alternator

[tylerdelaney]

well i swapped out my alternator and put another one in because it was squealing the belt.now that i have the other one in it is no better.any advice as to what it might be?sorry this is for a 2.4 not 2.2

Why did you think it was the alternator, out of all of the other pulleys? And why not replace the belt? Or try some anti-squeak spray on it?

[tylerdelaney]

it is a brand new belt and its when i turn up my stereo

[tylerdelaney]

would it be possible that it could be my battery because i dont even know old it might be

[[ion] C2]

So what the fuck is going on? Is the belt mechanically squealing or are you hearing "alternator whine" through your speakers? :lol:

Whine is almost always caused by a ground loop. (in my case it's caused by a supercharger)

[cherrington17]

loud squeel through your speakers is alternator whine. you have a bad ground somewhere.

[tylerdelaney]

no it is the belt i am 100% sure of that

[cherrington17]

the belt you'd hear outside the car... it would have ZERO impact on the volume of your speakers.

[tylerdelaney]

no it seems when i am taking alot of power from my battery it will start squealing.there is no whining sound through my speakers.my old belt never squealed and when it broke i had to drive home (5 miles) in the dark and since i put the new one on it has been doing it.(by the way i do have a little system installed)

[cherrington17]

your alternator won't make noise depending on drain.. it only supplies X amount of power. you can't draw more then it puts out.

and your battery won't make any noise at all.

and a "small system" won't drain enough power to do anything, other then kill your battery.

[tylerdelaney]

can it be my batt. or should i try the big 3 i just want to get it fixed so i dont get embarassed when i turn up my stereo

i don't think you're reading anyone's posts http://www.xceedspeed.com/forums/images/smilies/rofl3.gif

fix your botched wiring

[cherrington17]

so.... lets start from the top.

Your car squeels when you turn the volume up on your stereo. So you swapped your alternator, its still doing it, so you swapped it again.
When did the squeeling start?
What kind of "system" do you have? (aftermarket headunit, speakers?, subs?)
How is it wired?
Who installed it?

[tylerdelaney]

i broke my alternator belt the other night .i put a brand new one on and it squealed ever since.i changed the alternator today still squealing.i have a pioneer hu,1200 watt sony xplode amp,1 10"type r,1 10" infinity kappa perfect,and a 1 farad cap.i wired it myself.i have been doing so for 8 yrs now.

[cherrington17]

the belt would have absolutely NO impact on whats coming from your speakers. Putting a new one one, wouldn't make a damn bit of difference when you adjust the volume.

[tylerdelaney]

it is not coming from my speakers.it is from my belt.my belt squeals not a whine in my speakers.

[tylerdelaney]

it squeals when there is a load put on the alternator and when i first start my car.

[Redog]

Is it the right size belt?

For somebody that's been installing audio equipment in cars for 8 years should know that the belt is in no way connected to the speakers.

I know very little about car audio systems, and even I know that what you are asking really doesn't make sense.

Sorry, man

Ha, my fuel pump does that, sorta.....:)

How can you be convinced that it is your belt when you were convinced before that it was your alternator? Yet the belt is brand new? :lol:



Could be any one of the pulleys.

[tylerdelaney]

ok i guess i forgot to say that this has nothing to do with my speakers.someone just thought that is what i was talking about and i never corrected them for it.the sound is from the belt and the speakers are fine.

[tylerdelaney]

i also changed the ac pump and still the same im running out of options.

[CactusWill]

Why are you replacing all the most expensive stuff first? Do you wanna spend thousands only to find out that it was a $15 idler pulley?

[Redog]

AC Pump? Do you mean the compressor?

So you spent $160 on a alternator, $800 on an AC Compressor, without knowing what the problem is in the first place :eek:

Why do you take it to a mech's shop and find the problem and fix it right without throwing money at it

[Redog]

Good point. How many miles on the car? Idlers don't last forever, esp those plastic ones ;)

[tylerdelaney]

i already had them lying around the shop so i decided to swap them.

[tylerdelaney]

135000 miles on the engine

[Redog]

Stop, put down the wrenchs, buy an idler/tensioner.

$40 for the entire unit (LA1/3400 price)

[tylerdelaney]

i have one of those also so ill try it tomorrow

[Redog]

Tensioner should be replaced at that milage anyway, but I wonder if the belt you have is too small, that would explain the squeaking.

I know about the tensioner, mine melted and cut the belt in half. The car still ran fine, but it wasn't going to run that way for long.

[tylerdelaney]

i bought it at napa auto parts and this is what they said fit
