Engine Type:
Inline 4-cylinder petrol
Engine Displacement:
Varied, common for 1983 models included 903cc, 1116cc, 1301cc (depending on market and trim).
Fuel Delivery:
Carbureted (e.g., Weber, Solex) or early fuel injection systems (e.g., SPI - Single Point Injection) for some variants.
Horsepower Range:
Approximately 45-70 hp depending on engine size and specification.
Torque Range:
Approximately 70-95 Nm depending on engine size and specification.
Fuel Type:
Unleaded Petrol (EB/Eurogas regulations starting to influence fuel availability).
Oil Change Interval:
Typically 5,000-7,500 km (3,000-5,000 miles) or annually, whichever comes first.
Spark Plug Replacement:
Approx. 20,000-30,000 km (12,000-18,000 miles).
Timing Belt Replacement:
Crucial interval, typically 40,000-60,000 km (25,000-37,000 miles) or every 4-5 years, depending on engine and manual recommendation. Failure can cause catastrophic engine damage.
Engine Oil Type:
API SF, SAE 10W-40 or 15W-40 (check manual for specific viscosity based on climate).
Coolant Type:
Ethylene Glycol based antifreeze, 50% concentration with distilled water.
Transmission Fluid Type:
GL-4 manual transmission fluid (e.g., SAE 75W-90 or 80W-90).
Brake Fluid Type:
DOT 3 or DOT 4 hydraulic brake fluid.
Rust Corrosion:
Common issue for vehicles of this age, particularly on sills, wheel arches, and floor pans. Regular inspection and treatment are vital.
Carburetor Issues:
Can be prone to wear, leading to rough idling or poor fuel economy. Requires periodic cleaning and adjustment.
Electrical Gremlins:
Older wiring harnesses and connectors can degrade, leading to intermittent electrical faults. Thorough inspection of wiring integrity is recommended.
Suspension Wear:
Ball joints, tie rod ends, and bushings can wear over time, affecting handling and requiring replacement.
Cooling System Leaks:
Hoses and seals can deteriorate, leading to coolant leaks. Regular checks are important.
