Hey guys im new at this page .. Prob there is a post with this info but if not then i just need the size of drive belt and ac belt how many ribs since in autozone cant give me the right size if anyone know .. Share it plz i will apreciate it thank you.

 

Look at the belts that are on there now. If they aren't like 10 years old and faded/worn, you should be able to just read the numbers off of them and get the equivalent version stocked at your local Auto Zone or other auto parts store.

I believe all the G's use a 6-rib belt though. The length depends on what year you have... probably the same belt from 03-06 and maybe a different one henceforth. You'd need to give us more info about your car.

If you are just replacing factory belts though on an 03-06 G, you should remove the extra idler pulley on the front of the car and replace it with a 1" shorter than stock belt. It's a sweet "free"mod basically. All you have to do is either buy the small aluminum washer/spacer from Nissan, or order the kit from Z1 Motorsports (which comes with both a factory Nissan shorter-version belt as well as the spacer), remove the idler pulley assembly and replace it with the spacer and then install the new/smaller belt. The idler pulley delete saves you about 2 pounds of rotational mass on the engine and you'll never have to worry about that idler pulley wearing out and snapping your serpentine belt.

 

Well its coupe 2003 with 120k miles not sure if they ever changed it .. But the way i found it i doubt they ever did so havent check it yet.. But i will do that thank you so much!!
