Q: Anyone have a acurate duagram for a 1993 nissan altima gxe serpentine belt placement ?

Your vehicle use a two belt system as depicted in this diagram. If you desire, a mechanic dispatched by YourMechanic can re-install the belt and, as is required during any belt replacement, inspect all of the rolling elements driven by the belt for smooth operation. Typically, the grease in the pulleys dries out and the belt pulleys make noise or run roughly after operating for 100,000 miles or more. If you desire inspection and installation just use the aforementioned service link and the responding certified mechanic will take care of everything. If you have further questions or concerns, do not hesitate to re-contact YourMechanic because we want you to make the most of your repair dollars and help you to get the best possible results.
