[SLEEPERSTATUS]

over the weekend i changed out my alternator and once it was all put back together and i fired it up there was belt chirp or a pulley noise cant quite tell yet. almost sounds like its coming from the #4 lower but yet i never ever had problems before:shrug: also im lost now im hitting #15 in boost instead of #18:??: if anyone has anysuggestions on where to start with troubleshooting id appreciate it

thanks

hard to tell kind of brad it may be a pulley that the other belt goes on:shrug:

 

[Senkak]

That is odd.
Did you put your old alt pulley on the new alt?
I assume you have a larger alt pulley since you run a 4lb lower.
Check you pointer on the tensioner make sure the belt is properly tensioned and not loose.

yeah i put the aftermarket pulley on the new altternator and can you explain to me(rookie) about the pointer on the tensioner thank you

did you keep the same belt? sometimes when you change them they could stretch the belt a little. I would try using a new one.

Double check to make sure that the belt is run properly and seated in the grooves.
Other wise I'm at a bit of a loss.

Your welcome!
I'm glad to help my west coast connection.
Did you find the problem?

Does the belt appear to be running true when you watch it?

.

Check to see if the alternator is working. Just cause it came off of a shelf at a parts store, doesn't mean it's working properly.

well i looked at it a little before it got dark lastnight after work and im noticing that the lower has wobble to it....more than id like to see:shrug: i dont think i did anything wrong while changing out the alt and the belt is on correctly so i dont see whats going on and why im loosing boost

 

[03cobra#694]

Just curious as to what kind of vac you`re seeing at idle Anthony?

Yeah, that's what I was wondering about.......Are you sure you got the lower bracket/spacers all back together properly?

i hope so.....my buddy at his shop did most of the alt work....i was there but more to watch.....so now where do i start? do i unfortuantley take it back off and start over? do i check my lower make sure thats tourqed right? now how would i even know by looking rather or not the spacers got put back together correctly?

 

[JB]

You might have to take apart and do over to make sure it's correct

I would start by checking that all bolts are tight

Do you have the instructions/partslist for lower install?

i just might still have them....damn what a PITA lol thats what i get for letting other work on my ride i guess.....wonder if i can put it on the lift and tell by just looking to see if it is together correctly instead of taking it all apart again....btw thanks for your help:beer:
