OK folks--need some advice please! 2005 Honda Pilot EX-L, about 90K on it.

Had two mechanics so far--

#1
July-Had new alternator installed
Week later--squealing on idle and acceleration==new belt installed
Week later--more squealing--replaced belt tensioner (new design model?)
Week later--another brand belt installed, replaced pulley on alternator

Quiet for about two months..nice.

Two days ago, my daughter starts it up, squealing for about 15 seconds then stops, not on idle or squealing--just that initial start in morning. Tried the next morning without the defrost off at first--squealed anyway.
Called #1 to see if he wanted to try to fix--he basically threw in the towel and said he doesn't know what it could be. NICE.

Called #2--said right away it's possibly the battery (shy of 3 yrs old)
explained the voltage pull in mornings. Took it in. He heard it too. Starter tested GOOD, Alternator tested GOOD...Battery tested, GOOD, BUT NEEDS CHARGE. He also cleaned some pulleys and air hosed the AC Compressor out. Mentioned slight dry rot on Crank pulley but he wasn't overly concerned.

So, we replaced battery.

Next morning? Yep....same sound, although shorter it's still squeals. Another mechanic (not #3 now) said it was because it was wet outside
So, using that logic, EVERY car outside would sound like that in the morning? Ok, thanks.

Please!! Tired of throwing money at it but it NEVER made that noise at start up before last week.

Thanks!

 

Welcome in,get someone to start the car with you listening for where the sequel is coming from look to see if the belt is actually slipping or rubbing a pulley,it maybe that the new alternators guide is slightly off,if it's not the belt it may be a bearing ,I have purchased new alternators and the bearings lasted a week.sorry you had to pour so much money into this and still have the same problem.good luck.

 

Thanks-could the alternator still test GOOD with bad bearings?

The Mechanic said to give it a couple of days--it ACTUALLY STOPPED squealing for about two days...this morning? Louder than ever and it doesn't go away completely anymore--chirps when it hits a certain spot.
