whining

[sseaman]

I have search and still am continuing to search...The problem i have noticed is when i am between 1500-1800 rpms there is a new whining that has not been there before. i checked all fluid levels, and do not notice anything else out of the ordinary. I will have the wife help me check tonight. any thoughts?

Need more info on noise

Is this when your stationary vs driving, or both
Where do you think the sound (what direction) is coming from.

Need to first isolate between drivetrain and engine.

If it is more of a whistle, could be from muffler, exhaust.

it doesnt matter if parked or moving, i can reproduce both ways, it does seem though if you are throttling through that range or have a little more torque ie. going up a hill you do not hear the noise. i put the new muffler mounts on an this changes nothing. it sounds like a deeper whistle. i will have to wait till the wife can hold the pedal while i look

Listen around the cats, exhaust and resonator.

I guess you need to isolate it to an area, An engine compartment noise of this nature would be completely different.

romer i have read some other post that point to ps pump and temp change have you noticed this before, i bought the lc this summer so temp are just starting to drop around here, the po didnt seem real bright as im starting to find out.

have you changed your belts lately? I had a whining problem with the napa v belts. they do not sit in the pulley's far enough and the ribs catch the air and whine.

the belts were replaced shortly before i bought it, they are not oem but this just started, thats why i wondered about the temp thing? it may have nothing to do with it either

Phew, when i saw whining as the heading I thought it was a thread about my wife.

i now the feeling that whining will come when i tell her i need to buy some more parts. I noticed after driving this am for 35-40 min the whining or howling was not there, hope maybe to narrow down soon.
