Engine Whining

I'm thinking it's the supercharger... but it's pretty loud and only happens when I accelerate. I haven't changed to a CAI or anything like that and it's completely stock.

Just in case it isn't... What else could it be?

Thanks in advance,

Garrett
 


LOL could you describe with any MORE detail other than my supercharged engine is "whining". Superchargers whine, other problematic parts could be a squeaky belt, bearing in any pulleys going out, hubs tend to growl but still could be, brakes squeal but could be, etc...

A video would be most helpful but most likely its the supercharger. Stock 97-03 can be heard above 3k under WOT, a 04+ can really be heard above 3k at WOT
 
Definitely,

It happens below 3000rpm as well. It's a 2007 Grand Prix GT SE with the 3.8L. It's got almost 50,000km and I bought it one year ago at 32,000. Should I get it inspected? It was when I bought the car and the CV joints etc were replaced.

The whine is there when I accelerate and when I let go of the gas it stays for a little bit until a certain RPM. I haven't checked it really well.
 
It's not when I'm turning though... That's the thing. My uncle's Impala had low steering fluid and I could actually hear it when he was turning whining really bad. I have to get my oil changed here soon so hopefully they can check it all out.

Any more help would be great.

Thanks again,

Garrett
 
I agree with Bill, check that first... it's only like a 2 minute check and if that is the problem you're saving a lot of grief right off the bat... low hanging fruit first, man!

My 08 GP would whine like a ***** under acceleration, and Im NA. Sometimes it would get so loud you couldnt hear the rest of the engine over the whine.

I checked the ps fluid eventually and it wasnt even showing on the dipstick, very low... topped it off and the whine is still a tiny bit audible but nowhere near the volume it used to be. I think I just need to renew the fluid all together, it might be contaminated.

Turning or not, if the engine is on, the PS pump is pumping. Eliminate the obvious that way you don't take it to someone and they "claim" that it was low and they topped it off for you when they did no such thing and charge you for it.
 
I get engine whine as well sometimes, does the supercharger have fluid and does it need to be changed every once in awhile.

The supercharger rocks but I really don't have a clue on how it works.

I was doing 120 in the kentucky hills on the way to mammouth cave and it just pulls the car up the hills, saw other cars gasping for air.

It was great :D

Is there any specific type of power steering fluid I would need to put in? What about the supercharger fluid? I'll have to check it once I get home from work.
 
try checking you tensioner pulley that uses the supercharger belt.. mine was whining abnormally loud and the pully finally broke off,,, it had a bad bearing.... but that was the problem for me,, very easy fix..
 


sounds like sc whine, witch is normal, try a vid parked with the hood open and rev the engine while taking the vid, dont over rev it just goose it some.
 
97-03 should be on the throttle body, where the air cleaner tube hits the engine, should be 2 cables, new cars are fly by wire, you will need some to push the gas pedal for ya.


edit: i just saw you got a 07, someone needs to hit the gas pedal for you while you are under the hood.
 
I went to my pontiac dealer yesterday and picked up two bottles of 4oz supercharger fluid for my GTP for $24.

After I get a squirt bottle from the dollar to store to reverse siphon the old supercharger fluid, I am going to change it out.

The car has 80,000 miles on it and the supercharger has never been touched or even mentioned by anyone, lol.

I looked in the manual and it said check the fluid level every 30,000 miles, it didnt say change it, just check it but I'd rather switch it out with all new fluid.

The dealer said make sure the engine has been sitting awhile and is cool before changing the charger fluid, is this true?

Thanks

Unless you baby the car everywhere and never get into boost (doesnt happen :p) The fluid needs to be changed @ 30k miles. Fresh fluid will go in clear, after avg driving it will go brownish, when it gets dark (like normal oil) its time to change it out

While your out get a good set of dishwashing gloves if you don't have any latex ones already. That oil will be very VERY foul smelling and all the dawn and orange goop in the world will not wash that smell out if you get it on your hands and it soaks in. Trust... I didn't think it would be that bad, like oil it stinks but itll wash out. Not SC Fluid... its something else :th_jester: GF wouldn't let me touch her for 3 days because my hands stunk

Thanks for the heads up about the smell, the dealer said the same thing, something else I can get at the dollar store along with the water bottle for syphoning, lol
