Buzzing Sound

[tshockey]

On a cold morning when starting the vehicle i can hear a distinct
buzzing sound on the left side of the engine,it lasts for about 2-to 3 seconds.Is this normal ? It is not everytime i start up but is really noticeable on cold mornings. THANKS

That's It!

That is the noise. I have the same problem. Do you hear it when you brake? Check my post http://www.toyota-4runner.org/showthread.php?s=&threadid=1401
