Anyone know the size of the bolt for the idler pulley under ther a/c compressor??? I need to know the depth and size.... Long story short, it hasn't been there, and I've been running my a/c and when im at an idle or low rpm's you hear the viberation from the belt where it has the gap between the two pulleys being amplifed by the alternator.... So if anyone knows what size that is, cause I really don't wanna have to buy the pulley and bolt from the dealer as its 46 bucks, and the pulley (which I already bought from autozone) is only 20.

 

Cant you just get the bolts from the dealer, and get the pully from autozone?

 

Sorry for the delay in the response, but that is what I asked the dealer in the first place and he said, no it is all one item....

 

I know this is an old thread but maybe someone is watching----I wish to remove the compressor and run a belt over an idler pulley mounted in the hole beneath where the compressor was---I know the belt and idler part numbers but have heard (you Tube) that I will need the spacer behind the pulley---- anyone know the spacer part number?or any thing to help? 96 Blazer 4.3l.........THANKS
