Engine Family:
Citroen 'Douvrin' (various displacements possible for CX model line)
Engine Displacements Common:
Likely 2.0L (2000cc), 2.2L (2150cc, e.g., CX 22 TRS), 2.5L (2500cc, e.g., CX 25 GTI, CX 25 TRD Turbo-D).
Horsepower Range:
Varies by engine; typically 106 hp for 2.0L to 164 hp for 2.5L Turbocharged models.
Torque Range:
Varies by engine; diesel variants offered significantly higher torque.
Fuel Delivery:
Carburetion (e.g., Solex, Weber) on naturally aspirated petrol engines; Bosch L-Jetronic or K-Jetronic fuel injection on performance models; indirect injection for diesel models.
Ignition Type:
Conventional distributor-based ignition system, potentially with electronic control depending on exact variant.
Standard Transmission:
4-speed or 5-speed manual transmission.
Optional Transmission:
3-speed or 4-speed automatic transmission (e.g., Citroen's own design or ZF).
Features:
Manuals will cover clutch operation, gear selection mechanisms, and torque converter assembly for automatics.
Wheelbase:
Approx. 2900 mm (114.2 in) for saloon models, longer for estate (Break) models.
Length:
Saloon: Approx. 4780 mm (188.2 in); Estate: Approx. 4980 mm (196.1 in).
Width:
Approx. 1770 mm (69.7 in).
Height:
Approx. 1370 mm (53.9 in).
Curb Weight:
Varies significantly by engine and equipment, typically ranging from 1300 kg to 1500 kg.
Gross Vehicle Weight:
Not specified, but would be detailed in the manual.
Historical Safety Standards:
Vehicles from this era generally adhered to national safety standards, with less standardized global ratings than modern vehicles.
Active Safety:
Four-wheel disc brakes (standard on most models), power steering.
Passive Safety:
Reinforced body structure, impact-absorbing steering column (though less advanced than modern standards).
Audio System:
Likely factory-fitted radio/cassette player, with options for aftermarket upgrades detailed in the manual.
User Interface:
Minimalist dashboard design with centralized controls and unique 'satellite' stalks for wipers, lights, and indicators.
Driver Assistance Features:
Power steering, variable assist steering (DIRAVI system on higher trims), cruise control (optional on some models).
Connectivity Features:
Not applicable for the era; limited to basic radio connectivity.
Oil Change Interval:
Typically every 5,000 - 10,000 km (3,000 - 6,000 miles) or annually, depending on oil type and usage.
Transmission Fluid Change:
Automatic transmission fluid typically recommended every 40,000 - 60,000 km (25,000 - 37,000 miles); manual transmission fluid every 80,000 - 100,000 km (50,000 - 60,000 miles).
Engine Oil Specification:
Viscosity grades like 10W-40 or 15W-50, meeting API SF/SG specifications or equivalent. Manual will specify exact approvals.
Hydropneumatic Fluid:
LHM (Liquide Hydraulique Minéral) - specific Citroën designation (e.g., LDS fluid precursors). Crucial to use the correct type for suspension and brakes.
Brake Fluid:
DOT 3 or DOT 4 (if separate from hydropneumatic system, unlikely on CX).
Coolant:
Ethylene glycol-based coolant with anti-corrosion inhibitors. Manual will specify mix ratio.
Common Issues:
Hydropneumatic system leaks (suspension, brake accumulator), electrical gremlins, rust (especially in wheel arches, sills), carburetor/injection system tuning, aging rubber components.
Specific Components To Check:
Hydraulic fluid levels and condition, sphere pressure, suspension height regulators, electrical connections, exhaust condition.
Citroen Legacy:
Citroën is renowned for innovation, particularly in suspension systems and aerodynamic design, stemming from the Traction Avant and DS.
Cx Development:
The CX succeeded the iconic Citroën DS, inheriting its hydropneumatic suspension and advanced design philosophy. It was known for its distinctive aerodynamic 'torpedo' shape.
Production Period:
1974-1991. The 1990 model year represents the later stages of its production life.
Manufacturing Location:
France (primarily Rennes-sur-Vitre).
