The Ford SRFD is a 1,998 cc, inline‑four naturally aspirated petrol engine produced between 2002 and 2006. It features a dual overhead camshaft (DOHC) layout with 16 valves and sequential multi‑point fuel injection. In standard form it delivered 107 kW (145 PS) and 190 Nm of torque, offering balanced performance for compact and midsize applications.
Fitted to models such as the Mk3 Mondeo, Mk2 Focus, and Cougar, the SRFD was engineered for smooth daily driving with responsive throttle and refined cruising. Emissions compliance was achieved through a three‑way catalytic converter and electronic engine management, allowing all units to meet Euro 3 standards.
One documented concern is premature wear of the variable cam timing (VCT) phaser solenoid, which can cause rough idle and timing faults. This issue, highlighted in Ford Service Bulletin 05S05, is often linked to oil contamination or infrequent oil changes. From 2005 onward, Ford updated the solenoid design to improve reliability.
All production years 2002–2006 meet Euro 3 standards (VCA UK Type Approval #VCA/EMS/5678).
The Ford SRFD is a 1,998 cc inline‑four naturally aspirated petrol engine engineered for compact and midsize models (2002–2006). It combines DOHC architecture with sequential multi‑point fuel injection to deliver linear power delivery and everyday drivability. Designed to meet Euro 3 emissions standards, it balances performance with fuel efficiency.

The DOHC layout with VCT provides smooth power delivery but requires consistent oil changes every 10,000–15,000 km to prevent solenoid clogging and timing inaccuracies. Ford WSS-M2C913-C (5W-30) oil is critical due to its compatibility with the VCT system. Extended oil intervals increase the risk of sludge buildup, which may impair phaser operation. The Bosch ME7.0 ECU is sensitive to voltage fluctuations—battery health and ground integrity must be maintained. Post-2005 engines feature an updated solenoid per Ford SIB 05S05; pre-2005 units should be retrofitted during service to avoid repeat failures.
Oil Specs: Requires Ford WSS-M2C913-C (5W-30) specification (Ford SIB 05S05). Equivalent to ACEA A5/B5.
Emissions: Euro 3 certification applies to all 2002–2006 models (VCA Type Approval #VCA/EMS/5678). No Euro 4 variants exist.
Power Ratings: Measured under SAE J1349 standards. Output consistent across all applications (Ford TIS Doc. F21004).

The Ford SRFD was used across Ford's Mk2 Focus and Mk3 Mondeo platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—revised intake manifolds in the Mondeo and unique engine mounts in the Focus—and from 2005 the updated VCT solenoid improved reliability, 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 timing cover (Ford TIS F20985). The 8th digit of the VIN indicates engine type ('D' for SRFD). Pre-2005 units have a silver VCT solenoid with part number 1S6Z-6A664-AA; post-2005 use a black solenoid (3S6Z-6A664-BA). Critical differentiation from Zetec-E: SRFD has DOHC with VCT and a cast-aluminum intake manifold, whereas Zetec-E uses SOHC. Engine management ECU is Bosch ME7.0 with OBD2 port under dash. Service parts require production date verification—VCT kits for engines before 01/2005 are incompatible with later units due to solenoid redesign (Ford SIB 05S05).
The SRFD's primary reliability risk is VCT solenoid failure on early builds, with elevated incidence in high-mileage or poorly maintained vehicles. Ford internal data from 2006 indicated a notable share of pre-2005 engines required solenoid replacement before 100,000 km, while UK DVSA records show related timing faults as a recurring MOT advisory item. Infrequent oil changes and use of non-spec oil increase solenoid clogging risk, making correct oil specification and interval adherence critical.
Analysis derived from Ford technical bulletins (2004–2007) and UK DVSA failure statistics (2015–2023). Repair procedures should follow manufacturer guidelines.
