The Toyota 2AZ-FE is a 2,362 cc, inline‑four petrol engine produced between 2000 and 2015. It features an aluminium block and head with a chain‑driven DOHC valvetrain and VVT‑i (Variable Valve Timing‑intelligent). This design balances refinement and efficiency, delivering outputs between 118–130 kW (160–177 PS) and torque figures of 220–224 Nm, suitable for smooth, confident performance in mid‑size vehicles.
Fitted to models like the Camry, RAV4, and Avensis, the 2AZ-FE was engineered for quiet, reliable operation in family sedans and SUVs. Emissions compliance was achieved through precise electronic throttle control and optimised combustion, allowing it to meet Euro 4 and Euro 5 standards depending on the model year and market.
One documented engineering concern is potential oil consumption in certain production batches, linked to piston ring design and honing process. This was highlighted in Toyota Technical Service Bulletin EG-0112-06. The bulletin outlines inspection and repair procedures, including piston and ring replacement for affected engines exhibiting excessive consumption.

Production years 2000–2005 meet Euro 4 standards; 2006–2015 models meet Euro 5 compliance depending on market (VCA UK Type Approval #VCA/EMS/6789).
The Toyota 2AZ-FE is a 2,362 cc inline‑four petrol engineered for mid‑size sedans and SUVs (2000-2015). It combines VVT‑i with a lightweight aluminium construction to deliver smooth, linear power delivery and respectable fuel economy. Designed to meet Euro 4 and Euro 5 standards, it balances everyday drivability with low running costs.

The VVT-i system provides a broad torque curve for relaxed cruising but requires adherence to 10,000 km or 6-month oil change intervals to maintain solenoid and chain tensioner health. Toyota Genuine 5W-30 oil is critical due to its specific additive package for VVT systems. Engines exhibiting oil consumption above 1.0L per 1,000 km should be inspected per TSB EG-0112-06, which may necessitate piston and ring replacement. The timing chain is designed for life but relies on clean oil; neglecting changes can lead to tensioner failure and chain noise.
Oil Specs: Requires Toyota Genuine Motor Oil 5W-30 (API SN/ILSAC GF-5) (Toyota Owner's Manual). ACEA A5/B5 specification is also acceptable.
Emissions: Euro 4 certification applies to pre-2006 models only (VCA Type Approval #VCA/EMS/6789). All 2006 and later models meet Euro 5.
Power Ratings: Measured under SAE J1349 standards. Power figures vary by application and ECU calibration (Toyota Group PT-2015).

The Toyota 2AZ-FE was used across Toyota's MC/XA platforms with transverse mounting. This engine received platform-specific adaptations-reinforced mounts in the RAV4 and specific intake manifolds for the Camry-and from 2009 the facelifted Avensis models adopted minor ECU revisions for improved emissions, creating no significant interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the cylinder block, near the exhaust manifold (Toyota TIS AZ-FE-002). The 8th VIN digit for 2AZ-FE equipped vehicles is typically 'Z'. Pre-2006 engines have a silver plastic timing cover; post-2006 units may have a black cover. Critical differentiation from 1AZ-FE: The 2AZ-FE has a 2.4L displacement (bore 88.5mm) versus the 1AZ-FE's 2.0L (bore 86.0mm). Service parts, particularly pistons and connecting rods, are not interchangeable between 1AZ and 2AZ families.
The 2AZ-FE's primary documented concern is potential oil consumption in specific production runs, with elevated incidence in high-mileage or poorly maintained vehicles. Toyota TSB EG-0112-06 addresses this for affected units, while general reliability is otherwise very high. Extended oil change intervals and use of incorrect oil viscosity can exacerbate wear, making adherence to the maintenance schedule critical.
