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.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.
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?
