Is the belt not fitting properly because of it is too long or too short or is something getting in the way? It must be routed in the proper order. I believe that most cadillacs require the belt to be routed leaving the alternator pulley for last. A long 3/8" drive breaker bar should fit in the center of the tensioner. When you have everything lined up, pry the breaker bar slowly while keeping tension on the belt by pulling the belt onto the alternator pulley. Once it seats, slowly add tension back to the belt stopping every few inches to check the alignment. I hope that is helpful but I have not worked on a caddy in a few years.

So i took the serpentine belt off my 98 cadillac deville well when i put the new one on its too loose iv'e followed all diagrams what could be causing this

Compare your new belt to the old one. A millimeter or two isn't bad but if there's a noticeable difference, it's probably the wrong belt. Also, make sure your tensioner returns to the full tension side by itself. If it gets stuck or you hear grinding as you release the tension on the tool, you may have a bad tensioner and/or tensioner spring.

Does the 98 cadillac deville have a timing belt or chain

My book shows 3.0 ltr 1997-01 "V" engine with a timing belt recommended change at 100.000 miles or 60.000 miles under adverse conditions. It shows 3 idler pulleys that should be changed as well and all the cam and crank seals should be replaced as well because oil is the main killer of timing belts.. While you may consider the extra cost to be a burden you will not think so when you get 100.000miles trouble free in the timing belt area . Do not replace any of the items and you run the risk of all that work again in say 30.000 miles
