The Ford T7CN is a 1,596 cc, inline‑four naturally aspirated petrol engine produced between 2002 and 2008. It features a single overhead camshaft (SOHC) layout, 16‑valve architecture, and sequential multi‑point fuel injection. In standard form it delivered 74 kW (101 PS) at 5,800 rpm and 145 Nm of torque at 4,000 rpm, offering balanced urban and highway performance with modest fuel consumption.
Fitted primarily to the European — market Ford Focus Mk1 facelift and Fiesta…
All production years (2002–2008) meet Euro 3 emissions standards .
The Ford T7CN is a 1,596 cc inline‑four naturally aspirated petrol engine engineered for compact models (2002–2008). It combines SOHC 16‑valve architecture with sequential multi‑point fuel injection to deliver responsive low-to-mid range performance and everyday drivability. Designed to meet Euro 3 emissions standards, it balances simplicity with urban efficiency.

The Ford T7CN was used across Ford's C‑platform derivatives with transverse mounting and no external licensing. This engine received platform-specific adaptations—revised engine mounts in the Focus and modified intake manifolds for packaging in the Fiesta—creating minor service part distinctions. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from manufacturer technical service bulletins and industry workshop records. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The T7CN is generally reliable if maintained properly, but early models (2002–2004) are prone to cam lobe and tappet wear. Later revisions improved durability. Regular oil changes with correct 5W-30 spec oil and timely timing belt replacement are essential. With care, it can exceed 150,000 km without major issues.
Top issues include cam lobe/tappet wear, timing belt failure (due to missed service), throttle body carbon buildup, and ignition coil pack degradation. These are documented in Ford service bulletins like 04S09 and widely observed in field data.
The T7CN was used in the Ford Focus Mk1 facelift (2002–2004) and the Ford Fiesta Mk5 (2002–2008), both in 1.6-litre form. No other Ford or partner brands used this engine.
Modest gains are possible via ECU remap (+5–8 kW) and induction/exhaust upgrades, but the SOHC 16-valve design limits airflow. Aggressive tuning is not recommended due to marginal cam durability. Focus on maintenance for longevity rather than performance.
In the Focus or Fiesta, expect ~7.0 L/100km (city) and ~5.0 L/100km (highway), or about 40–48 mpg UK combined. Real-world economy depends on driving style and vehicle weight.
Yes. The T7CN is an interference engine. If the timing belt fails, piston-to-valve contact can cause severe internal damage. This makes strict adherence to the 100,000 km or 6-year replacement interval critical.
Ford specifies SAE 5W-30 oil meeting WSS-M2C913-C (or newer). This ensures proper cam and tappet protection and sludge control. Change every 10,000 km or 12 months, whichever comes first.
