Good evening ladies and gentlemen . It is finally fixed. My engine is purring like it was when it was brand new. Love it 😍 I took my 2015 Pilot to the dealership Wednesday they had to order parts and I had them change the water pump and pulleys. I had them check the serpentine pulleys as well as these were not changed originally. Yes I only have 50,000 miles on my Pilot but it was at the dreaded 7 year deadline. The warble noise is pretty much gone with the OEM parts. Interesting the serpentine belt being a bando belt was not riding perfectly on the pulleys, there was actually a small
difference on one side of the pulley. I saw it myself, so I had them change that belt and pulley.
I have to say I know there is discrepancies with dealerships but , mine seems to do very well when I ask for this one specific mechanic/tech. Thanks to all of you gentlemen for your expertise time and patience in giving me the advice.

Now since I have the pulsation with my brakes my next decision is Akebono brakes and rotors or Dynamic Friction brakes and rotors.I currently have 3 month old Wagener pads and Akebono rotors but I did not do a great job of embedding the pads into the rotors.
it is a long story..
The Pilot is a heavy SUV and needs fantastic brakes and rotors. I am researching this.
Interesting- had similair experience with bando serp belt. Growling noise until engine warmed up. Sprayed belt with water and noise went away. Replaced with Honda OE belt. Quiet.
Regarding that warbling noise that is now gone. Since everything was repalced- how do you know it was the Asin WP that was responsible? Could it have been the bando belt all along?

Hi Wilbur. I had that growling noise a few times also! I was not sure what it was.
I know it was the pump because I did not have the noise before the pump. The Aisin was installed and the noise started. I had another mechanic look at it and he changed the belts and pulleys to another brand, Gates USA ugh! but not the water pump. I quickly got those Gates parts out of my car! So I am thinking by process of elimination and by the good expert gentlemen on this forum it had to be that. This was also described by other folks on other forums. This time the water pump, belt and all the pulleys tensioner etc were all replaced with Honda parts. done!
Also the warble noise is 95% gone. So there is still this rhythmic type of noise, but NOT as loud!!! I just think is part of this SUV/Pilot. As I mentioned before my mechanic had me listen to a 2012 Pilot with only 10,000 miles on it and an Odyssey with 200,000 miles on it and they still had the same low rhythmic noise. I really wish I knew where it was coming from. But I have to satisfy myself and know it is just part of this cars engine. I am grateful that I spent the money to get OEM parts now with winter just around the corner I feel better about driving my car and can sleep better at night. I have learned a big lesson...when it comes to anything big,engine things etc...just go to the dealership and get OEM parts. At least there is a warranty for 1 year or 12,000 miles. My mechanic does not give a warranty for his work only what comes with the parts.
