I have a manual 1998 toyota tacoma. There is a whining noise coming from the engine when idling, but the whine gets really loud when I accelerate. I had the belt replaced thinking this would fix the problem, but it didn't.
SOURCE: my rav4 sounds like a jet engine. a constant whine
i am thinking might be fan belt is slackening ,u need to tighten the belt up

well it could be a few things but most likely you belt is sliping. That is very common and happens to all cars over the years if the belt is not changed. You should check it out. The belt could be bad but it could also be a bad pully. If you dont know what these parts are look them up on google. its very simple

Some questions:
- Does it happen when standing if you raise the RPMs up to 2-3,000?
If yes, listen closely to the alternator.
- Is it related to road speed?
If so, then you should put it on a chassis lift, wheels free, then cause it to happen by putting it in gear and raising RPMs to road speed.
I suspect it isn't the acceleration that causes the pitch to change but rather engine RPMs.
You could check this while on the road by starting in a lower gear and noting when the whine is very noticeable, then slip into the next higher gear to see if the whine changes or remains the same.
If it remains, it probably isn't related to the engine but to some rotating part(s) outside it (for example, wheel bearings.)
If it changes, then the noise is coming from some engine component and alternators can do this when the amperage load is high; it's also a part that turns at a fairly high speed and will 'whine' rather than 'growl.'

Hi Pullerwife,
I have a few suggestions for you,
First of all, check your air filter, make sure its clean, not clogged, and doesn't need to be changed.
I don't know how handy you are, but if you are fairly handy, check the idler pulley bearings, if your not, have a shop check it out, as a last resort.
Power steering pump/fluid being low is also a possibility, but thats usually more of a lower pitched whine then what you describe.
You say once the vehicle is warmed up, the whining stops. Does Weather seem to be a factor as well?
Hope I've helped, and don't forget to rate.

Have the tranny serviced with fluid change and filter, if noise it still there it is the torque converter . Have the dealer fix it ,and have it on paper with dealer invoice when it is done. Do all this before warranty expires. IT IS NOT USUAL for any car, Toyota included, to have tranny whine!!!!!
