Took off my serpentine belt to replace alternator. Went to put it back on and it is really loose. The belt path is right. It looks like thr tensioner is not in the rigt place

Double-check that the ribbed side is riding on pulleys with ribs and the smooth side is riding only on smooth pulleys. Suspect the spring-loaded tensioner is stuck. Usually you can pull them back with the ratchet or breaker bar. Once you do, there's a 50/50 chance it will move freely in the area it needs to keep the belt tight. If it doesn't maintain proper tension on the belt, replace the tensioner.
