I have a 2006 Ridgeline that has a squeaky noise coming from the right side of the engine compartment. The belt was replaced first, but two days later the noise was back. I have replaced the idler pully and tensioner, the noise came back the next day. Any answers or ideas?

 

Totally different vehicle, but I heard a water pump on a crown vic make a terrible squeak noise... It was very unpredictable, even went away at times.... Judging by the location of your sound, it may not be too crazy right?!?!? Also, keep in mind waterpumps have very tight tolerances. Very easy for a fin to contact the housing of the pump.

 

Thanks, I think the service guys did not put a new belt on after installing the idler pulley and tensioner, might also be the alternator.
