Engine Whine

[Sloth_n@med_Speed]

Need help.
Recently been hearing a whining noise coming from the car. Only happens when the car is coasting/idling, and sounds like a vacuum cleaner. Noise stops when under power, and starts back up after coming off the accelerator. Also seems to stop when the cooloing fans turn on. Had a quick look and it sounds like its the alternator/brake booster, but also read that it might be the idler pulley. Looking to get the problem fixed, but don't have the money to buy parts that don't need replacing.

Idlers pulleys are the most likely. They are cheap and fairly easy to do yourself.

If it's alternator, that can cost a bit to get someone to do because they may just replace it with a new one.
A reconditioned alternator can be cheaper way to go.
Cheaper still is to get one of the correct amperage from a wrecker.

Power steering can sound like that when the pumps are worn. (Top passenger side)

Water pump can also sound like that as the bearing craps out. (bottom centre)

Maybe see if someone can increase revs for you as you have a look under the bonnet to narrow down the location.

yeah will have to get the missus to help out. But that helps heaps. The car has about 300k on it, so nothing surprising, but don't have the money to do everything at the moment.
