Default NST Crank Pulley Problem

I am getting a really bad squeek now on cold starts after the car has been sitting for a few hours.

After a while it will stop, but it will continue once I let it sit for a few hours. I can't figure out where the noise is coming from, but Ive narrowed it down to the tensioner pulley, or the alternator. I haven't taken the wheel off just yet to see if its coming from the crank pulley, but I highly doubt it.

Anyone else have this problem?

loose belts perhaps causing the squeek?

I highly doubt its the belt because the xB2's have auto tensioners. I can't speak for the xb1s.

I know that the belt is no too loose or too tight. The tensioner should make up for it being too loose or too tight unless the belt is EXTREMELY too loose then it wouldn't make up for it.

However, I found out the issue. I remembered when I installed the belt, it was a 6 rib belt. Well the NST crank pulley is a 6 rib as well, BUT the other pulleys are 7 ribs on our cars. When I first installed the belt, it was aligned all the way to the right side of the pulley (closest to the motor) BUT when I put on the alternator pulley, it was aligned to the left (furthest from the motor). So I moved the belt on the alternator to the right side and it hasn't squeeked since.

Problem fixed.

EXACTLY! The belt must be aligned closest to the block/engine on all pulleys, including the alternator pulley.

Glad you found your solution
