Ignition system, fuel injection system (if applicable), emission controls.
Transmission:
Manual transmission (including specific Citroën transaxle design), clutch, drive shafts.
Hydropneumatic Suspension:
Detailed coverage of Citroën's unique hydropneumatic suspension system, including spheres, accumulators, hydraulic fluid, high-pressure circuits, self-leveling mechanisms, and height adjustment.
Braking System:
Front disc brakes, rear drum brakes, hydraulic system, parking brake, brake fluid specifications.
Steering System:
Steering rack, steering column, linkage.
Electrical System:
Wiring diagrams, battery, alternator, starter motor, lighting, instrumentation, fuses, relays, electronic components.
Body And Chassis:
Body panel repair, doors, windows, interior trim, underbody, rust prevention, structural components.
Comfort And Convenience:
HVAC (heating, ventilation, and air conditioning) system, power windows (if equipped), central locking (if equipped).
Maintenance:
Routine servicing, oil changes, filter replacements, fluid checks and top-ups, tune-ups, pre-delivery inspections (PDI).
Repair:
Step-by-step repair procedures for all major vehicle systems, including component disassembly, cleaning, inspection, repair, and reassembly.
Troubleshooting:
Diagnostic procedures, identification of common faults, and solutions for various mechanical and electrical issues.
Disassembly Assembly:
Detailed instructions for removing and reinstalling major components and sub-assemblies.
Specifications:
Critical torque values, clearances, fluid capacities, component dimensions, and other essential technical data.
Electrical Diagnostics:
Schematics, wiring diagrams, component testing, and troubleshooting guides for the electrical system.
Depth:
Comprehensive, covering everything from basic maintenance to major component overhauls, mirroring factory service manual content.
Engine Type:
Air-cooled, horizontally opposed four-cylinder boxer engine (Citroën 'Typ G' engine family).
Displacement Options:
Typically 1124cc (GS) and 1220cc (GS/GSA) for this era. Some markets may have had variants with slightly different displacements (e.g., 1299cc for later GSA variants).
Horsepower Range:
Approx. 56-75 hp (DIN) depending on engine displacement and tuning.
Torque Range:
Approx. 80-100 Nm depending on engine displacement.
Fuel Delivery:
Primarily single or twin-choke downdraft carburetors (e.g., Weber, Solex) for most 1984 models. Electronic fuel injection (EFI) became available on later GSA models, but the 1984 model is more likely to feature carburetors.
Oil Change Interval:
Typically every 5,000-7,500 km or 6-12 months (refer to specific manual for exact recommendation).
Major Service Interval:
Spark plug replacement, ignition timing adjustment, valve clearance adjustment typically recommended every 20,000-30,000 km.
Engine Oil Type:
Typically SAE 10W/40 or 20W/50 API SF/SG (air-cooled engines can be sensitive to oil choice; refer to manual for specific recommendations).
Coolant Type:
For the engine's oil cooler circuit (if applicable to variant) and brake fluid reservoir: DOT 3 or DOT 4 brake fluid for the hydraulic system. The manual will specify the exact type for all fluid reservoirs.
Hydropneumatic Fluid:
Citroën LHS 2 (LHM - Liquide Hydraulique Minéral) or equivalent mineral-based hydraulic fluid. This is critical and not interchangeable with standard brake fluid.
Common Faults:
Hydropneumatic system leaks (particularly sphere seals, hydraulic lines), corrosion in common areas (wheel arches, sills), ignition system reliability, carburetor issues, potential for exhaust manifold leaks.
Hydropneumatic பராம:
Regular checking and topping up of LHS 2 fluid, inspection of hoses and spheres, system pressure checks.
