So my car has recently developed a chirp..It only seems to occur first thing in morning or after sitting for 6 or so hours. It's coming from the Alternator/Tensioner area, can't tell which yet..The chirp goes away after the engine has been running a few minutes and doesn't return the rest of day if I'm using the car. Also, if I drive it cold while chirping the noise will increase or decrease with engine speed until it eventually " fades " when engine warms to normal temp. My first thought was a bearing in Alternator, but I'm thinking if that were the case it would do it all the time, same for tensioner...I haven't really inspected belt because it's fairly new. Any thoughts would be greatly appreciated...as it is a little annoying, especially at 6:30 in the morning...the chirp just echo's threw the land.
