Depth Level:
Comprehensive: Covers everything from basic maintenance to full engine and transmission rebuilds, including detailed electrical diagnostics.
Diagnostic Tools:
Details on using basic tools and likely diagnostic procedures for ECUs (OBD I or proprietary Citroën systems for the era).
Oil Change Interval:
Typically 7,500-10,000 miles (12,000-15,000 km) or 12 months, whichever comes first.
Timing Belt Interval:
Varies by engine, typically 60,000 miles (96,000 km) or 4-5 years for petrol, and 80,000 miles (128,000 km) or 5-6 years for diesel engines (critical to check specific engine).
Engine Oil Grade:
Dependent on engine, commonly 5W-40, 10W-40, or 15W-40 (e.g., Total Quartz 7000 10W-40).
Coolant Type:
Ethylene glycol based coolant, typically purple or pink (e.g., Citroën specific Type D coolant).
Brake Fluid Type:
DOT 3 or DOT 4
Transmission Fluid Manual:
API GL-4, SAE 75W-80 or 75W-90 (e.g., Total Transmission BV 75W-80).
Transmission Fluid Automatic:
Specific ATF fluid, e.g., LT 71141 or equivalent
Common Faults Petrol:
Ignition coil failure, lambda sensor issues, idle control valve problems, exhaust manifold cracks (XU engines).
Common Faults Diesel:
Glow plug failure, injector pump issues (diesel variants), turbocharger issues (TD variants).
Suspension Wear:
Rear suspension trailing arm bushes can wear, leading to alignment issues and knocking sounds. Hydractive spheres can lose pressure over time.
Electrical Quirks:
Intermittent electrical issues due to age and wiring harness wear, especially with central locking and window mechanisms.
Rust:
Wheel arches, sills, and around the windscreen can be susceptible to corrosion on older examples.
