Engine Oil:
Refer to manual for specific viscosity (e.g., 10W-40 or 20W-50 API SG or similar).
Coolant:
Mixture of antifreeze and distilled water, specific type recommended by Citroën.
Hydropneumatic Fluid:
Citroën LHS 2 (LHM - Citroën Hydraulique Minéral) is the correct fluid for later models and systems. Early models might have used a different type, check manual.
Transmission Fluid:
Refer to manual for specific type (e.g., GL-4 gear oil).
Rust:
Prone to rust, especially in common areas like sills, wheel arches, and door bottoms.
Hydropneumatic Suspension:
Leaking spheres, worn seals in hydraulic rams, and pump issues can occur over time.
Electrical Gremlins:
Older wiring can become brittle and connections corroded, leading to intermittent electrical faults.
Cooling System:
Air-cooled nature means careful monitoring of airflow and heat dissipation is crucial. Blocked cooling fins can lead to overheating.
