Service Intervals Engine Oil
Oil Change Interval:
Typically every 10,000-15,000 miles or 12 months, but check manual for exact figures based on engine type and driving conditions.
Service Intervals Filters
Air Fuel Filter Replacement:
Air filter usually every 20,000-30,000 miles; fuel filter every 30,000-40,000 miles for diesels.
Engine Oil Type:
Viscosity grades like 5W-40 or 10W-40, often meeting ACEA specifications (e.g., ACEA B3/B4 for diesels). Specific grades detailed in manual.
Coolant Type:
Antifreeze coolant, typically a 50/50 mix of antifreeze and distilled water. Specific Citroën approved coolant recommended.
Brake Fluid Type:
DOT 4 brake fluid.
Hydropneumatic Fluid:
Citroën LHS 2 (or compatible mineral-based fluid for later models/conversions) for the suspension system. Manual will specify.
Hydropneumatic System Leaks:
Common for spheres to lose pressure over time; seals in rams and pumps can also leak.
Diesel Engine Glow Plugs:
Glow plug failure leading to hard starting in cold weather.
Fuel Injection Pump Issues:
Potential issues with older rotary injection pumps (XUD) or common rail components (HDi) leading to performance loss or starting problems.
Electrical Gremlins:
As with many older French cars, some minor electrical issues can occur, often related to wiring harnesses or earth points.
