Question about 1997 Jeep Wrangler

Timing on a 97 wrangler

When I start my vehicle (4 cylinder automatic) there is a loud screeching noise that sounds more like a metal chain going around instead of the actual belt. It increases with rpm's, the faster I go the louder it gets. However when i am at rest with the engine started it's not there. I think it is my timing but have not checked. I was told to take the belt off and run engine for 20 secs to listen to my pulley's..am I on the right track ..If not, I need backup .Help!!! Thanks, Jake

If the noise is still there with the belt off its probably the timing chain

Hi Jake. With the hood open and the engine at idle, find yourself a 3 or 4 foot long small wooden dowel. Then have some sit in the jeep and slowly bring up the rpm's, when you here the noise beginning, press the end of the dowell onto the different parts of the engine, while keeping the other end of the dowell against your ear. When you find where the noise is coming from, you will be left with no doubt.

Cluth is making a loud screeching noise when changing gear and when starting the car up.


Is it squeeling or a sound like metal to metal as if it squeels, then perhaps your alternator is getting bad or your serp belt, if its the other than perhaps your clutch maybe going start with the clutch flywheel hope that helps

There is a loud slapping (metal too metal) noise coming from the driver side # 3 or 4 cylinder as soon as you start the vehicle. The more you press the gas peddle the faster the sound


Could be stuck, and now bent from the contact with the piston. This could get expensive. Does the engine run ok other than the noise or is it missing - if the valve is stuck open it should be running rough from the misfire on that cylinder.

Screeching noise coming from driver side tire


The high pitch sound may come from the brake pads as metal parts hit the disc to signal the owner that it needs change. The metal parts gets exposed when the pads have worn out. The brake also has a hub to cover the disc. See if the metal plate is hitting it but this issue would appear when the wheels are in motion. Check if it is the belts, have the tension checked out. Other than that the bearings are the other items on your wheel that could cause a high pitched sound when you car is in motion.

The fan clutch was replaced but the same noise which sounds like an airplane taking off is still present when accelerating at any speed. Does the fan motor need to be replaced also?


Could be your belt tensioner is worn out and needs replacing, common for a 10 year old vehicle. Is it a loud squeeling noise? if so then it's the belt slipping and rubber on metal pullys is a loud screeching noise

Replace front drive belts. There comes a time when they get so worn and polished that they just don't grip anymore.

A loud sound shortly after starting my car


I'm guessing that you Expedition has been making this noise probably since you've had it? Even if it hasn't, I think I can bring you some comfort. If you could pinpoint where the noise was coming from under the hood, would you say that it's somewhere over on the passenger side? My dad owns a 1998 Ford Eddie Bauer Expedition, and we noticed a loud noise with the same habits as what you're describing. Come to find out, there is an air compressor under the hood, I can't remember exactly what it's for, but the sound that I believe you're hearing is the compressor filling up with air and then shutting off once the proper amount of pressure is reached. You might try popping the hood to try to locate the exact place that it's coming from, but I can tell you that it's probably a 99% chance that when you find your noise, you'll find the compressor I'm referring to. Hope this proves to solve your issue and helps to ease your worries. Have a wonderful evening!
