Скачать или смотреть Normal Vs Bad Engine Noise Diagnosis. The Right Way

So your engine is making a weird noise maybe a rattle or tick you never noticed before. Well save some time and money by diagnosing it. All you need is a mechanic stethoscope from harbor freight. They are like $4. Simply locate the area where the noise is coming from and touch the end of the probe to it. This is how mechanics do engine noise diagnosis. It magnifies the noise so you can pinpoint it. PLEASE DO NOT TOUCH ANY MOVING PARTS DEATH OR INJURY MAY OCCUR,

Here I show you how to do it on my 2019 Ford Ranger and let you hear a few engine parts. All working normal. Except for my alternator chirping every now and then (its under warranty) You can really hear the high pressure fuel pump that is cam driven. I tried to capture the audio by holding it to the microphone. You may be able to hear it better if you turn it up or have headphones on. The fuel pump you can hear very clear.

So after you locate you where your noise is coming from then go get your parts from the parts store and install. I hope this video helped to show you how to diagnose the noise.
