Mechanic Tip on Engine Noise Diagnosis with Simple tools!

A Simple Mechanic Tip that works very well for engine noise diagnosis using very simple tools shared by a Toyota Master Diagnostic Technician with over a decade of experience.

In this video I will share with you a very simple and proven method to diagnose engine noises. Whether it's from the belt driven accessories or engine mechanical parts this method will work to isolate your noise source to make diagnosis simpler.

A Hidden lesson in this video if you are reading this description is this :

Every car repair begins with a Concern. Most DIY mechanics or junior mechanics tend to be in a rush to jump into repair ignoring the most part of any automotive repair is the diagnosis but even more important the Cause of the failure.

A very powerful tool in every professional mechanic 's arsenal is not the expensive snap on tools or tool box. But the structured approach to automotive repair. The rule of CCC ( Concern, Cause and Correction ) when applied correctly will save you many headaches and incorrect or incomplete repairs or worse comebacks.

Always spend most of your time on Diagnosis and the investigation of the Cause with minimal disassembly and less time in the actual repair once the Cause has been identified.

The loneliest guy after the Maytag repairman is the Toyota mechanic..lmfao..GOD bless you and your family..great content!

That thing ia well cared for and clean. 300k should not be a problem, with regular maintenance of course. As a ASE cert. master tech, ill share a tip that goes well with this. Take a clean 1 gallon plastic jug, cut about 3-4 inches off bottom of jug. Slide cap end over screwdriver - dowel . It acts like a loud speaker and amplifies the sound big time. Thanks for the videos bud. Stay well

[paulc]

The truck's engine looks well cared for and it is sparkling clean! I think it should be able to go 300K!

[markkrispin]

I am not a DYI type of person, but I have still learned a great deal as always. Thanks again AMD!

[Giardintek]

If he has a mechanic like you, I would tell him to keep it and drive it till 300K and beyond,
Unfortunately most of us don't have an honest mechanic, especially don't have or know one whom know what he is doing.
Thanks for the video

Tell ur buddy, go to 300, 000 miles! Looks like he took excellent car of it! (Especially w/ car prices/chip probs). U crack me up "I'm under the car, no, engine isnt talkn to u". Hey AMD, sometimes ur car DOES talk to u (tells u ur neglecting it).😉 I have always wondered who 1st thought of the screwdriver stethescope?🤔 Great video as usual! 👋

Congrats on the 10 Million views on your videos! If you get an award let us see it!!!! AMD is a rock star, y'all!!!

good trick with the screwdriver...an old timer showed it to me 30 years ago using a wooden dowel.

[robertkeefer]

If that was my truck, I would say go ahead and change the water pump as well. The play in the bearing is a concern.

[dc]

Keep the 4Runner until 500, 000 miles. I just did the water pump on a 2005 Toyota Avalon and replaced the idlers and the tensioner pulley only. I leave all my Snap-on ratchets in the "OFF" position after use or at the end of the day because easy to overtighten a nut or bolt when trying to remove it and shearing or stripping the thread.

Great video
Been using long screwdriver for over 40 yrs
Then remove belt and rotate for rough bearing

Well done! There is another case of noise being the answer, but being a Toyota mechanic you may not see it much. Exhaust leaks from one branch of the exhaust manifold can imitate a rod knock. Nissan had a lot of problems with broken exhaust manifold studs in the 1990s. The tap-tap-tap sure sounds like a rod knock, but listening to the engine block reveals that it can't be heard on the engine, only in the air.
That truck sounds so much better fixed!

Parts doesn't exist can't go bad. Good to have hybrid. Thank you AMD. 😊

[moose]

AMD, another great instructional video. Sometimes the diagnosis can be as simple as isolation (your example), migrating a suspect part with another part (coil packs are a good example) and see if the problem moves or testing a suspect part with a known working part. Keep up the great work.

[MrNextMx]

already pass the 300k miles on this toyota corolla/geo prizm I just bought, man I don't know how long I driven since the speedometer broke probably 1k miles, the car drive like a dream.

[Ratlins]

Thanks, would never have thought to remove the belt to help isolate the noise. This is a great tip and your channel is terrific.

[mrvang]

My '09 tacoma had over 250, 000 miles on it and still runs like a brand new truck from the dealership. Only thing that I had to replace on it was the timing belt, the belt tensioner pulley and a new starter that finally went out. Went to the dealer to get the exact starter part and took me about 10 to 15 minute to replace the starter. Very easy to work on, which is why I will be buying another tacoma in the future.

[christianmondragon]

This is probably one of my favorite videos. I just love all the information you give as you're working on an actual truck or car.

[daniellel]

Keep going!! Have a 2003 with 280K and a 2020. We store the 2020 and plan to drive the '03 until the body gives out. Engine is great, just not so pretty. Clear coat is peeling and the once red is now sun faded but she still starts and has gotten all her oil changes. I will say the 2020 interior seams to scuff easily.

I could watch this bloke all day and watch the repeats again
