Power Output Range:
Approximately 70 hp (1.4) to 123 hp (2.0i) depending on specific engine variant and tuning.
Torque Output Range:
Varies by engine, e.g., 1.9L engines typically produced around 150-160 Nm.
Injection Systems:
Carburetion (early 1.4/1.6) and multi-point fuel injection (MPI) for later and larger engines (e.g., Bosch Motronic).
Engine Layout:
Inline-4, front-mounted, transverse.
Engine Block Material:
Likely cast iron block with aluminum cylinder head.
Valvetrain:
SOHC (Single Overhead Camshaft) for 8-valve engines, DOHC (Double Overhead Camshaft) for 16-valve variants (e.g., XU10J4).
Oil Change Interval:
Typically every 10,000 km or 12 months, whichever comes first (or as specified by manufacturer). Check manual for exact interval based on driving conditions.
Timing Belt Interval:
Crucial interval, often around 80,000 - 120,000 km or 5-6 years, depending on engine. Belt failure can cause catastrophic engine damage.
Spark Plug Replacement:
Varies by spark plug type; typically 30,000 - 60,000 km for standard copper plugs, longer for platinum/iridium.
Engine Oil Spec:
Likely API SG/SH or ACEA A2/A3 specification. Viscosity grades like 10W-40 or 5W-40 depending on climate. Check manual for exact viscosity.
Coolant Spec:
Ethylene glycol-based antifreeze/coolant, often requiring a specific mix (e.g., 50/50 with distilled water). Typically blue or green coloured.
Brake Fluid Spec:
DOT 3 or DOT 4 brake fluid is standard for this era.
Power Steering Fluid:
Specific hydraulic fluid; often Dexron II/III ATF or a dedicated PSA fluid.
Electrical Gremlins:
Common issues can include intermittent electrical faults, particularly with window regulators, central locking, and dashboard warning lights due to age and wiring loom degradation.
Suspension Wear:
Worn suspension bushings, ball joints, and wheel bearings are common wear items leading to knocking noises and poor handling.
Engine Management:
Fuel injection system issues, idle speed control problems, and sensor failures (e.g., TPS, MAP sensor) can occur.
Cooling System:
Radiator leaks, failing water pumps, and thermostat issues can lead to overheating if not addressed.
Exhaust System:
Corrosion of the exhaust system, catalytic converter failure, and lambda sensor issues are common with age.
