Hey guys, my twin throttle body XR has developed a bit of a problem. Over the winter, with the 4am starts, i noticed a bit of a belt squeel sound coming from under the bonnet. It was only on a cold start up, it would do about 4 or 5 sharp squeeks, the quickly go away. I noticed today though, that its doing it on warm start ups, every time, no matter what the engine temp is at. I got it home and pulled the belt off, its only 3 weeks old, so that wasn't the problem. I then gave all the pullys a spin, but they sounded fine. So then, with the belt off, and the thermo fans out, i gave it a quick start, ran it for 3 or 4 seconds and then shut it off. And guess what.... It still did it. So whats the deal?? Its not pullys, p/steer pump, alternator, idler or tension pulleys. But it sounds like a belt squeel or a dry bearing. I put in a pic, but i got no ideas.......

it might be the thrust bearing

Umm.. doesn't the thrust bearing only engage when in gear and clutch out?

Have also noticed that with the thermo fans out, belts off, like it was before, if i kick it over with out starting it, it makes the noise as it spools down. As in, i turn the key, it cranks over, i shut the key off, it doesnt start, but as it spools down it makes that damn noise..
