What to quote
State the alternator quantity, vehicle application and agreed assembly contents. Identify pieces per set and any separately priced hardware before comparing quotations.
Nissan Sentra · Engine, Fuel, Cooling, Electrical & A/C
Specify Sentra alternator by engine and charging specification. Retain output, connector and regulation and pulley and mounting geometry so offers describe the same assembly.

| Record | Details to retain |
|---|---|
| Engine and charging specification | Identify engine and charging specification from the vehicle, installed assembly or readable label. |
| Output, connector and regulation | Show output, connector and regulation in photographs and retain measurements that distinguish the interfaces. |
| Pulley and mounting geometry | Specify pulley and mounting geometry together with every piece required in the quoted assembly. |
Output, pulley and charging control can differ by engine and production market.
For this alternator, keep chassis, production date, engine, transmission and sales market on the same record. The Sentra B13–B18 identification guide explains why a regional name alone is insufficient.
When this component is part of a mixed system order, use the fuel, cooling, electrical and a/c to separate neighboring assemblies.
Send overall and mounting or connection photographs. For the alternator, retain output, connector and regulation and pulley and mounting geometry; mark unknown values instead of borrowing a number from another generation. Use the OE and vehicle-identification checklist to organize the evidence.
Give every linked assembly its own specification; approving the alternator does not confirm the surrounding parts.
Sentra Drive Belt — Accessory routing changes with engine and equipment; record the installed marking rather than ordering by model year alone. Confirm engine and accessories and belt marking and rib count on its own order line.
Sentra Belt Tensioner — Pulley-only and complete tensioner offers are not comparable, and offset can differ even with the same belt width. Confirm engine and tensioning type and pulley diameter and offset on its own order line.
Sentra Starter Motor — Pinion engagement, mounting and terminals must match both engine and transmission. Confirm engine, gearbox and voltage and pinion and mounting flange on its own order line.
State the alternator quantity, vehicle application and agreed assembly contents. Identify pieces per set and any separately priced hardware before comparing quotations.
Protect pulley grooves, connectors and exposed terminals.
Before approving the alternator, agree sample and inspection requirements using the quality-control checklist. Return to the Sentra parts directory for other systems.
For alternator requirements on other vehicles, compare the alternator directory. Keep the Sentra specification and every other approved model on separate order lines.
