The Ford T7DA is a 1,596 cc, inline‑four naturally aspirated petrol engine produced between 2005 and 2011. It features a dual overhead camshaft (DOHC) layout with 16 valves and sequential multi‑point fuel injection. In standard form it delivered 80 kW (109 PS) and 150 Nm of torque, balancing urban responsiveness with highway refinement.
Fitted to compact and entry — level models such as the Mk5 Fiesta, Mk2 Fusion, and C‑Max, the T7DA was engineered for everyday drivabilit…
All production years 2005–2011 meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/9352).
The Ford T7DA is a 1,596 cc inline‑four naturally aspirated petrol engine engineered for compact and MPV applications (2005–2011). It combines DOHC architecture with sequential multi‑point fuel injection to deliver linear power delivery and responsive throttle behavior. Designed to meet Euro 4 emissions standards, it emphasizes serviceability and fuel efficiency for high-mileage urban use.

The Ford T7DA was used across Ford's Mk5 Fiesta, Mk2 Fusion, and C-Max platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—revised intake manifolds in the C-Max and unique engine mounts in the Fiesta—and from 2008 the updated camshaft improved reliability, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
The T7DA's primary reliability risk is intake camshaft lobe wear on early builds, with elevated incidence in high-mileage or cold-climate vehicles. Ford internal data from 2009 indicated a notable share of pre-2008 engines required camshaft replacement before 120,000 km, while UK DVSA records show related misfire codes as a recurring MOT advisory item. Infrequent oil changes and use of non-spec oil increase wear risk, making correct oil specification and interval adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The T7DA offers smooth performance and good efficiency, but early models (2005–2007) are prone to camshaft lobe wear. Later revisions (2008–2011) improved cam durability. With regular oil changes using correct 5W-30 spec and timely ignition maintenance, the engine can reliably exceed 180,000 km.
Top issues include intake camshaft lobe wear, cam cover oil leaks, ignition coil pack failures, and cracked plastic thermostat housings. These are well-documented in Ford service bulletins, particularly SIB 08S14 for the camshaft system.
The T7DA 1.6L petrol was used in the Mk5 Fiesta (2005–2008), Mk2 Fusion (2005–2011), and Mk1 C-Max (2005–2010), all producing 109 PS. It was not licensed to other manufacturers and is distinct from the Duratec Ti-VCT and earlier Zetec engines.
Modest gains are possible. ECU remaps typically yield +8–12 kW safely, as the DOHC internals are robust for a naturally aspirated engine. Forced induction is not recommended without major upgrades. Most owners focus on throttle response and exhaust tuning for drivability improvements.
In a Fiesta 1.6i, expect ~8.5 L/100km (city) and ~5.6 L/100km (highway), or about 41 mpg UK combined. The C-Max achieves slightly lower figures due to higher weight—typically 38–42 mpg UK on mixed roads for a well-maintained T7DA.
Yes. The T7DA is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, causing catastrophic damage. Although chain failure is rare, any timing-related warning (e.g., rattles, codes) must be addressed immediately.
Ford specifies SAE 5W-30 oil meeting WSS-M2C913-C (or newer) standard. Always use a quality synthetic oil designed for DOHC petrol engines and change it every 10,000–15,000 km to protect cam lobes and prevent sludge buildup.
