Nissan Sentra · Engine, Fuel, Cooling, Electrical & A/C
For Sentra oil cooler, start with engine or cvt fluid circuit; use coolant and oil port layout and core or housing assembly contents to separate similar variants.

| Record | Details to retain |
|---|---|
| Engine or CVT fluid circuit | Identify engine or CVT fluid circuit from the vehicle, installed assembly or readable label. |
| Coolant and oil port layout | Show coolant and oil port layout in photographs and retain measurements that distinguish the interfaces. |
| Core or housing assembly contents | Specify core or housing assembly contents together with every piece required in the quoted assembly. |
Confirm whether the unit serves engine oil or CVT fluid; similar cores cannot be exchanged across circuits.
For this oil cooler, 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 oil cooler, retain coolant and oil port layout and core or housing 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 oil cooler does not confirm the surrounding parts.
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.
Sentra Transmission Filter — A B17/B18 Xtronic CVT strainer is not identified by the word automatic, and manual gearboxes do not use the same service item. Confirm manual, automatic or xtronic CVT code and internal strainer neck and pickup position on its own order line.
Sentra Radiator — Engine, CVT cooler connections, core size and fan package vary by generation and trim. Confirm engine, transmission and cooling package and core dimensions and hose positions on its own order line.
Sentra Turbocharger — Restricted to factory B17 1.6T SR Turbo/NISMO applications; ordinary 1.8 and B18 2.0 cars are not turbo by default. Confirm b17 1.6t sr turbo/nismo engine and turbo label, flanges and ports on its own order line.
State the oil cooler quantity, vehicle application and agreed assembly contents. Identify pieces per set and any separately priced hardware before comparing quotations.
Cap each circuit separately and protect sealing faces.
Before approving the oil cooler, agree sample and inspection requirements using the quality-control checklist. Return to the Sentra parts directory for other systems.
For oil cooler requirements on other vehicles, compare the radiator and cooling directory. Keep the Sentra specification and every other approved model on separate order lines.
