Oil Change Interval:
Typically 7,500-10,000 miles or 12 months, depending on driving conditions and oil type (refer to manual for exact spec).
Timing Belt Replacement:
Crucial. Typically every 60,000 miles or 4-5 years for petrol TU engines. Diesel XUD engines usually have timing chains, but check manual.
Engine Oil Petrol Common:
API SG or SH, SAE 10W-40 or 15W-50 (check manual for specific engine and climate).
Engine Oil Diesel Common:
API CF or CG-4, SAE 10W-40 or 15W-40 (check manual).
Coolant Type:
Ethylene glycol-based antifreeze, 50% concentration with distilled water. Citroën specific coolant may be recommended.

DOT 3 or DOT 4 (check manual).
Transmission Fluid Manual:
API GL-4, SAE 75W-80 or 80W-90 gear oil (check manual for specific gearbox).
Electrical Gremlins:
Age-related issues with wiring looms, connectors, and earth points are common. Faulty central locking or window regulators.
Suspension Wear:
Front suspension components (ball joints, drop links, wishbone bushes) can wear, leading to knocking noises. Torsion bar rear suspension requires proper adjustment/maintenance.
Rust:
Prone to rust in wheel arches, sills, and subframes, especially in areas with road salt. Early inspection and treatment are vital.
Engine Overheating:
Can occur due to radiator blockages, faulty thermostats, or worn water pumps. Regular coolant changes are important.
Carburetor Issues Petrol:
Carburetor models can be sensitive to gumming and require regular cleaning and adjustment for optimal performance.
Diesel Glow Plugs:
Diesel engines require functional glow plugs for cold starting. Faulty plugs will prevent starting in cold weather.
