Replacing the alternator and removing the belt and tensioner may have caused a problem with the a/c compressor and bearings , when you replaced the alternator did you replace the belt and tensioner if so it may have added enough pressue on the a/c bearings to cause the problem , if you didn't replace them it the a/c clutch bearing may be bad

I would look more towards the belt tensioner. Look at it when idling, Then when some one puts it in gear. If it is jumping, which they do. See if it is coinciding with the clicking.

A loud noise around the area of the timing belt cover at regular idle. Disappears when driving, then reappears when at idle again.


Dear SIr,
As you saying noise wont come in driving and only comes in idle , it means noise will not come if RPM is high by norma in idle l, try this one start the car don't drive it just raise RPM(rotation per minute of only engine not vehicle speed) in neutral gear , if noise disappear that mean it a problem of drive belt . If drive belt is got less tension then also it can occur or belt is damage, replace belt problem will solve, (for reference drive belt it drive alternator,powersteering pump,A/C compressor that is made by rubber).Thanks if any problem ask me.
Yogesh.

97 Lexus Es300 noise under the hood by alternator


mcdevito75 here, If you have 1 continuous belt on the engine (serpentine) then the belt could be worn or the tension pully holding the belt tight could be going bad. No noise in Neautral or Park as increased engine speed in these gears over rides the worn part and thus no noise. On a cold engine examine the belt, look for frays / wear from where the belt rides the pullys. If the belt is 2 years old, Change it.
