Depth Of Information:
Comprehensive, suitable for professional technicians and advanced DIY enthusiasts. Covers detailed disassembly, reassembly, specifications, and troubleshooting.
Engine Options Covered:
Likely covers the range of engines offered in the BX during the specified years, including 1.3L, 1.4L, 1.5L, 1.6L, 1.9L petrol engines, and potential diesel variants (e.g., XUD).
Horsepower And Torque:
Detailed specifications for each engine variant, including power output (HP/kW) and torque (Nm/lb-ft) at specific RPM ranges.
Fuel Delivery:
Covers both carbureted (e.g., Weber, Solex) and fuel-injected (e.g., Bosch LE2-Jetronic, K-Jetronic on some later models) fuel systems.
Ignition And Emissions:
Details on ignition systems (points, electronic), timing, fuel mixture control, and emission control systems relevant to the production years.
Gearbox Options:
Likely covers manual transmissions (e.g., 4-speed, 5-speed) and Citroën's semi-automatic (Citroën Automatic - often a clutchless manual) and potentially conventional automatic transmissions offered.
Transmission Service:
Procedures for clutch operation, gear selection mechanisms, and automatic transmission servicing (if applicable).
Braking System:
Front ventilated discs, rear drums. Details on hydraulic circuits, LHM fluid (for hydropneumatic models), brake booster operation, and ABS (on later models).
Body Structure:
Details on the BX's unique construction, including its plastic boot lid and generally rust-resistant galvanized steel body panels. Safety structures and impact zones.
Oil Change Interval:
Typically every 7,500 to 10,000 miles (12,000 to 15,000 km) or 12 months, depending on driving conditions and engine type.
Timing Belt Replacement:
Crucial for many BX engines (e.g., XU series). Intervals vary, but commonly around 60,000-80,000 miles (100,000-130,000 km) or 5-7 years. Manual will specify exact interval and procedure.
Hydraulic Fluid:
Citroën LHM Plus (Green mineral oil) is critical for the hydropneumatic suspension system. Manual will specify correct type and replacement intervals.
Engine Oil:
Viscosity grades will vary based on engine and climate (e.g., 10W-40, 15W-50, 20W-50). Manual specifies exact API/ACEA standards and capacities.
Coolant:
Ethylene glycol based antifreeze mixed with distilled water. Manual will specify the correct ratio and type.
Hydropneumatic System:
Potential for fluid leaks, failing spheres, worn hydraulic pump, or height corrector issues. Manual provides diagnostic and repair procedures.
Electrical Gremlins:
Common in older vehicles, especially minor issues related to wiring harnesses, switches, and connections. Manual's wiring diagrams are essential.
Rust:
While galvanized, certain areas like sills, wheel arches, and suspension components can be susceptible to corrosion. Manual may cover rust prevention and repair.
Exhaust System:
Corrosion and failure of exhaust components are common wear items. Manual details removal and replacement.
Citroen Innovation:
The BX represents Citroën's continuation of innovative design and engineering, particularly its advanced hydropneumatic suspension system which provided exceptional ride comfort and handling.
Bx Generations:
The BX was produced in two main series: Series 1 (1982-1987) and Series 2 (1987-1994), with styling and technical updates between them. The manual likely covers both.
Manufacturing Locations:
Primarily manufactured in France, but also assembled in other countries like the UK and Spain.
