Engine Options 1995:
Various petrol and diesel engines, including the PRV V6 (e.g., 3.0L V6 12V/24V), XM Turbo D (2.1L turbodiesel), and potentially early XUD turbodiesel variants.
Typical Power Output V6:
Approx. 170-200 hp for V6 variants, depending on configuration.
Typical Torque V6:
Approx. 240-270 Nm for V6 variants.
Petrol Injection Type:
Multi-Point Fuel Injection (MPI) for petrol engines.
Diesel Injection Type:
Direct injection (IDI or DI) for turbodiesel variants, potentially early common rail on later models.
Oil Change Interval:
Typically every 7,500-10,000 miles (12,000-15,000 km) or 12 months, depending on driving conditions and engine type.
Timing Belt Replacement:
Crucial for V6 petrol engines; usually every 60,000-80,000 miles (100,000-120,000 km). Check specific engine variant.
Engine Oil Type Petrol:
API SG or SH, ACEA A2/A3, viscosity typically 5W-40 or 10W-40. Consult manual for exact spec.
Engine Oil Type Diesel:
API CG-4 or CH-4, ACEA B3/B4, viscosity typically 5W-40 or 10W-40. Consult manual for exact spec.
Suspension Fluid Type:
Citroën's LDS (Low Density Synthetic) fluid for later models, or older LHS (Low Density Synthetic) fluid for earlier/some 1995 models. **Crucially, never mix or substitute with standard hydraulic fluid.**
Transmission Fluid Automatic:
Dexron III or equivalent.
Suspension Leaks:
Hydropneumatic system can develop leaks in spheres, pipes, or seals, leading to ride height issues or system failure. Regular fluid changes and checks are vital.
Electrical Gremlins:
Complex electrical systems can be prone to intermittent faults due to wiring issues, aging components, or poor grounding. The manual's wiring diagrams are invaluable.
Engine Management Complexity:
Specific engine issues vary, but V6 engines can be sensitive to maintenance, and turbodiesels require clean fuel and regular turbo checks.
Exhaust Guides V6:
Wear on exhaust valve guides in some V6 variants, leading to oil consumption.
