I have about 150,000 miles on my original starter and I heard WEEEE noise when I started up the car. I got it replaced and now I still hear the noise particularly when it is cold and/or when I have the AC or heat on. Sometimes that doesn't even matter. Doesn't seem to happen when everything is warmed up though. Any thoughts on what else it could be?

Thanks,

 

alternator !!

grab a long screw driver, put 1 end on ur ear and the other end on the stuff under the hood, try to see whats causin the nosise. might be the idler or alternator

 

I have the same problem with the new cold weather present. I just had the alternator replaced about 2 months ago with a brand new one. Makes the same sound you are describing...I would also benifit with information

 

My car squealed at start up and it was a belt that was really worn and needed to be replaced, maybe that's the problem?

 

its most likely the belt! Tighten it and see what happens.

 

i'd suggest the belt, it probalby loosens up after a few minutes and stops squealing or lessens.

 

i have the same problem, along with most of you it stared once cold weather came about. the engine make a sharp screech at start up when cold. after it's warmed up tho the sound isn't made. belt? what one?

 

I agree with the belt suggestion. The squeeling is more than likely caused by a loose or worn out belt. However, the way you talked that it does it with the a/c on can describe other problems...as in the a/c compressor freezing up. (I doubt this though...probably just the belt)

 

The belt isn't too worn as of right now. I just replaced the factory pulley with an underdrive one and a brand new belt probably within the last 5,000 - 7,000 miles. Might have to go and tighten up the belt with the tensionner. How can I tell what level of tension is right?

I will have to give it a try later in the week. Right now I am studying for my Net+ cert on Thursday, so Friday will be the time to test this. That and put a screwdriver to the alternator or the idler pulley to check those as well.

 

belt for sure, tight it and it will not make any more sound.
mine and my bro's max had exact same problem and both of them are solved by tightening the belt.

 

n00b question but how do i tighten the belt?

 

get a haynes manual and itll tell you, thers a tensioner that takes care of that

 

Tighten the belt...just did it last week as mine was making a horrible squeeling sound.

Didi it in less than 30 secs...

 

yeah i have the same problem it just started to happen since the weather got colder

well could it be the compressor?
my compressor is messed up and makes a loud noise while the engine is on so i need that replaced
last week i got the pulley replaced
but how you tighted up your belt?
can someone show the us how to do it step by step?
thanks

 

I have exactly the same problem - engine squeals for a while cold and as it warms up the sound goes away. My first guess is the altenator but I'm not so sure of that considering my 99 has just 60'000 miles.

The engine squeal occurs regardless of outside temperatures. +90/-30. It's just when the engine has been idle and cooled off.

 

Timing chain tesnoiner of flywheel teeth gear if it is not the belts. Or could be a bad starter? Rebuilt does not always mean better.
