⚙️ Engine Specifications

Engine Displacement:

Likely 1.6L or 1.9L gasoline engines for the 1984 model year. Specific engine codes (e.g., XY7, XU5, XU9) would be detailed within the manual.

Horsepower Range:

Varies by engine, typically between 70-100 hp for naturally aspirated gasoline variants. Diesel options also existed but less common for early US imports if any.

Torque Range:

Varies by engine, typically in the range of 110-150 Nm.

Fuel System Type:

Primarily carbureted for 1.6L engines, with early Bosch L-Jetronic or similar fuel injection systems potentially available on higher-spec 1.9L models.

Ignition Type:

Distributor-based electronic ignition.

Engine Codes Covered:

The manual will detail specific engine codes like XY7 (1.6L) and XU5/XU9 (1.9L) families, including their variations.

🔧 Transmission

Standard Transmission Type:

4-speed or 5-speed manual transaxle.

Optional Transmission Type:

3-speed or 4-speed ZF automatic transaxle.

Clutch Type:

Single dry plate, hydraulically operated.

Manual Transmission Fluid:

Likely GL-4 specification manual transmission fluid, e.g., SAE 75W-90 or 80W-90. Capacity typically around 2.0-2.5 liters.

Automatic Transmission Fluid:

Dexron II or equivalent ATF. Capacity typically around 3.5-4.5 liters.

📐 Dimensions

Hydropneumatic Fluid:

Citroën LHM (Low Hydro-mechanical fluid), or equivalent LHS 2 (for later models, but LHM is likely for '84). Critical to use the correct fluid to avoid system damage. Capacity varies but system charge is important.

Common Issues Bx:

Hydropneumatic suspension leaks (spheres, hoses, seals), rust on bodywork (particularly sills, wheel arches), electrical gremlins (especially older wiring), carburetor or fuel injection issues, wear in suspension bushings, aging plastic components.

Repair Difficulty Hydropneumatic Suspension:

Requires specialized knowledge and tools due to the high-pressure hydraulic system. This manual is essential for proper diagnosis and repair.
