It doesnt have to be over heating if the water pump bearings are bad. I take wd-40 and spray one pulley at a time on the back side if possible to isolate the bad pully bearings. Start with your ac compressor first because next to the idler the ac pulley sqeals alot.

SOURCE: engine noise

If it gets worse when turning the wheel at a stop, then it's the power steering pump. Could be the power steering fluid also. Check your belts for wear or damage. The idle pulley will make a constant noise, sometimes whining sometime screeching. To check idler pulley it is best to remove belts.

oNE BOLT MISSING IS A PROBLEM IN ITSELF. And yes if you have a swepentine belt you must have a tebnsioner,. If it's a V belt then no the missing bolt is probably your adjustment point. Good luck

The belts continue to make a loud screeching noises when i drive over 55. Sometimes when the car is idling the belts make noise. Could it be the tension pulley.


it could be the tensioner, water pump, alternator, A/C compressor, power steering, or even a really bad serpentine belt. The only way to be sure is to remove the s-belt and spin-check the pulleys and listen for squeaks or grinding bearings.

2002 chevrolet pick up v6 excessive noise from belts replaced idler and tensioner ,no help power steering works fine ,altenator charging, a/c ok water pump ok rotated altenator, by hand when changing...


I would suspect the altenator, A/C pulley, or the belt. when you checked the altenator and a/c they have to turn smoothly with no play or roughness. If these checked out fine then I would check the belt, they do stretch.

Stiff turning


you could be low on pwer steering fluid. CV joints won't affect steering. That is for powering the wheels.

Very important. Make sure shop did not overtighten a/c belt. If they did, you could be in danger of breaking your crankshaft snout. It may be a good idea to check that.

Also, did they tighten the power steering belt correctly?

Did this steering issue sstart after repairs

  1. The tension for the water pump and power steering drive belt should measure 603-691 N (135-155 lbs) for a new drive belt, 495-583 N (110-130 lbs) for a used drive belt. The limit for drive belt tension is 196 N (44 lbs).
    1. Adjust the water pump and power steering drive belt tension as follows:
    2. Raise and support the vehicle.
    3. Remove the RH front fender splash shield (16102).
    4. Loosen the water pump and power steering pump drive belt idler pulley locknut.
    5. Tighten the drive belt tension by turning the water pump and power steering pump drive belt idler pulley adjustment bolt counterclockwise.
      1. Tighten the water pump and power steering pump drive belt idler pulley locknut to 33-37 Nm (24-28 lb-ft).
      1. Install the RH front fender splash shield.
      Deflection Adjustment
      1. NOTE: If the drive belt has been in service for some time, it should be inspected before adjustment. A drive belt that is severely glazed, frayed, cracked, or contaminated with oil must be replaced. Minor cracks in the back of the drive belt are acceptable as long as no large pieces are missing.

        Apply 98 N (22 lbs) of pressure to the drive belt at a point midway between the power steering pump pulley and the water pump pulley.
        1. NOTE: Always check the drive belt deflection when the engine is cold, or has been stopped for at least 30 minutes. A drive belt is considered new if it has been used on a running engine for less than five minutes.

          The drive belt deflection should measure 8-10mm (0.31-0.39 inch) for a new drive belt or 10-12mm (0.39-0.47 inch) for a used drive belt . The limit of deflection is 16.0mm (0.63 inch).
        1. If the drive belt deflection is not as specified, adjust the water pump and power steering pump drive belt tension. Refer to the procedure in this section.
------------------------------------------------------
  1. The tension for the A/C compressor drive belt should measure 603-691 N (135-155 lbs) for a new drive belt or 495-583 N (110-130 lbs) for a used drive belt. The lower limit for drive belt tension is 196 N (44 lbs).
    1. Adjust the A/C compressor drive belt tension as follows:
    2. Loosen the A/C compressor drive belt idler pulley tensioner bolt.
    3. Tighten the A/C compressor drive belt idler pulley adjustment bolt.

Nissan xterra 2003 car noisy problem


If it's the water pump there should be water leaking, if it's the steering pump the noise  would change as you turn the steering wheel left to right. If it's constant, it could be just old belt and bad idler and tension pully. Start buy praying a little water to the belt while the engine is running and if the noise goes away, the belt is in time to be chaged. If the noise is still there, then most likly it's the ilder bering or tension bearing. Good luck
