I have 20,000 on my 3800 v6 2002 camaro and the whole time I'm driving I hear a whistle from under the hood (sounds like a police car whizzing by) I just got the car... Sounds nice just checking to see if that's normal. Also, what is the recommended alternator size for my car? It seems a bit small for a fully loaded camaro and when I start it , the battery reader is at about half until it "Kicks in"??? then it goes beyond 3/4 of the guage. Does anyone else have this problem? Also when I hit the brakes, the battery guage needle goes down and the lights dim, then it returns to normal...but it doesn't happen all the time... thanks

 

Found out it wasn't the alternator just a loose connection
whewwwwwwwww

 

glad we could help, welcome to the V6 world

 

i was going to say, i think i had the same problem in my oldsmobile when i ran the RCA cables too close to the power cable for the amp. and then again, when my ground game loose, it seemed to whistle a little extra. glad you got it solved.

It is actually not the radio whistling it is under the hood.. when the radio is not even on plus it is a stock radio... that one is still a mystery but the power surge problem is addressed.....thanks
