Engine Type:
Air-cooled, flat-four (boxer) engine
Engine Displacement:
Typically 1015cc to 1222cc for GS, GSA models up to 1299cc for later GSA variants.
Power Output:
Varies by engine size, e.g., 1015cc: ~56 hp; 1222cc: ~62 hp; GSA 1300: ~65 hp.
Torque Output:
Varies by engine size, e.g., 1015cc: ~76 Nm; 1222cc: ~87 Nm.
Fuel Delivery:
Initially Carburettor (e.g., Solex, Weber), later models or variants may have fuel injection (e.g., Bosch L-Jetronic on GSA).
Oil Change Interval:
Typically every 5,000 - 7,500 km (refer to specific manual for precise intervals).
Lubrication Points:
Regular greasing of suspension components and chassis lubrication points.
Engine Oil:
API SG or SF, SAE 20W-50 or 10W-40 (air-cooled engine may require specific types; consult manual).
Hydraulic Fluid:
Citroën LHS 2 or LHS 3 hydraulic fluid for suspension and brakes.
Brake Fluid:
DOT 3 or DOT 4 (ensure compatibility with hydraulic fluid system if shared).
Hydropneumatic Suspension:
Leaking spheres, pressure loss, seal wear, hydraulic fluid contamination.
Engine Cooling:
Air-cooled, so overheating is rare unless airflow is severely restricted. Ignition timing and carburetion are critical.
Electrical Corrosion:
Corrosion in connectors and wiring harnesses, especially due to age.
Rust:
Common on older vehicles, particularly sills, wheel arches, and floor pans.
Citroen Philosophy:
Citroën's reputation for innovation, aerodynamic design, and advanced engineering, particularly with hydropneumatic suspension.
Gs Introduction:
The GS was launched in 1970, replacing the Ami 8. It was praised for its styling, comfort, and handling.
Gsa Introduction:
The GSA was an updated version introduced in 1979, featuring improved aerodynamics, a revised interior, and the new 'GSA' badge.
Production Period:
GS: 1970-1986; GSA: 1979-1986
Manufacturing Location:
France (primarily Rennes-sur-Vilaine)
