SOURCE: on 98 intrigue water pump removal how do i clear the ps pully

Im not sure what engine you have since this information was not provided. But the Power Steering Pump pulley usually has some 'holes' on the pulley in which you can get a wrench through to loosen and remove the bolt.

To get the alternator out, I had to move that large electical fuse / relay box out of the way,and remove washer bottle and battery. then use a 3/8" drive ratchet to move the tensioner forward to get the belt off. I used a small mirrow to get a view of the back bolts on the alternator and removed them.[ I used meteric # 15 open end & closed end combo wench. Keep turning the back bolts until the alternator become loose.]

SOURCE: need to change alternator but dont know where

Ok, the easy way to find the belt tensioner is:
Find the two pulleys that are made out of plastic or nylon. Grab the belt and pull (or use a large screwdriver, or something like that for leverage). Watch to see which pulley moves side to side, not rotating; it'll be one of two smaller pulleys in the middle of everything. When you find this, then you can put a socket and ratchet on the bolt in the middle of the pulley, and turn to get it to loosen. It won't stay put, so you'll have to loosen, and slide the belt off say, the water pump pulley(also for the fan), then you can let the tension off. Hope this is what you were looking for.

SOURCE: remove alternator

There is two bolts behind the alternator,one short,one longer,then there is one that goes all the way threw the alternator,from the pulley side.You will have to remove the bolts to the body on the front two motor mount struts,and tilt the struts backward toward the engine.Then use a treaded rod and bend the end of the rod and use a L bracket with a hole in it to run threw the treaded bolt,and use the bent end to hook the eye on the strut mount on engine and pull the engine forward towards the front of the vehicle to gain access to remove the alternator,of course the power steering pump has to come of also and tensioner and plate behind the tensioner has to come off to be able to get the alternator out.If this was at all helpful,please rate,thank you.

Alternator pulley shears off. Alternator is about 1 year old. The last few times I started the car there was a hard screech noise (like metal clanging) coming from the area around the serpentine belt....

If the bolt was lose and caused the pulley to bend down the power behind the belt was too great and sheared the pulley. Check belt for damage and replace pulley.

Dont know how to loosen or tighten the belt im trying to put on my car. the belt is connecting the alternator to the waterpump

You need to loosen the bolts that attach the alternator to the engine. Just loosen then a turn or so, don't remove them. Then there should be a long 10 or 12mm bolt attached to a bracket being held by one of those bolts attaching the alternator. One direction loosens while the other tightens the belt. When it is where you want it, retighten the alternator bolts and test.

Assuming this is a XG 350, the process is lengthly.
1. Remove the RH radiator cooling fan (two 10mm bolts at the top & wiring harness connector to it).
2. Lift vehicle to remove the Right Front wheel (then remove 4 10mm bolts securing the plastic splash shield & remove it)
3. Loosen the 14mm nut on the alternator belt tensioner pully
4. Loosen the tension on the belt by rotating (counter-clockwise) the 14mm bolt at the bottom of the idler pully and remove the belt.
5. remove the pully & the idler pully (three 12 mm bolts)
6. Loosen the 14mm nuts at the top and bottom mounting points of the alternator.
7. Using a floor jack (or vehicle lift), support the engine using a jack-stand & 2x4 piece of wood under the oil pan.
8. This is tricky - lift the engine 'SLIGHTLY' to take pressure off the front engine mount - loosen the 17 mm nut on top of the mount itself and observe engine movement. If the engine moves upward 'slightly' remove the 17mm nut - if not, raise the engine slight more until you see the mounting bracket rise off the mount.
9. Remove the remaining 17mm nut (deep well socket), and two 17mm bolts and remove the engine mount bracket.
10. Here's another tricky step. Some 350's bottom Alternator bolt bores are 'SLOTTED'... some are NOT. You'll need to determine wether you'll need to REMOVE the lower bolt, or just loosen the mounting sleeve at the bottom bolt. If it's 'sleeved', I use an air hammer to loosen the sleeve. If it's not slotted, I remove the lower bolt (it's the only way to remove the alternator and pry it off).
11. At the top is an "L" bracket which uses two 12mm bolts to attach it to the engine (head). One of the two 12mm bolts is difficult to get to -- do your best to remove it because the battery cable to the alternator is in the way.
12. Disconnect the alternator wiring (battery cable & regulator harness connector)
13. Lift the engine as high as it will go & pry the alternator off its lower mounting.
14. manuver the alternator upward taking care not to damage the radiator.
15. Installation is in reverse order.
NOTE: If your XG's lower mounting point was slotted, your task is easy. If it isn't, your task now becomes more difficult as you must align the new alternator to facillitate re-insertion of the lower bolt.
PS If not slotted, I use a telliscoping magnet to help re-insert the lower bolt.

2003 cts. I need to replace alternator. can i do it myself and how much does the part cost?

I have actually done this on my 2003 CTS. The part was about $300 at Autozone. You have to disconect the battery, take off the belt (which can be done with a rachet to move the pully above the alternator pully to loosen the belt, remove the 2 long bolts keeping it in place, remove the sensor wire and the wire that goes to the battery at the back of the alternator. I had to use a crow bar to move the alternator to the side so I could remove it. Here's the hard part, trying to finegle the alternator out was difficult. You may want to remove the pan bolted to the bottom of the alternator (4-6 bolts I think) If I were to do it again I probably would have also removed the big plastic air intake part.

How do i replace an idler pulley on a 02 xg350l

the 02 and the 05 are identical. There are TWO idler pullys ... one for the power steering, and the other for the AC compressor & alternator -- WHICH ONE? In any event, you'lll need to remove the right front wheel and the splash guard (10mm bolts) to access either of the pullys. Use 14mm wrench (or ratchet & socket) to loosen the appropriate pully (Pwr Steering has 14mm nut & two 14mm bolts), The other pully has one 14mm nut & one 14mm bolt.
Go to and register( Vehicle by VIN). Afterward, you have access to shop manuals, service bulletins, wiring diagrams, etc. about your vehicle.

How do you adjust tension for drive belt

first you need to figure out if you have an automatic tensioner or an adjustable one. so look at the pullies which ones are not accesories (ie not an alternator pully, power steering.) some pullies will just be on there own not driving anything. is this pully connected to something like this O>o <--this end is the pully.
pully mounting bolt ^ ^arm with hole for rachet
or does it look like the pully is attached to a threaded pole.

the auto adjuster need a rachet to pull back on it (because it's spring loaded) while you install the new belt.

the other need the nut on the pully loosened and the threaded pole loosened will move the pully removing tension from the belt (opposite will tension the new belt).

tighten belt until you can only twist it in half.

How do i losen tension on 1990 acura legend alternator belt

If you lean into the engine compartment from the passenger side to look at the pully side of the alternator, you will find a bolt (10mm I think) sort of behind the alternator and to the back left. It is sticking straight up, and you can use a nut driver or ratchet to turn it counter clockwise to loosen tension and lower the alternator. But you have to loosen the locking bolt first. When you look at the pully side of the alternator (once the plastic shroud is removed to expose the belt and pully) you will see 2 large bolts (one on the bottom right and one on the bottom left) on the alternator that hold it in place. The one on the bottom left (on the same side as the tension adjusting bolt) is the locking bolt. You will see that there is a track for it to slide along as the alternator swings up and down. If you loosen this bolt, the alternator should be free to swing down on the left side when you adjust the adjusting bolt. However, it is common for the alternator to stick even after you have loosened the locking bolt and . When I adjusted mine, I had to remove the bolt on the bottom right because my alternator had been in there so long is was stuck in place. (The alternator is supposed to pivot on the right bolt, but sometimes it sticks.)
