Hey all, compressor died on me a couple of weeks ago in my 2011 Maxima, and the bearing is wearing more and more and starting to wobble the pulley to the point where the current belt is getting damaged. I'm having trouble finding info on the correct part number to chase down for a bypass belt for this model year, does anyone have any suggestions?

why would you not want AC? you racing?
typically there are pulley clutch kits for the AC compressor pulley.
and get a new belt.

I would love AC, just dont have the money to invest in fixing the compressor at the moment.

Well, not sure your budget.
Curious as to why you have to do a bypass?
Does the Compressor come on? Ez test, just fill with one can to see if it will engage. Leak points are fairly typical for car AC systems.
You can rent vacuum pump for evacuating system moisture.
Compressor and evaporator should not cost more than 300 all in? I want to venture guess Compressor isn't bad and you just have large leak somewhere?

sorry for digging up this thread... but I need to bypass my AC Compressor for a month or two... does anyone have an actual belt size/number?? Can't really afford a new compressor for at least a few weeks.. and this is my daily. Don't really want to end up on the side of the road with my two toddlers in the back looking for bolts because my compressor blew up. yes it squeals loudly. Thanks in Advance.

If belt is squeaky, change out the belt. Don't need to buy belt of a diff't size just to bypass. If you are thinking it's the pulley... Well, don't think, try to diagnose it. Your variables are limited as to belt squeaks. I had idlers pulleys squeaking in mine. So what I'm saying is don't guess at the Compressor being bad. One can of freon can tell you if the Compressor is working or not. And you should be able to tell at that time if it really is the Compressor pulley squeaking or not.

Just completed this project. I used a 540k6 belt. It'd 6 rib not 7, but works fine. I also replaced the upper idler pulley with a factory tensioner pulley because it is a little smaller. You need a little extra clearance if the belt isn't going around the ac. Hope this helps someone!
BTW, this rib belt is fine because all you are actually spinning is the power steering pump and the alternator. The water pump is gear driving inside the timing chain cover. I would not recommend using a 6 rib belt if the ac comprescompresser was hooked up. The factory belt is 67 inches
