hi guys
quick question - I'm sure all NA owners know this high pitched whining sound that usually comes from the mr2 engine - what is that ? alternator or oil/water pump ?
exactly this sound - high pitched whistle : http://www.youtube.com/watch?v=QA0DBtx34jc
I'm a bit concerned as my car this evening didnt make that sound for a sec, then after a loud screech from a belt it started whining again.
Just wondering what's on the way out
cheers

Re: the characteristic "whining" sound... alternator ?
just been looking over some photos of the 3sge and if i understand it correctly i could tighten up the alternator belt myself quite easily.. just asking this before Luke is going to kill me for showing up at his garage 3rd saturday in a row
how much tension should there be in the alt belt ? I can easily press it down with my finger.

Re: the characteristic "whining" sound... alternator ?
dont know! i thought it was the alt, but not sure now, it seems to be coming more from the top of the engine ? ... hopefully someone will know.

Re: the characteristic "whining" sound... alternator ?
i had a similar sound from a vectra once when a cambelt idler was sticky. perhaps its cambelt related?
EDIT: also had similar sound from our old car when i changed the alt belt and it was too tight, just remembered

Re: the characteristic "whining" sound... alternator ?
hmm.... i dont know. I just took it for a spin and it seems ok. but in the morning struggles for a bit, the whining sound is gone, something (belt) screeches loudly and then something (lol, alternator?) starts, the whining sound is back. I'd think the belt is slipping and alternator has some trouble starting to move, but not sure. I'll start it tomorrow morning while looking over the engine bay, perhaps that will give me a clue... the alt belt seems a bit loose if anything, I can easily press it with one finger.

Re: the characteristic "whining" sound... alternator ?
mine make this noise as well! I thought it was the alternator also, however one of my belts has started screeching now (and the noise stops) then its back when the screeching stops
damn you cold wet weather!

Re: the characteristic "whining" sound... alternator ?
I have this sound on my Rev1 N/A.
Only picked it up today. Few mates who are on here think its the alternator belt being a bit tight.
Will try and have a look over it this week.

Re: the characteristic "whining" sound... alternator ?
cool, let us know what you find.
My belt is pretty loose, if not too loose. I dont know how tight should it be and how to measure it without any tools. I've browsed thru some forums and apparently it should be so you can twist it with your fingers only about 1/4 of a turn. Mine is a bit floppier than that..

Image it's an idler pulley, mine makes the same noise with an induction kit on it.
Re: the characteristic "whining" sound... alternator ?
could be. On a cold morning I can clearly hear that it has problems moving; for a couple seconds engine is really struggling, but frees up with a screech quite quick. Hopefully not terminal yet, I really wanna stay out of the garage till new years

Re: the characteristic "whining" sound... alternator ?
Hmmm mine only seems to do it some of the time and mainly in 1st, 2nd and 3rd.
I'll have a look at it on Friday probably, half day at work

Hadnt noticed it in idle, not in higher gears that I have noticed.
Turned everything off for a good listen while driving it home.

Re: the characteristic "whining" sound... alternator ?
heres a (rubbish phone) video of mine making that nose
http://s810.photobucket.com/albums/zz28 ... 010001.mp4
It seems to rise with revs, stop at a certain point, then come back again at lower revs (or when i put the fogs on!!)
