    When I first heard that screaming noise on my 2006 wrangler, I looked at the belt and pulleys, alternator and water pump and they were all fine than a friend with a sharper ear than mine located the noise coming from the distributor. I pulled off the cap (dust cover) and sprayed a lubricant where the shaft meets the bottom plate and it must have drained down towards the engine as the noise went away, but it came back three weeks later. I think I need to replace the distributor my problem is that I can change a distributor however all it has is a pick-up sensor that leads to a coil pack above the sparkplugs, no place where to connect a timing light and no marks on the damper. my question is how do you set the time after you replace the distributor? or is it one of those things that only the dealer or shop can do with their diagnostic equipment. any suggestions? thanks

    Is it screeching or a high pitch metal to metal sound?

    It could be the radiator fan(s) that can be causing something like this. Remove the plug and jump the fan directly from the battery to the fan conectors. with the engine off. Listen if that is the cause of the noise.

Makes squealing noise

You need to check the belt that drives the alternator for proper operation. The belt may be old and worn, or a pulley may be not freewheeling, but seized or with a bad bearing. Possibly the tension on the belt is too loose from a worn out tensioner.

First, spray a little water on the belt with engine running and see if noise goes away, possibly a worn belt. Pull the belt off and check all pulleys. Spin them by hand and see if spins easy, no rough feeling or a catch when spun. Check alternator pulley, idler pulley, tensioner pulley, PS pump pulley and A/C compressor pulley-check them all for free wheeling. If good check the tension on the belt when installed. If unsure, have a mechanic check tension with a belt tension tool.
If belt is good and pulleys good, check alternator output with a voltmeter on the battery with engine running. If voltmeter is below 13.5 volts, the charging system is still not working properly. Have it checked out.

Making a chirping noise while driving

Most chirping noises are due to bad pulleys on the motor. It's usuually an idler pulley or belt tensioner pulley. May also be the bearing in the alternator. Use a stethescope to check otherwise you can use a rubber hose. Put hose up to one ear and put other end by each pulley. Should hear high pitch chirping.

I own a 2007 Jeep Compass 4x4 with about 74,000 miles on it. Recently the engine started making a noise. I was told it might be the upper & lower idler pulleys and tensioner pulleys. I called around...

The first thing I would do is remove the serpentine belt and then start the car. If the noise is still present than I would agree that the noise is in the engine whether it be the timing chain, valve train, etc. If the noise goes away than it is being caused by an accessory. Water pump, alternator, a/c compressor, p/s pump would be suspect. You can run it for a couple of minutes with out the belt at most. This will keep the engine from overheating since the water pump will not be turning with the belt removed.

Rattle noise coming from belt

this could be a bad pulley or alternator, you will need to remove the belt and spin the pulleys by hand to see which one is making noise, it could also be the ac compressor pulley, start there.

I need to replace the idler pulley/tensioner and the belt

When this idler wears out it makes a growling noise that changes with engine RPM. A Bad Idler Pulley May Wobble & Wear Out Your Serpentine Belt Prematurely. Get Rid Of That Horrible Noise & Change.

Remove the serpentine belt by using a breakover bar, ratcher or serpentine belt removal tool with the correct size socket for the pulley mounting bolt. Rotate tensioner arm to release tension. Remove the bel. Using the proper size socket, remove the tensiones mounting bolt and remove tensioner.

Before installing the new tensioner, make sure the mounting surface for the tensiones is clean and free rust or other obstructions. Find the locator pin hole and rotate the replacement tensiones until the locator pin and the hole line uo. Insert the pin into the hole. Reinstall the mounting bilt and torque down to tight fit.

Rotate the tensioner arm to install the serpentine belt. Make sure the belt is correctly fitted to all pulley in the drive system. Start the engine to check for any problems. Extreme care should be taken when reinstalling the serpentine belt because some of the pulleys are located in remote positions ans it is very hard to see that belt is seated properly in all of the grooves. If the belt isn't seated properly, the belt can "ride out" of the grooves and the belt can be damaged.

Also must review the ZJ Repair Manual Secc-7-Cooling-System for graphics references.

Hope helped with this. Remember rated this help. Good luck.

A high pitched whining noise in the engine.

This Noise Description sounds Indicative of the Sounds that come from the Serpentine Belt Or Related parts such as Belt Idler Pulley or Belt Tentioner witch also has a Pulley, but if Tensioner itself is Literally BROKE I've replaced a number like this it will cause a Whining noise . Best case scenario its just the Belt, and if any of the other Problems turn out to be the Culprit the Belt MUST be Replaced Anyhow as Damage is Being caused By the Very Whining you hear.
PLEASE Spend the Extras $ for the BEST BELT as this Drives your Water pump, Alternator, A/C Compressor, Power Steering Pump All Crucial to Control of, easy Steering ,All Electrical-Power Distribution, The COOLING of Engine << VERY CRITICAL Component
The Pulleys usually have a more Hum type Whining. So I would say at Best The BELT , And WORST Belt Tentioner is Broke
