Thank you guys very much

Thank you. Learning.

Where can I get this lube from please

I just want to thank you amigo, my 2017 Escape just started making this noise today and after watching a video I was freaking out thinking it was my tranny.

How to read 0.55 thank you

Great information thank you 😊

Ok..what's the problme here ..from which part in the alternator in this case??

am a tool maker the plug diameter is 13.6 and must be impreil English but i lost my thread gauge but i did not check my TPI i what to buy tape then tape 1 hole itsgoing half way .is it uif Bsf its the plug of Ford ranger petrol

Thank You, very informative.

Thanks A lot This Helps Me In My Job Workshop ❤❤

Loved your presentation!! Clear, concise and informative. I was waiting to see if you were going to make any mention of Whitworth. Are they determined more like the Metric or the SAE. Thoughts?

Perfect. Exactly what I have been looking for. Thank you for such an amazing tutorial video.

Meanwhile at Boeing: "wait, what's a bolt, does it cost money?"

Thank you for the lesson

Well damn! My 2011 RAV4 just started making this noise and I was sure it was a developing tranny issue!! I'll be trying this test and scoping out alternators now! Thanks for the vid!

That's literally the sound mine makes

In a metric bolt the number on the head is not considered a decimal number. Instead, it consists of two independent numbers separated by a dot. The first number indicates the bolt's tensile strength, and the last number represents the yield strength as a percentage of the tensile strength. So 10.9 means: tensile strenght= 1000 Mpa (=1000N/mm2) and it yields at 0.9x1000= 900 N/mm2. 8.8 is the base level, I have never seen anything less. 10.9 is the strongest You can get with corrosion protect coating. 12.9 is just bare steel. But I learned a lot about inch stuff. Thanks

You Saved My Life! I thought had something messed up with my engine from being too low on oil or something. Unplugged that cable and the noise went away! I bought myself an alternator and slapped it back together and it's running nice and smooth again! Thank you so much! 👌

Thank you

Great info, I was very confused before watching this video.🍻🤠🇦🇺

I have a 2005 Toyota Prius with the same sound. I went to Toyota dealership and two other mechanics. They all said I would need a different engine/swap. Over $5000. God bless you for this video.

Thank you for this vid! My camry is making this noise, but much softer.

A two minute video with a 25 second intro and a 25 second outro. Interesting choice

18:36 So thats what that file looking thing is in my tool chest! AWESOME

Can the alternator whines only when stepping on accelerator pedal ( while driving of course,)?

Why this noise? It is not the bearing right?

Thank you for the video. Bingo! This is what mine sounds like.

I would expect ripple if it was a voltage regulator. Personally, didn't see any on mine, and it mostly occurs during high current which makes me think just the pully bearing.

very informative. that solved the mystery noise. Thanks brother 👍

Threads are stripped on the bolt I need to replace and it's hard to get the pitch. The bolt has YM stamped on top. Any idea what that means..

How to test itd

dang it, i think mine is starting to go bad, and at a stage just before this...after replacing my headlight assembly and testing the lights etc...I heard this exact whistle noise (minus the extra grinding in the video)..it didn't make the whistle this morning, but i also have start-up and idle issues...great, add it to my list of things to do..lol

does carbon tracking cause a misfire ? or does a misfire caused by something else cause the carbon tracking ?

I been having random, then cyl #3 misfire, back and forth. Had dist cap, rotor, wires, plugs installed. Then soon after, same codes again , so someone removed cyl #3 and there on the plug was carbon tracking. I don't know about the boot nor the other plugs. What would cause the carbon tracking ?

they're commandeerlng aIiens

dlrectors are tortfeasors they'll treat you like crash test dummies in their courses

Why would a tire cup at the location of each tread depth indicator? My tires are cupped and each low spot (cup) occurs directly across each of the tread depth indicators as if those locations were left high from the factory. Never see than before.

Thanks a lot sir for this interesting presentation , really it's useful information Best regards

So, while I am waiting for my new alternator to arrive, my guess is to unplug the alternator and charge the battery between short drives and don't drive at night. I sure ain't going to drive it while cooking the alternator...

Eggzackly! My Toyota doing the same thing. Video is great, except you didn't say what the solution was. I scrolled the comments and found most people have fitted a new alternator.

I realized this was the problem when the battery light came on and the noice went away! Good video!

Ty ❤

That's my exact problem lol

Anyone know what the background whistle/whine sound is when he pressed the gas pedal? My maxima is making the same noise.

Thank you Sir, sure enough that's what mine did too.

Can that noise go away after it runs for a min or so ?

how do I fix this? new alternator? can the diode be replaced?

What was the issue?

Weird video

Bam! There's the exact noise my car is making. Thanks. I'm so tired of mechanics looking at me like I've lost my FEMALE mind and telling me how they've been mechanics for 50yrs and such a sound doesn't exist... even when my car's right in front of them making it! Appreciate the post!
