Ford Focus / Connect / Fiesta 1.6tdci T1DB/TZJA/CV1Q engine
R32,500.00
The Ford 1.6 TDCi (T1DB, TZJA, and CV1Q) engine codes refer to a 1.6-litre, 4-cylinder turbocharged diesel engine from the Duratorq family (specifically the DV6C/DV6D series). These engines were co-developed with PSA Peugeot Citroën and are known for their exceptional fuel economy, often achieving under 4.0L/100km in certain models.
Engine Specifications & Variations
While these codes share the same core 1,560 cc architecture, they are tuned for different power outputs and vehicle applications.
| Engine Code | Typical Vehicle Application | Power Output | Torque | Emissions |
|---|---|---|---|---|
| T1DB | Ford Focus Mk3 | 85 kW (115 PS) | 270–285 Nm | Euro 5 |
| TZJA | Ford Fiesta / Transit Connect | 70 kW (95 PS) | 205–230 Nm | Euro 5 |
| CV1Q | Fiesta / Transit Connect | 70 kW (95 PS) | 230 Nm | Euro 5 |
Key Design Features
- 8-Valve SOHC: Unlike earlier 1.6 TDCi versions (which were 16-valve), these later Euro 5 versions (DV6C/DV6D) moved to an 8-valve Single Overhead Camshaft (SOHC) design to improve reliability and reduce internal friction.
- Fuel System: Utilises a high-pressure Common Rail Direct Injection system (often Bosch or Continental), which allows for precise fuel delivery and lower emissions.
- Construction: Features an aluminium block and cylinder head for weight reduction.
- Interchangeability: The “bare” engines are often physically identical across these codes; however, external components like the sump, dipstick tube, and wiring loom may differ depending on the vehicle.
Common Issues & Maintenance
- Injector Seals: A notorious issue where the copper seals fail, causing fuel/carbon leakage (often called “the black death”) around the injectors.
- Turbocharger Longevity: Turbo failure is common if oil changes are neglected. Carbon buildup can clog the narrow oil feed pipes, starving the turbo of lubrication.
- Timing Belt: Driven by a timing belt (cambelt) with a recommended replacement interval of approximately 10 years or 180,000–200,000 km, though specialists often suggest earlier intervals (e.g., 120,000 km).
- DPF & EGR: Like most modern diesels, short city trips can lead to clogged Diesel Particulate Filters (DPF) and EGR valves.
