Operating System Compatibility:
All versions of Windows and macOS.
Crash Test Results:
No formal modern crash test ratings available for this era and model, but designed with a deformable front and rear structure for energy absorption.
Braking System:
Hydraulically assisted disc brakes at the front, drum brakes at the rear. Self-adjusting mechanisms.
Seatbelts:
Provision for seat belts, often front lap/shoulder belts. Rear lap belts.
Engine Oil Change:
Typically every 5,000 - 7,500 km (3,000 - 4,500 miles) or 6-12 months, depending on usage.
Suspension Fluid Check:
Regular checks for leaks and proper system pressure, with fluid flushing and replacement recommended at longer intervals (e.g., 40,000-60,000 km).
Tune Up:
Spark plug replacement, ignition timing adjustment, and carburetor tuning recommended annually or every 10,000-15,000 km.
Engine Oil:
SAE 20W-50 or SAE 15W-40 (API SF or SG classification, or equivalent for the era). Specific Citroën grades may apply.
Suspension Fluid:
LHM (Liquide Hydraulique Minéral) fluid, typically Citroën's own specification, often green in colour.
Brake Fluid:
DOT 3 or DOT 4 brake fluid (ensure compatibility with hydraulic systems).
Transmission Fluid:
GL-4 gear oil (e.g., SAE 75W-90 or SAE 80W-90).
Engine Wear:
Wear in valve guides and seats due to air cooling, potential for oil leaks from cylinder head gaskets or pushrod tubes.
Suspension Leaks:
Hydropneumatic spheres and seals can degrade over time, leading to 'sagging' suspension. Hydropneumatic fluid contamination.
Electrical Reliability:
Older wiring harnesses and connectors can corrode or become brittle, leading to intermittent electrical faults. Generator/alternator issues.
Rust:
Prone to rust in common areas like wheel arches, sills, door bottoms, and floor pans due to its age and construction.
Carburetor Tuning:
Carburetors can be sensitive to adjustment and require regular cleaning and tuning for optimal performance.
Citroen Philosophy:
Citroën's tradition of innovation, distinctive design, and advanced engineering, particularly in suspension systems.
Gs Introduction:
The GS was introduced in 1970 as a mid-size family car, succeeding the Ami 8 and bridging the gap to the larger DS.
Gsa Introduction:
The GSA was a significant facelift and update of the GS, introduced in 1979, featuring improved aerodynamics, a new dashboard, and updated mechanicals.
Production Period:
GS: 1970-1980, GSA: 1979-1986.
Manufacturing Location:
France (primarily Rennes-sur-Vilaine).
