Thread: 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

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.

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

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..

I made a video that I will post up here in a second so you guys can listen to the noise itself. Would I just have to add more power steering fluid or would I need to flush it?

Where is the throttle under the hood?

the charger without an intercooler can get up to untouchable temps in under an hour of driving.
