Tiller88 · April 8th, 2008, 12:42 PM

Hey guys so my gf's ford focus makes this whine noise like a supercharer...

Im kinda concerned its been doing it for awhile i just want to make sure its not going to hurt it it only does it when you accelerate

Its a 2007 or 2008 with 36k miles on it

any ideas?

alternator

Tiller88 · April 8th, 2008, 12:44 PM

seriously? It seems fine like everything works its been doing it for about a month it hasnt died or anything?

Is there a way I can check it before I go and replace it?

Will ford cover it? (still under warranty)

HMUSN · April 8th, 2008, 12:47 PM

Ford should cover it.

pull it and have it tested is all.

Tiller88 · April 8th, 2008, 12:48 PM

ok thanks will have FORD do it soon as I can

Would have never guessed didnt know they whine? Why do they do that?

Just wana learn why

HMUSN · April 8th, 2008, 12:49 PM

it's an electrical component.

when you hit the gas it spins faster.. hence the whine gets louder.

it shouldn't whine

Tiller88 · April 8th, 2008, 12:51 PM

ok thanks I'll get on it, Hope FORD doesnt argue to much

O its not the alternator who ever told you that is dumb etc etc

They are dumb in WV and dont want to work...

HMUSN · April 8th, 2008, 12:51 PM

Just to eliminate any confusion for the future, if it has a chrome bar grill like the fusion its a 08+ if one similar to the new edge mustangs its a 2000-2007

Tiller88 · April 8th, 2008, 03:51 PM

ok its a 2007 thanks didnt know the new ones had chrome grills

My Cobra does a similar thing, but it's interference in the electrical system getting piped through the a speaker.

Tiller88 · April 8th, 2008, 09:12 PM

O NO this is DEFFIENTLY outside under the hood... Its really funny ricers pull up and ask if I have a supercharger I smile and say yes and they just leave...

I used to say no untill they said well lets race so I started saying yes so they drive off lol

GTblackprodigy · April 18th, 2008, 12:24 AM

maybe it has a supercharger..lol

aftermarket stereo?> alternator whine?

FoxHoss · April 29th, 2008, 02:35 AM

vacuum leak? idk just a late night guess... im tired... goin to bed.... godnight

could be a LOT of different things. hook a funnel to a short piece of hose and use it listen to various parts under the hood (funnel end to your ear). you can isolate strange noises pretty easily that way.

make sure you check your PS fluid level...that would make some noise if it's too low.

It COULD be bad bearings, although after 36,000 I doubt it. I only say something because my 2002 F150 started making a whining noise like a supercharger and it was the bearings on the idler and the tensioner. If you eliminate other possibilities a good way to check if the bearings (it would be the idler or the tensioner if anything) are gone is to take a LONG screw driver and hold it on the bolt that holds in the bearing and put your ear on the end of the handle. If it sounds like its running rough (I can't describe it better than that) then its your bearing. If it is the idler or tensioner don't buy it from Ford because they will not sell bearings (at least for F150's) separately and you have to buy the whole assembly so just get a non Ford bearing and swap it.
