Engine Type:
Alfa Romeo Boxer (Four-cylinder, horizontally opposed)
Displacement Cc:
1351cc (1.3L), 1490cc (1.5L), 1712cc (1.7L) - Depending on specific variant within 1983-1986.
Bore X Stroke Mm:
Varies by engine; e.g., 80.0 x 67.5 mm (1.3L).
Compression Ratio:
Typically around 9.0:1 to 9.5:1.
Horsepower Ps:
Approx. 75-105 PS (depending on engine size and tuning).
Torque Nm:
Approx. 110-135 Nm (depending on engine size and tuning).
Fuel Delivery:
Carbureted (e.g., twin-choke Weber/Solex) for most 1983-1986 models. Fuel injection (Bosch LE-Jetronic) introduced later in the generation and on higher trims.
Fuel Type:
Unleaded gasoline (RON 95/98, depending on market and engine variant).
Spark Plugs:
Champion N9YC, Bosch W7DC (typical recommendations, refer to manual for exact specs).
Oil Capacity Liters:
Approx. 4.0 - 4.5 liters (refer to manual for specific engine).
Coolant Capacity Liters:
Approx. 7.0 - 8.0 liters (refer to manual).
Oil Change Km Miles:
Typically every 5,000 - 7,500 km or 6 months (refer to manual for exact recommendation).
Air Filter Replacement Km Miles:
Every 15,000 - 20,000 km or annually.
Spark Plug Replacement Km Miles:
Every 20,000 - 30,000 km or as per plug type.
Timing Belt Replacement Km Miles:
Crucial for Boxer engines; typically every 60,000 - 80,000 km. Failure can cause catastrophic engine damage. Manual will detail exact interval and procedure.
Engine Oil Type:
API SG/SH, ACEA A2/A3, Viscosity SAE 10W-40 or 15W-50 (depending on climate, refer to manual).
Coolant Type:
Ethylene Glycol based antifreeze (50% mix with distilled water). Specifics in manual.
Brake Fluid Type:
DOT 3 or DOT 4.
Rust Susceptibility:
Bodywork, particularly sills, wheel arches, and floor pans, is prone to rust if not maintained. The Alfasud platform underpinning the early 33 was known for this.
Carburetor Tuning:
Carburetors can require periodic adjustment and cleaning to maintain smooth running and optimal performance.
Electrical Gremlins:
Older electrical systems can be prone to issues with wiring degradation, connectors, and grounding points.
Engine Mounts:
Hydraulic engine mounts can wear over time, leading to increased vibration.
