Depth:
Comprehensive, covering from basic maintenance to major component overhaul and electrical system diagnostics
Engine Families:
TU (e.g., TU3, TU5) and XU (e.g., XU7, XU9, XUD) series petrol and diesel engines
Power Output:
Varies significantly by engine: e.g., 1.1L (approx. 60 hp), 1.4L (approx. 75-90 hp), 1.6L (approx. 88-100 hp), 1.8L (approx. 103 hp), 1.9D (approx. 68 hp), 1.9 TD (approx. 70-92 hp), 2.0L (approx. 121-135 hp). Specific figures depend on engine code and tuning.
Torque:
Varies by engine and configuration. Manuals will provide specific figures for each engine variant.
Petrol Injection:
Single-point injection (SPI) and multi-point injection (MPI) systems, often Bosch or Lucas-based.
Diesel Injection:
Indirect injection (IDI) and direct injection (HDI - later models may feature this) systems, rotary or in-line pumps.
Fuel Type:
Unleaded gasoline (95 RON typically), Diesel
Oil Change:
Typically every 10,000-15,000 km or 12 months, depending on engine and driving conditions. Manual will specify.
Timing Belt:
Critical component. Typically replaced every 60,000-80,000 km or 4-5 years for petrol engines (XU and TU series). Diesel engines may have different intervals or timing chains for some variants. Always consult the manual.
Transmission Fluid:
Manual: Typically a long-life fluid, check level periodically, change if contaminated or at high mileage. Automatic: More frequent checks and changes, e.g., every 40,000-60,000 km.
Engine Oil:
Viscosity grades commonly used: SAE 5W-40, 10W-40, or 15W-50 depending on climate and engine. Specific API or ACEA specifications required (e.g., ACEA A3/B3 for synthetic/semi-synthetic). Manual is definitive.
Coolant:
Ethylene glycol-based antifreeze, mixed with demineralized water in a 50/50 ratio. Specific Citroën approved coolant (e.g., PSA 1612 C1) is recommended.
Brake Fluid:
DOT 3 or DOT 4 brake fluid. Must be replaced every 2 years due to hygroscopic properties.
Power Steering Fluid:
Specific hydraulic fluid (often LHM for older PSA systems, but ZX may use common power steering fluid like Pentosin or Dexron compatible). Manual check is essential.
Suspension:
Wear in rear axle bushes and suspension components, especially on models with Hydractive suspension. Spheres may require recharging or replacement.
Engine:
Timing belt failure if not replaced on schedule (catastrophic). Occasional injector issues, ECU problems on some variants, oil leaks from seals and gaskets.
Electrical:
Corrosion in wiring connectors, issues with central locking, window regulators, and dashboard warning lights are not uncommon due to age.
Bodywork:
Rust on sills, wheel arches, and door bottoms can be an issue, especially in regions with harsh winters.
Citroen Focus:
Citroën's history is marked by innovation in suspension systems, front-wheel drive, and aerodynamic design, all of which are present in the ZX.
Development:
The ZX was developed as a replacement for the ageing Citroën GSA and a more conventional hatchback alternative to the complex Citroën Visa. It was designed to be lightweight, fuel-efficient, and comfortable, featuring Citroën's characteristic innovative suspension.
Key Innovations:
Optional Hydractive suspension system, offering a blend of comfort and handling. Compact dimensions with a spacious interior.
Production Years:
1991-1998 (in Europe)
Manufacturing Locations:
Primarily France (Aulnay-sous-Bois plant)
