Configuration:
Inline-4 cylinder, typically with SOHC or DOHC valve actuation depending on specific engine variant.
Power Output Range:
Approximately 70-100 hp for naturally aspirated petrol, 90-105 hp for turbo-diesel variants, depending on specific engine.
Injection Type:
Multi-point fuel injection (MPI) for petrol engines; Direct injection (DI) for diesel engines.
Coolant Type:
Ethylene glycol-based coolant, typically requiring a 50/50 mix with distilled water. Manual will specify exact Citroën coolant type/number.
Oil Viscosity Recommendation:
Likely 5W-40 or 10W-40 for both petrol and diesel engines, subject to ambient temperature. Manual will provide precise recommendations.
Belt Or Chain:
Timing belt driven for most XU series engines. Critical replacement interval detailed in manual.
Euro Ncap Rating:
Not formally rated under modern Euro NCAP standards for models from this era. Earlier safety assessments were less standardized.
Braking System Type:
Front: Ventilated discs; Rear: Drums (common) or Discs (on higher trims/performance models). ABS likely optional or standard on higher trims.
Airbags:
Driver airbag likely standard on later models, passenger airbag optional or introduced later in the production run. Manual will detail specific fitment.
Seatbelts:
Front and rear seatbelts. Pre-tensioners may be present on front belts in later models. Manual will detail adjustments and maintenance.
Radio System:
Factory fitted radio-cassette players were common, often with basic digital tuning. Steering wheel remote controls were an option on higher trims.
ABS:
Anti-lock Braking System was an optional extra on many models or standard on higher specifications, particularly later in the production run.
Air Conditioning:
Air conditioning was an optional feature, often found on GTi or more luxurious trim levels.
Hydractive Suspension:
Higher-spec models were equipped with the innovative Hydractive suspension system, offering adjustable ride comfort and handling characteristics. This manual will detail its operation and maintenance.
Oil Change Interval:
Typically 7,500-10,000 miles (12,000-15,000 km) or 12 months, whichever comes first. Manual will specify exact intervals for each engine.
Timing Belt Replacement:
Crucial interval, typically around 60,000-80,000 miles (100,000-120,000 km) or 5-6 years for XU engines. Failure can cause catastrophic engine damage. Manual will provide the definitive interval.
Brake Fluid Type:
DOT 4 brake fluid. Manual will specify the exact PSA standard.
Power Steering Fluid:
Hydraulic mineral oil (LHM) for models with self-levelling suspension, or specific power steering fluid for conventional systems. Manual is critical here.
Suspension Components:
Rear suspension trailing arm bearings and associated seals can wear, leading to knocking or excessive play. Hydractive system spheres can lose pressure over time.
Cooling System:
Radiator leaks and thermostat issues are common in older vehicles. Heater matrix can also fail.
Electrical Gremlins:
Corroded earth points, failing relays, and intermittent faults in dashboard illumination and central locking are not uncommon due to age.
Exhaust System:
Corrosion of the exhaust system, particularly the rear silencer and catalytic converter, is typical for vehicles of this age.
Citroen Philosophy:
Citroën has a long history of innovation, particularly in suspension technology (hydro-pneumatic, hydractive systems) and aerodynamics, aiming to provide comfort and distinctive design.
