You should have a diagram to the left of the hood latch. In the diagram, it should show the tension pulley that needs to relieved. Tools: long ratchet wrench and socket. It's fairly easy to do.
It can cost between $14 and $30 to replace a serpentine belt on a car. The price can raise to $40 or $60 if a person has it done at a car shop.
The cost to replace this part will range from $40-$80+. This depends on the cost of the part, the brand of the belt and the labor charges of the shop.
I changed mine for only 40 Dollars when I bought the belt at Napa Auto Parts.Just take it off and take it to Napa and they will find the one you need for your Cadillac.
I just replaced mine because the automatic tensioner pully locked up (which from what I've found online was actually recalled though since I got mine used I was never informed) & melted the pulley & belt. The tensioner was about $90 & belt was about $40. All in all it took about 2hrs to replace both parts & get it up & running again. Good Luck!
Need to know how to replace fan belt on a case 40 xt
lubricate your serpentine belt with some belt grease or some WD-40 and see if it doesn't stop.
First thing is to look at the bottom passenger side pulleys. These cars have a serpentine belt ( 1 belt for all pulles ). There is an Idler pulley that believe it or not bends when you try to loosen it off ... this tensioner will allow you to change the belt and alternator ... before you change the alternator get someone to look at it it could be just the Voltage Regulator 40 roughly to replace ( It is located on the back side of the Alternator ).
The easist thing to do is replace the tensioner. A new one will set you back around $40 and should take you well under an hour to change. Just release the belt and remove off the tensioner, undo the single bolt that holds the tensioner in place, remove, and replace. The hardest part is there isn't a lot of room to get your hand in there so you might have to remove the idler wheel to get more room, but again, this is only held on with one central bolt. Hope this helps.
If it has antifreeze on it you may have to replace it. I have shot some WD40 on MANY serp belts and had good luck. This will NOT hurt the belt regardless of what many 'experts' may say. Over the years I've had similar problems, both with conventional "v" belts and serpentine belts. In the "old days," rubbing "bar" soap on the belt[s] would do the job. Do NOT ATTEMPT to do this with the engine running. Be certain the engine is OFF, and I suggest, ALSO COOL to eleminate the potential for burns to hands or arms. I don't know exactly how it works, but I suspect that the soap acts as a lubricant. Also, I have had success by removing and reinstalling the serpentine belt, "reversing" it so that it travels in the opposite direction. As indicated in answer 1, WD-40 also has worked for me.j3h.
40 000 miles...........PS
cost me 260 for the alternator and the belt (220 and 40), and 190 for the labor.
2000 Honda has a timing belt its like a serpentine belt timing chains are used on some v 8 engines though most are the timing belts should be replaced every 40 thousand miles
