Re: a/c has a sound from it
Yes as long as you check with a shorter belt to make sure the shortened belt doesnt touch any other part.It would be easier to replace the clutch pack from the wreckers as it easy to remove from the compressor pump and replace.Pump doesnt have to come off engine.The biggest problem youll have if shortening the belt is that your power steer will likely be affected due to rotation speeds changing,anyway good luck and merry xmas

it will be pretty much hit and miss to get the right bely
you can get an estimate of the belt length by measuring the distance between where the existing belt contacts the power steering and crank pulley
make a note of that length (A)
now using a tape measure measure from the contact point on the crank pulley around the ac pulley to the contact point on the power steering pulley
make a note of that length (B)
now take A from B and reduce the original belt length by that amount
example -- if the original belt is 1485 mm long and the difference is 145 mm then you would be looking at a new belt length of 1340 mm
well that is the general idea
personally replacing the ac compressor is a far better idea , even if you do not re-gas the system or replacing the ac pulley bearing --cheaper still
Typically starting at the crank pulley the belt will go around the water pump then to the power steering pump then to the ac compressor then under the idler pulley then to the alternator then to the tensioner and then ending back at the crank pulley.
Some older models have the tensioner in a different location but the routing is almost identical.
Without the belt do all the pulleys turn easy. Power steering, water pump, alternator, and tensioner pulley. There is probably only one way the belt will stay on but make sure you have the smooth side to the smooth pulley and the grooved side to the grooved pulleys. See if any of the pulleys have and wiggle in them.
Belt goes over power steering pump,under idler on left,over AC compressor,over alternator,over fan (with back of belt ) over crank pulley then over water pump (back of belt) then back to p/s pump. Routing is counterclockwise.
That's easy, there are some pulleys with ridges to grip the underside of the belt, and some are smooth for the top side of the belt. I can only assume your belt broke and fell off so you couldn't see how it was on prior. But either way you have limited length, and the last place you would be routing the belt is the tensioner, which you should have located first, so you can have a wrench handy to fit it.
Here's what you have: Top left= alternator (small ridged) top right = power steering (large ridged) Bottom right = AC compressor (large ridged) Bottom middle = Crank Pulley (large ridged) In middle next to Power steering = Tensioner (small shiny smooth)
Remove the air cleaner housing (two bolts) Start on left top side and loop belt (clockwise) across the alternator to the power steering down to AC (also clockwise from right to left) then over to crank pulley (from bottom clockwise around to top of pulley) to tensioner (smooth, belt is backwards on it) which will go back up to the alternator.
At the top middle there should be a sensor protruding from the timing cover that the belt passes under as it connects between the alternator and the power steering. And you won't easily be able to fit anything besides a box-end wrench on the tensioner, so you may need some kind of extension on the wrench to get good torque on it without hurting yourself.
remove the belt to ac compressor.take your serpentine belt go around crank pulley goes around power steering pump goes around alternator and the tensioner on the far left. the water pump on the out side and the top idler pulley out side. the belt drives them from the out side. then you put your ac compressor belt back on.
hi there it sounds to me that the bearings are going bad on your ac/c compressor
you can bypass it by getting a smaller belt to get a size you can take a piece of string or rope and go around the remaining pulleys like alternator power steering and crank shaft then tie a know take it to napa and have them match as close as possible then install that belt this will solve your problem until you replace the compressor the other way is go to a salvage yard look for you make and model without a/c there will be most likely a pulley and bracket in the place of the a/c compressor take a picture of the set up and take the pulley off including the mount bolts and then remove th compressor on your car and install the pulley and you can use the same belt don
start at power steering down to ac compressor to crank...around crank to belt adjuster....over fan pulley to alternator up from alt and over both idler pulleys....a 17mm 12point wrench will fit on adjuster to move it
