Sounds as if you have a pulley/accessory that is out of alignment-most likely either ac or alternator- it takes very little to make it noisy.either cleaning mount for out of alignment accessory or washers to move forward can cure it sometimes

  1. Disconnect the negative battery terminal.
  2. Remove the splash guard on the right side of the vehicle.
  3. Loosen the alternator belt idler pulley.
  4. Slip the drive belt off the alternator pulley.
  5. Remove the four air conditioning compressor mounting bolts.
  6. Remove the radiator fan and fan shroud.
  7. Move the air conditioning compressor forward.
  8. Disconnect the alternator harness connector.
  9. Remove the alternator mounting bolts, and lower the alternator from the vehicle.
To install:
  1. Hold the alternator in place and install the mounting bolts.
  2. Plug in the alternator harness connector.
  3. Move the air conditioning compressor back into location.
  4. Install the radiator cooling fan and shroud.
  5. Install the air conditioning compressor mounting bolts.
  6. Place the drive belt on the alternator pulley.
  7. Tighten the drive belt to the proper tension with the idler pulley.
  8. Install the splash guard.
  9. Connect the negative battery terminal.
Proper belt tension is important. A belt that is too tight may cause alternator bearing failure; one that is too loose will cause a gradual battery discharge and/or belt slippage, resulting in belt breakage from overheating.

BMW 318i M46 belt tensioning




adjust ur belt by following steps
now that you know where the components are these components are driven by a belt. So when you turn your AC on there’s a belt that’s driving the AC compressor, when you turn the stirring wheel and you have that nice that easy feel of turning the stirring wheel when you’re parallel parking your car that’s the power stirring pump doing its job. Your alternator is keeping the battery charged, the lights on and the engine running. So I want to show you where the belts are, what they look like, how to adjust them and how to tell a bad belt from a good belt. As you can see these are your drive belts, this is the AC drive belt it drives the AC compressor, this is the alternator drive belt it drives the alternator, if you look down here you can see this is where the adjustment is on that AC compressor belt, if you look right here this is the top adjusting bolt for adjusting the alternator either up or down to tighten or loosen the belt. There’s a bolt down here that locks the alternator in place and this bolt is the pivot bolt for the alternator. So if you’re going to let’s say remove your alternator belt you’d have to remove these covers, loosen this bolt, loosen this bolt that’s underneath this cover and adjust this bolt to either lower the alternator or raise the alternator, if you’re belt was too loose you’ll pull up on the alternator, if the belt was too tight you’ll

Reset timingbelt on 1999 plymouth breeze sohc 2.0


When you break a timing belt, you get a kit with a new
water pump,pulley's,tensioners & belt

Also you get an instruction manual to follow for
the timing of the cams & such

If you only bought a belt, you should also have instructions

Nothing-- then you go to the internet & find a picture & also
can watch You Tube Video

If the belt broke-- what about bent valves,BEFORE,before
you address the belt replacement

Good time to do a cylinder leak down test

How do I adjust alternator belt?


Check to see if there is a tensioner pully that adjust the belt tightness. The tension pulley a small pulley will have two bolts on it one of them loosens and tightens the belt around the alternator and compressor USUALLY.

How to replace the power steering belt on a 4g13



ADJUSTMENT

Excessive belt tension will cause damage to the alternator and water pump pulley bearings, while, on the other hand, loose belt tension will produce slip and premature wear on the belt. Therefore, be sure to adjust the belt tension to the proper level.
To adjust the tension on a drive belt, loosen the adjusting bolt or fixing bolt locknut on the alternator, alternator bracket or tension pulley. Then move the alternator or turn the adjusting bolt to adjust belt tension. Once the desired value is reached, secure the bolt or locknut and recheck tension.

How do I replace the serpentine belt on a 1999 Kia Sephia?


1.8L Engine
  1. Using a belt tension gauge, measure the drive belt tension and compare with the following specifications:
    1. Alternator belt (new): 86-103 lbs. (383-461 N)
    2. Alternator belt (used): 68-86 lbs. (304-383 N)
    3. A/C compressor and power steering pump belt (new): 110-132 lbs (491-589 N)
    4. A/C compressor and power steering pump belt (used): 95-110 lbs. (422-491 N)

      zjlimited_1999.jpg
      Fig. Using a tension gauge to measure the alternator belt tension - 1.8L engines (click HERE for zoom)


  2. Using the deflection method, apply moderate pressure (about 22 lbs) halfway between the pulleys, and compare with the following specifications.
    1. Alternator belt (new): 0.31-0.35 in. (8-9mm)
    2. Alternator belt (used): 0.35-0.39 in. (9-10mm)
    3. A/C compressor and power steering pump belt (new): 0.31-0.35 in. (8-9mm)
    4. A/C compressor and power steering pump belt (used): 0.35-0.39 in. (9-10mm)
  3. If the specifications fall outside the ranges given, adjust the belt as follows:
    1. Loosen the alternator mounting bolt and adjusting bolt.
    2. Adjust the alternator to get the specified belt deflection.
    3. Tighten the bolts, then recheck the tension.

Squelling noise from aternator or belt tensioner


Good Evening, I would hope it is the belt or the alternator first because the belt tensioner is a bear to replace. I would recommend taking a better look at your belts first 80% of squeaking and squealing are from dirty, and old belts. And while you are changing it out you can spin each pulley by hand and see if there is one specifically making noise and go from there. Hope this helps.

High pitched howling and screeching (yes two different noises). The howling appears to happen when the air conditioning compressor pulley engages. The screeching, my guess would be from the belt. Any...


When the AC compressor kicks on, an electrical load is placed on the alternator and the drive belt that turns the alternator pulley, if not tight enough, can cause the belt to squeal. Replacing the belt should help with that noise if the belt is stretched from wear. The screeching noise can be from a bad idler pulley, a bad belt tensioner pulley or a bad alternator pulley or a failing clutch on a very old ac compressor and rarely a water pump pulley. To check pulleys remove the drive belt and turn them individually to see if they can be tilted up down or sideways with play in the "bearing" of the pulley. Also, you may wish to visually inspect the clutch on the ac and look for melted black rubber around the bolts that secure the clutch to the compressor (stinks,smokes and melts these rubber areas if ac compressor clutch fails).
