Be sure to check the water pump. With the car running you can take a very long socket extension and place one end on different parts of the valve cover, block, alternator, a/c compressor, etc. and the other end hold to your ear. You may be able to pinpoint where the noise is coming from. This truly is a great way to narrow own a noise like this but....BE VERY CAREFUL NOT TO INTERFERE WITH ANY MOVING PARS OR HOT ELECTRICAL CONNECTIONS. THINK SAFELY AND IF YOU DON'T FEEL COMFORTABLE, TAKE IT TO A PROFESSIONAL. SAFETY FIRST.

If it is sounding kind of diesel ish (loud clacky noises towards the front of the engine) then it is because the oil holes for the timing chain are clogging up and the timing chain tensioner is not able to function correctly. Try engine oil flush and then you may need to do a couple of oil changes with 5W-20 ( go 300 miles ish in between the oil changes)and then fill her up with a synthetic 5W-20 engine oil and she may start to quite it up. I was able to get mine silent like this! Good luck!

Try slipping the drive belt (fan belt, alternator belt, or whatever you want to call it) off the engine, then run the engine momentarily without the belt. If the noise disappears, at least you now know it is not an internal engine problem, and it will be an issue with one of the pulleys, or belt-driven accessories.

I need an Idler pulley or the pulley that runs air conditioner belt as well as the belt for the power steering
OK.
If your idler pulley is bad then unbolt it and while you're at it replace the power steering belt.

REMOVAL & INSTALLATION Because serpentine belts use a spring loaded tensioner for adjustment, belt replacement tends to be somewhat easier than it used to be on engines where accessories were pivoted and bolted in place for tension adjustment. Basically, all belt replacement involves is to pivot the tensioner to loosen the belt, then slide the belt off of the pulleys. The two most important points are to pay CLOSE attention to the proper belt routing (since serpentine belts tend to be "snaked'' all different ways through the pulleys) and to make sure the V-ribs are properly seated in all the pulleys. Although belt routing diagrams have been included in this section, the first places you should check for proper belt routing are the labels in your engine compartment. These should include a belt routing diagram which may reflect changes made during a production run.
  1. Disconnect the negative battery cable for safety. This will help assure that no one mistakenly cranks the engine over with your hands between the pulleys, and that the cooling fan cannot activate while servicing the belt(s). NOTE: Take a good look at the installed belt and make a note of the routing. Before removing the belt, make sure the routing matches that of the belt routing label or one of the diagrams in this book. If for some reason a diagram does not match (you may not have the original engine or it may have been modified), carefully note the changes on a piece of paper.
  2. For tensioners equipped with a 1⁄2 in. (13mm) square hole, insert the drive end of a large breaker bar into the hole. Use the breaker bar to pivot the tensioner away from the drive belt. For tensioners not equipped with this hole, use the proper-sized socket and breaker bar (or a large handled wrench) on the tensioner idler pulley center bolt to pivot the tensioner away from the belt. This will loosen the belt sufficiently that it can be pulled off of one or more of the pulleys. It is usually easiest to carefully pull the belt out from underneath the tensioner pulley itself.
  3. Once the belt is off one of the pulleys, gently pivot the tensioner back into position. DO NOT allow the tensioner to snap back, as this could damage the tensioner's internal parts.
  4. Now finish removing the belt from the other pulleys and remove it from the engine. To install:
  5. While referring to the proper routing diagram (which you identified earlier), begin to route the belt over the pulleys, leaving whichever pulley you first released it from for last.
  6. Once the belt is mostly in place, carefully pivot the tensioner and position the belt over the final pulley. As you begin to allow the tensioner back into contact with the belt, run your hand around the pulleys and make sure the belt is properly seated in the ribs. If not, release the tension and seat the belt.
  7. Once the belt is installed, take another look at all the pulleys to double check your installation.
  8. Connect the negative battery cable, then start and run the engine to check belt operation.
  9. Once the engine has reached normal operating temperature, turn the ignition OFF and check that the belt tensioner arrow is within the proper adjustment range. Fig. 1: Often the underhood label will display the serpentine drive belt routing 88231p43.gif
    Fig. 2: Relieve the belt tension by pivoting the automatic tensioner away from the belt, then remove the belt 88231p44.gif

Loud humming/whining noise coming from engine
Remove the serpentine belt and check the pulleys on the front of the engine. There may be a bad idler pulley or other component. Replace the serpentine belt if it hasn't been done in a few years.

Check and see if your tensioner or your idler pulleys are worn on your serpentine belt.
- Check and see if your fan clutch is loose or the the fan is striking the fan shroud .
