Reconditioned Nissan Engine on an exchange basis

Reconditioned Nissan engines are not ordered by engine capacity: the engine code is the only valid starting point

This is the reality of the Nissan range: a single 1.5 dCi exists in more than twenty-four distinct K9K codes, each corresponding to a precise technical variant — power output, emissions standard, injection architecture. Ordering a bare engine on the basis of '1.5 dCi' alone, without specifying the code stamped on the block, risks an incompatibility at the point of fitting.

K9K, M9R, M9T: three diesel families covering the bulk of the range

The K9K is fitted to compact models — Micra, Note, Juke, first-generation Qashqai, Pulsar — and spans from K9K 282 to K9K 896 depending on year and market. The M9R (2.0 dCi) takes over on the Qashqai, X-Trail and Primastar in configurations ranging from M9R721 to M9R833. The M9T (2.3 dCi) covers heavier commercial vehicles — NV400, Primastar, NV200, Cabstar — with codes running from M9T 680 to M9T 890, plus the YS23DDTT for certain twin-turbo versions of the Navara. Alongside these three families, the F9Q (1.9 dCi) lives on in earlier generations of the Primastar and X-Trail, under codes F9Q-670 to F9Q-774.

Vans and 4x4s: specific blocks not to be confused with the passenger car range

The Navara and King Cab use the 2.5 dCi (codes G9U-750, G9U720, YD25DDTI), the Patrol the 3.0 dCi ZD30DDTI and the 2.8 TD RD28T — engines that are mechanically unrelated to those in passenger models, even where the engine capacity appears similar. On the petrol side, the DIG-T 1.2 (HR12DDT, HRA2DDT) and 1.3 (HR13DDT) are fitted to the Juke, Micra and recent Qashqai: two clearly distinct generations that are not interchangeable. For every order, the engine code — visible on the block or in the vehicle's technical documentation — remains the only reliable reference, regardless of the engine type.
