weird sound coming from my engine, Does my engine sound normal?
Here's the youtube link to my video.

 

Sound like a bad pulley
get a

Mechanic's Stethoscope

you can hear hear the sound is coming from

 

How many miles? Maybe water pump?

 

2017 is300, 58,000 miles

 

That sounds terrible, I would not drive that. Could be the water pump but thats very early for the water pump to fail...


Thats what my water pump sounded like before it was changed, few months back.

 

60k miles pretty early for a water pump to go no? Is it covered under powertrain warranty?

 

Sounds like an accessory that has packed it in...maybe the AC compressor.
By accessory I mean something run by the serpentine belt that is not part of the engine...AC, Alternator, Waterpump, idler bearing, tensioner bearing.

 

I RR racing tuned the car, I don’t think it’s under warranty.

 

Once it's not related to the tune then it should be covered if you still have warranty.
If it's the AC Compressor, then the tune won't have any effect on it.

 

I think the noise is related to the belt. The engine runs smoothly.

 

once the car is warm, the noise is very minimum

 

I have the tune on my car and have gotten plenty of warranty work done no issues.

 

Same here. Lexus will never check(or look) for the tune, UNLESS, there is a CEL, and that they need to inspect or really check the ECU programming.

 

Thank you guys

 

it could be the water pump. The average life span on a water pump is 60,000 miles to 90,000 miles.
