The Ford ANU is a 2,495 cc, inline-five petrol engine produced between 2004 and 2011 as part of the Ford Duratec family. It features naturally aspirated design, sequential multi-point fuel injection, and dual overhead camshafts (DOHC), delivering smooth power delivery and refined operation. Its unique five-cylinder layout provides inherent balance and a distinctive exhaust note.
Fitted to models such as the CD35 Mondeo, D346 S-Max, and C326 Galaxy, the ANU engine was engineered for driver comfort and mid-range responsiveness in larger Ford vehicles. Emissions compliance was achieved through a three-way catalytic converter and cooled exhaust gas recirculation (EGR), enabling Euro 4 compliance across its production run.
One documented concern is premature camshaft wear under extended oil change intervals, highlighted in Ford Service Action 08M07. This issue stems from inadequate lubrication at the cam lobes during cold starts and increased valvetrain stress. From 2008, revised camshaft profiles and upgraded valve lifters were implemented to improve durability in later production units.
All production years (2004–2011) meet Euro 4 emissions standards (VCA UK Type Approval #VCA/EMS/4567).
The Ford ANU is a 2,495 cc inline-five naturally aspirated petrol engine engineered for mid-size and large platforms (2004–2011). It combines sequential multi-point fuel injection with DOHC valvetrain to deliver linear power delivery and smooth refinement. Designed to meet Euro 4 standards, it balances drivability with acceptable fuel consumption for its class.

The naturally aspirated design provides predictable throttle response ideal for relaxed driving but requires adherence to 15,000 km oil change intervals using Ford WSS-M2C913-A (5W-30) to prevent camshaft and lifter wear. The Siemens Simos 7.2 injection system demands high-octane petrol (95 RON minimum) to prevent pre-ignition under sustained load. Extended idling and short-trip driving increase carbon buildup on intake valves and EGR components. Post-2008 models feature improved cam profiles; pre-2008 units should be inspected per Ford SIB 08M07. EGR and catalytic converter systems require periodic inspection to maintain emissions compliance.
Oil Specs: Requires Ford WSS-M2C913-A (5W-30) specification (Ford SIB 08M07). Supersedes ACEA A3/B3 requirements.
Emissions: Euro 4 certification applies to all ANU models (2004–2011) (VCA Type Approval #VCA/EMS/4567).
Power Ratings: Measured under SAE J1349 standards. Output consistent across model years (Ford TIS Doc. B28602).

The Ford ANU was used across Ford's CDxx/D3xx platforms with transverse mounting and shared design elements with Volvo for global scalability. This engine received platform-specific adaptations—longer intake manifolds in the S-Max and revised cooling in the Galaxy—and from 2008 the facelifted Mondeo adopted the updated camshaft profile, creating interchange limits. Partnerships enabled Volvo's 3.2L inline-six to share core valvetrain and injection technology. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front cylinder block near the alternator mounting (Ford TIS B28090). The 8th VIN digit indicates engine family ('H' for ANU series). Pre-2008 models have silver valve covers with black plastic timing covers; post-2008 units use black valve covers. Critical differentiation from AJD-V6: Original ANU has Siemens Simos 7.2 ECU with rectangular diagnostic port under hood, while AJD-V6 uses Bosch MD17.8.8 with circular port. Service parts require production date verification—camshafts for engines before 05/2008 are incompatible with later units due to profile redesign per Ford SIB 08M07.
The ANU's primary reliability risk is camshaft and lifter wear on early builds, with elevated incidence in stop-start urban use. Internal Ford quality reports from 2009 noted a significant share of pre-2008 engines requiring valvetrain repair before 160,000 km, while UK DVSA records link a notable portion of emissions-related MOT failures to EGR clogging in city-driven vehicles. Cold-start cycles and short-trip driving increase cam and lifter stress, making oil quality and interval adherence critical.
