Re: I can't catch a break...squeaking coming from engine bay?

The intstall went easily and nothing went wrong from what I could see but when I turned on my car I heard a loud squeaking noise that sounded almost like belt slip coming from the engine bay. Because I thought it was belt slip I decided to reinstall the Tighed belt wrap kit in hopes it would cure it... no such luck. So I'm stuck with a beautiful beast that sounds like an old beater. Any ideas? It sounds like its coming from the alternator pulley or the alternator itself. What makes it weirder is when the car warms up after a 5-10 minute drive the noise goes away till it cools down a little. Any help would be really appreciated. Ohh and thanks to Tighed again for filling me in that the standard nut on the tensioner pulley can be used to detension the belt... worked like a charm.

The killer of bearings are rotational speed, load, lack of lubricant and dirt. Ignoring the last two items to get the same life from a bearing you can decrease the speed and increase the load within certain limits or increase the speed again within limits and decrease the load. Adding a belt wrap increases the load on all the bearings as the tensioner increases the belt tension. The tensioner should be operated in its stock position or in a less tensioned position if possible. Only positively lubricated bearings can counted on at the extreme limits of both speed and load and this is not feasible on these bearings. Belt wraps should have longer belts to increase pulley friction and not the load which is applied to all pulleys.
