Nissan Sentra · Filters, Ignition & Transmission Service
For Sentra belt tensioner, start with engine and tensioning type; use pulley diameter and offset and bracket and assembly contents to separate similar variants.

| Record | Details to retain |
|---|---|
| Engine and tensioning type | Identify engine and tensioning type from the vehicle, installed assembly or readable label. |
| Pulley diameter and offset | Show pulley diameter and offset in photographs and retain measurements that distinguish the interfaces. |
| Bracket and assembly contents | Specify bracket and assembly contents together with every piece required in the quoted assembly. |
Pulley-only and complete tensioner offers are not comparable, and offset can differ even with the same belt width.
For this belt tensioner, 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 service, ignition and cvt packs to separate neighboring assemblies.
Send overall and mounting or connection photographs. For the belt tensioner, retain pulley diameter and offset and bracket and assembly contents; 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 belt tensioner 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 Alternator — Output, pulley and charging control can differ by engine and production market. Confirm engine and charging specification and output, connector and regulation on its own order line.
Sentra Air Filter — B16, B17 and B18 airboxes do not share one element; engine size alone is not enough without the housing outline. Confirm engine and airbox family and element outline and dimensions on its own order line.
Sentra Oil Filter — Thread, seal and bypass specification must stay with the exact engine; a broad Nissan cross-reference is not universal Sentra proof. Confirm engine code and filter count and thread and gasket dimensions on its own order line.
State the belt tensioner quantity, vehicle application and agreed assembly contents. Identify pieces per set and any separately priced hardware before comparing quotations.
Protect the pulley bearing and restrain the arm for transport.
Before approving the belt tensioner, agree sample and inspection requirements using the quality-control checklist. Return to the Sentra parts directory for other systems.
