Re: Early H3 Noise
I'm getting the noise only at first cold start in the morning when outside temp is below 50F. Sound/pitch changes when I turn the wheel. I checked my ps fluid level and it's okay. Any TSB on this, I guess it's a belt issue?

Re: Early H3 Noise
Still making that noise almost every morning during cold starts. I better have the dealer fix it during next oil change visit.

Re: Early H3 Noise
It's getting louder now that early morning temp is about 50 degrees. And cranking the wheel (power steering) increases the noise. After 15 seconds or so, sound goes away.

But I was wondering if there's a TSB that I should refer to when I take it in for an oil change, etc.

Re: Early H3 Noise
Maybe there should be a FAQ TSB thread
