Engine Oil Change:
Every 5,000 - 7,500 km (3,000 - 4,500 miles) or 6-12 months, whichever comes first. Consult manual for specifics based on usage.
Transmission Fluid Change Manual:
Inspect annually; change every 40,000 - 60,000 km (25,000 - 37,000 miles).
Transmission Fluid Change Automatic:
Inspect every 10,000 km (6,000 miles); change fluid and filter every 30,000 - 40,000 km (18,000 - 25,000 miles).
Hydropneumatic Fluid Check:
Check level and condition regularly, typically at every oil change. Fluid change recommended every 60,000 km (37,000 miles).
Timing Belt Replacement:
Recommended replacement interval of 60,000 - 80,000 km (37,000 - 50,000 miles) or 5 years.
Engine Oil Type:
API SF/CD rated, SAE 20W-50 or 10W-40 depending on climate. Consult manual for specific recommendations.
Hydropneumatic Fluid:
Citroën LHS (or equivalent LHM - mineral oil based for later models, but LHS mineral fluid likely for 1975). Manual will specify correct fluid type.
Brake Fluid:
DOT 3 or DOT 4 (consult manual for exact specification).
Hydropneumatic Suspension:
Leaking spheres, failing pump, worn height correctors, and hose degradation are common wear items. Regular fluid maintenance is crucial.
Electrical Gremlins:
Older wiring looms can degrade, leading to intermittent faults in lighting, instrumentation, and other electrical components. Fuse box connections also require attention.
Rust:
Like many cars of this era, rust can be a concern, particularly in sills, wheel arches, and floor pans. Regular inspection and preventative treatment are advised.
Carburetor Tuning:
Weber carburetors require periodic adjustment and cleaning to maintain smooth running and optimal fuel economy.
