Nissan Dayz B21W in Pakistan: CVT Service & Parts Identity

Nissan's archived Dayz specifications identify DBA-B21W and its CVT configurations. Confirm the production period, turbo or non-turbo equipment and 2WD/4WD record before a parts order. Do not transfer references from the later B4xW generation or assume a visually similar Mitsubishi-branded vehicle proves interchangeability.

The official FAQ separates the June 2013 launch, February 2015 coolant-brand change and December 2015 oil-specification change sections. Its CVT rows specify genuine Nissan CVT Fluid NS-3 and warn that another oil can damage the CVT. Read the correct section and drivetrain row rather than flattening every fluid and axle reference into one model-wide answer.

Nissan lists approximately 6.0 L for the CVT in the cited FAQ. That is not evidence that a routine service drains that amount, nor permission to add that quantity. Ask the workshop for the correct operation, quantity basis and manufacturer procedure. Do not request an undocumented universal flush because the service menu has one price for all CVTs.

The fluid FAQ does not establish an OEM strainer, gasket, battery or ignition-part number. Ask the supplier for written confirmation of each exact product against the chassis, equipment and period, and identify any supersession. A stop-start or battery-assist description does not make this car equivalent to Nissan's HE12 e-POWER architecture.

Record warning messages, the driving conditions, previous work and odometer history. Ask what findings support the proposed component, what work is included, and what warranty or return terms apply. A symptom does not prove a failed CVT or justify an assembly replacement. Keep the JDM documentation with the Pakistan service invoice; no local price or factory-specification claim is made here.
