I have a 2012 Cadillac SRX and am about to replace alternator but I am having trouble getting serpentine belt off

SOURCE: Replacing front turn signal bulb on 2006 Cadillac SRX

wow i feel sorry for you because Cadillac designed this bulb to be a don't get to bulb but OK here's what you do take the bottom cover off or skid plastic panel under neath the front end theirs little plastic clips holding it on just get come dikes and don't cut them but just use it to help pull them out. after you get that off use a flash light and locate your light housing you should see two screws holding the house in i think those screws are 8mm i cant remember remove those two screws and be careful the metal from the bumper cuts you pull the light housing out and remove all the screws around the housing and open the housing up replace the bulb and make sure your contact to the bulbs clean and then reassemble the way you took apart. if you cant get it well then best bet is take it somewhere i know Cadillac charges an arm and a leg so you can go somewhere else.

SOURCE: replacing a serpentine belt

Don't have a chart, video, or diagram available at the moment. Can offer you generic advice.

1.Somewhere in the middle of that serpentine belt, that is wrapped around all those pulleys, is an Idler tensioner Pulley. All this pulley does, is put tension on that serpentine belt. Usually located somewhere in the middle.

The Idler tensioner Pulley will be on a bracket. It will be on the end of the bracket. The bracket usually has a 1/2 inch square hole in it. This is used for a tool, that resembles a 1/2 inch breaker bar.
-> I, use a 1/2 inch breaker bar.
The 1/2 inch breaker bar is inserted into this square hole, and the bracket is pulled to one side.
This pulls the tensioner pulley away from the serpentine belt, allowing the belt to have slack, and then the belt is slipped off of one of those pulleys. Release the pressure slowly, remove the tool. Then the serpentine belt is removed all the way.

(The Idler tensioner pulley bracket, can only be moved in one direction, to take pressure off of the serpentine belt. The direction opposite, of it putting pressure on the serpentine belt.

The spring used to put pressure is Very strong. This is also an area, where you can easily slip, cutting your knuckles, or fingers, or hand, on sharp objects. Use caution, you may want to wear a glove, or gloves!)

Then the new serpentine belt is wound around the pulleys in the correct pattern, the Idler Tensioner Pulley is once again pulled to the side, and the last of the serpentine belt is slid into place. Then you slowly release the tensioner pulley, and it puts pressure on the serpentine belt once more.

Make sure the serpentine belt is in the grooves of the pulleys, and is wound around in the correct pattern.

On the car hood inside, or on the radiator support, or perhaps on the inner fender well, or in the Owners Manual, it should show the correct pattern for installing the serpentine belt.

Ok, Alternators are a breeze on these things. There are two bolts that hold it on, and 2 sets of wires. If you haven't taken anything apart yet, and the belt is still on it, here's what to do. You will want one of those rubber or elastic bungee cords, about 2 and a half feet long(this makes it easy). Hook that bungee cord to your hood somewhere, so that it hangs down. Hook the other end on the serpentine belt right next to the alternator pulley. If you need to prop the hood up with a stick or something to keep it up, do so. Pull up on the belt, and watch the pulleys. The one that probably has a plastic pulley on it that moves up and down(this is the tensioner) is the one that you'll put a deep well socket in the middle of with a ratchet, and turn counterclockwise. This will make the belt go loose. Now you can work the belt off the alternator pulley, and once you get it off, the bungee cord will keep it in place, so you don't have to look at the diagram. Otherwise, if it comes off, there is a sticker just under the hood either on the fan shroud or the radiator support that has the belt diagram. Now, you can disconnect the battery, pull the rubber boot down off the nut and post on the back of the alternator, remove the nut and wire, and then unhook the wire from the side of the alternator. Now, you can remove the two bolts that hold the alternator on. You Will need to pry the alternator off at this point, as it fits really tightly in place. A socket extension or a large flat screwdriver works really well for this. Once you get it off, put the new one on exactly as you took the old one off. Note, you will have to release your tension on the tensioner at some point; i just ease it down, or if I can pull it off, wedge it somewhere where it won't loosen very far. Remember, on the tensioner, you're not trying to take the nut off. All you're doing is using it to move the tensioner arm. That's all there is to this job. Sometimes it can be stubborn with the prying part, especially getting it into place. Hope this is what you're after, and if you need more info, leave a comment for me.

Testimonial: "Great advice on the bungee cord!! Well written advide and easy for a novice to follow. Thanks"
