Do you guys have any thoughts why my GS3 has a whiney/whistling sound whenever i start it up in the morning? It goes away though after 30 secs. Does anyone else have this problem? What is it? thanks.

could be your serp belt.

Definitely sounds like the serpentine belt. I had to replace mine at 60k miles.

Thanks guys. You are the greatest.

Could somebody confirm that the serpentine belt is a v-ribbed drive belt located in the front of the engine with adjustable tensioners? thanks.

the pretensioner is not adjustable... its actually spring loaded

Mine's doing the same thing. Started about 45k miles, now at 65k

Some silicone spray once in a while keeps down the squeaks...but I really should buy a belt.

well its not good to use that belt dressing spray stuff. there is actually two problems when u have the belt squealing:

1- belt is getting old and it squealing because its slipping
2- belt is loose/misaligned because the tensioner pulley is going out and you'll need to replace it

EDIT: granted the pulleys might need a little lube once and awhile but if u find urself spray belt dressing and lubing the pulleys all the time its more than likely the belt or tensioner pully

sounds like your waterpump needs to be replaced like mines.

Oksy, one more time...Could somebody confirm that the serpentine belt is a v-ribbed drive belt located in the front of the engine? Sorry for the confusion of the first post thanks.

not sure what u mean by v-ribbed but heres a diagram for the removal of the serpentine belt on a gs300. its the only belt you see without removing any covers, the timing belt is behind the engine cover.
