State the oil cooler quantity, vehicle application and agreed assembly contents. Identify pieces per set and any separately priced hardware before comparing quotations.
Nissan Sunny ยท Engine, Fuel, Cooling, Electrical & A/C
Match the Sunny oil cooler to engine or cvt fluid circuit. Record coolant and oil port layout; include core or housing assembly contents before sampling.

| 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 full chassis, body, production date, engine, transmission and sales market on the same record. The Sunny chassis and market 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.
Sunny Oil Filter โ Thread, seal and bypass specification must stay with the exact engine; a broad Nissan cross-reference is not universal Sunny proof. Check engine code and filter count; record thread and gasket dimensions on its own order line.
Sunny Transmission Filter โ An Xtronic CVT strainer is not identified by the word automatic, and manual gearboxes do not use the same service item. Check manual, automatic or xtronic CVT code; record internal strainer neck and pickup position on its own order line.
Sunny Radiator โ Engine, CVT cooler connections, core size and fan package vary by generation and trim. Check engine, transmission and cooling package; record core dimensions and hose positions 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 Sunny parts directory for other systems.
For oil cooler requirements on other vehicles, compare the radiator and cooling directory. Keep the Sunny specification and every other approved model on separate order lines.
