There are several possible reasons for this. The new belt may be the wrong size or have a different number of grooves cut into the belt. Some pulleys have more or less grooves which must match the number of grooves on any grooved pulley, even if only 1 pulley has the grooves.

Mounting the belt through different paths which makes slack in the belt.

Frozen or worn Belt tensioner which fails to put adequate tension on the belt. Idler pulley bearings can be worn out and new belt is now causing bearing to show up with noise.

When routing belt, make sure grooved part turns on grooved pulley and not the smooth backside of the belt.

There would be a tensioner pulley which you would move to release tension on the belt. The pulley is spring-loaded to keep the belt tight.

I believe there is another bolt

PROBABLY AN IDLER PULLEY, CAN BUY A NEW ASSEMBLY OR DRIVE OUT OLD BEARING & REPLACE THAT
