How To Find Engine Noises -EricTheCarGuy

So this 1997 Nissan Altima came in with a really bad engine noise. At first I thought it was the alternator but it turned out to be something else. You’ll have to watch the video to find out what. The purpose of this video is to show a logical method of finding an engine noise like this. If it’s a rotational noise like this was, I like to start by removing the drive belts one at a time. If you remove all the drive belts and you still hear the noise, it’s something inside the engine. Could be the timing belt or chain. Either way, you’re going to have to dig deeper if removing the belts doesn’t reveal the source of the noise. Below is a link to a video I did on finding noises that may also help you. Along with an article I wrote about the same topic. So if you have an engine noise you can use that information to help you find the source.

  1. I have the exact same noise in my Volvo S80 from 2000. I have suspected the alternator myself but after this video I understand that it can be anything else nearby. Thanks Eric you’re best. Greetings from Sweden.

  2. Damn he's good! This was the exact same noise my 2002 Civic EX was making, turned out to be an 18 year old A/C compressor.

    Concise instructions, visually easy to learn, and very well spoken. Thanks Eric, you're a legend!

  3. Thanks for putting driveway diagnostics videos up. It seems that with your video the only way crooked mechanics can rip people off is by NOT telling the customer whats really wrong with their car.

  4. Thanks Eric! I have a Toyota Corolla that has an odd whiny noise. Will take apart some items like you said. Hopefully, it isn't gonna be bad. Blue skies!

  5. You could have easily verified that it wasn't the alternator by:
    1. It was the easiest solution.
    2. It was the first guess.
    😉

  6. Good video. My 97 maxima is making an identical noise, but after changing the idler pulley, it's still making that same exact same noise! Frustrating

  7. I am JP from Australia, n have a noise coming from the ENGINE when it is IDLING but stops when it moving > i have shown it to few mechanics, I have a TOYOTA YARIS 2006 1.3 Lt engine auto 5 dr.

  8. Thanks Eric. I jumped the gun, immediately assuming it was the alternator. Your extra effort to find the true cause of the noise was very helpful and reminded me to do my due diligence before throwing parts at a problem.
