Check your belt tensioner pulleys. When the bearings are shot they give a high pitched whine.


From my experience at least

Howzit

Could be any of the rotating elements. Also suspect alternator. Remove the cooling duct, stick one end of a hose pipe inside there and the other endin your ear. It it's real loud then that is the culprit.

You can use this method to track the source. just watch your fingers near the fan and pulleys.

Alternator rebuild is about R450 for only the bearings. Otherwise about R1200 for complete rebuild.

A way to check the tensioner pulley is to give it a squirt of Q20. That quietens it, but not for long.
