The Nissan CR12DE is a 1,240 cc, inline‑three naturally aspirated petrol engine produced between 2002 and 2010. It features an aluminum block and head, dual overhead camshafts (DOHC), and 12 valves with multi-point fuel injection. This compact engine was engineered for efficiency and low emissions in Nissan's city car segment.
Fitted primarily to the Nissan Micra (K12) and Nissan Cube (Z11), the CR12DE was designed for urban agility and fuel economy. It offered adequate power for its lightweight applications, prioritizing smooth, quiet operation and low running costs. Emissions compliance for its production period was met through precise electronic fuel injection and a close-coupled catalytic converter.
One documented concern is premature wear of the timing chain tensioner, which can lead to chain rattle and potential failure if neglected. This issue, referenced in Nissan's internal service documentation, is often linked to extended oil change intervals. The design was eventually superseded by more advanced variants like the HR12DE.
Production years 2002–2010 meet applicable Japanese and European emissions standards for their respective model years (VCA UK Type Approval data for imported models).
The Nissan CR12DE is a 1,240 cc inline‑three naturally aspirated petrol engine engineered for compact city cars (2002-2010). It combines a lightweight aluminum construction with DOHC valvetrain and multi-point fuel injection to deliver smooth, economical performance. Designed to meet the emissions standards of its era, it prioritizes low-end torque for city driving and ease of maintenance.

The DOHC design provides a smooth, linear power curve ideal for city driving but requires diligent 10,000-15,000 km oil changes to prevent timing chain tensioner wear. Using the specified SAE 5W-30 oil is critical for maintaining hydraulic tensioner function. The MPI system is generally robust but requires periodic injector cleaning to maintain optimal fuel economy. Spark plugs should be replaced every 60,000 km as per Nissan Service Manual SM-CR12-05. The engine is non-interference, providing a safety margin if the timing chain fails.
Oil Specs: Requires SAE 5W-30 synthetic or semi-synthetic oil (Nissan Service Manual SM-CR12-05). This viscosity is essential for the hydraulic timing chain tensioner.
Emissions: Euro 4 certification applies to models produced from 2005 onwards (VCA Type Approval data for UK imports). Pre-2005 models meet pre-Euro standards.
Power Ratings: Measured under JIS D 1001 standards. Output varies slightly by model application and market (Nissan Group PT-2008).

The Nissan CR12DE was used across Nissan's K12/Z11 platforms with transverse mounting. This engine received platform-specific adaptations-revised engine mounts for the Z11 Cube and different accessory brackets for the K12 Micra-creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the cylinder block, near the alternator (Nissan Service Manual SM-CR12-05). The 8th VIN digit typically indicates engine type ('C' for CR12DE in many markets). Visually, it is identified by its three-cylinder configuration and the "CR12" casting on the cam cover. Critical differentiation from HR12DE: CR12DE has a conventional timing chain, while HR12DE uses a timing chain with a different tensioner design and revised cylinder head. Engine mounts are not interchangeable between K12 and Z11 applications.
The CR12DE's primary reliability risk is timing chain tensioner wear, with elevated incidence in high-mileage engines or those with poor maintenance. Nissan workshop data indicates this is a frequent cause of engine noise and potential failure in neglected engines, while owner reports often cite minor oil leaks as a secondary concern. Infrequent oil changes make adherence to the factory service schedule critical.
