Hey,
I just recently purchased a used 2003 Infiniti g35 coupe and have literally searched everywhere for a solution to my problem~~can't seem to find any kind of information on it. There is a loose bolt on my ac compressor~~and no matter how much I tighten it, it seems like the clutch plate it is holding keeps turning with the bolt not letting me screw the bolt in at all~~I found a maual where it states I need a clutch disc wrench~~which I don't have. I called Infiniti and they want 135 dollars just to diagnose the problem even if it is a simple bolt tighten~~that is just too much. I have some pics attached to show you the bolt.~~The ac is working fine but due to the loose bolt it is squealing like crazy~~

Any ideas on how to tighten this bolt without the special tool? Please reply asap. Thank you.

 

I don't know jack **** about the issue, but I do know that you can rent specialty tools from autozone or advance.

Now sure if they have what you need, but worth checking.

 

or take it to a mechanic and ask them to tighten it, doubt they'd charge you $130 to tighten a bolt! That bolt looks a little rusty too, so why not get a new one while you're at it too.

 

According to FSM, the A/C compressor uses a magnetic clutch. You should be able to unplug the harness and apply battery power directly to lock the clutch. It might allow you to tighten the bolt.
