Engine Types Covered:
Alfa Romeo Twin Spark (e.g., 1.7L, 2.0L) and Alfa Romeo V6 Busso (e.g., 3.0L).
Power Output:
Varies by specific engine: 1.7L Twin Spark ~115-129 hp, 2.0L Twin Spark ~140-150 hp, 3.0L V6 ~188-210 hp.
Torque:
Varies by specific engine, e.g., 2.0L Twin Spark ~186 Nm, 3.0L V6 ~245 Nm.
Injection Type:
Bosch L-Jetronic or Motronic electronic fuel injection (EFI).
Fuel Type:
Unleaded gasoline (Petrol)
Spark Plugs:
Twin Spark engines feature two spark plugs per cylinder. Specific types and gap settings detailed in the manual.
Timing Belt:
Critical for Twin Spark engines. Replacement intervals and procedures are vital.
Oil Change:
Typically 10,000-15,000 km or annually, depending on driving conditions and oil used. Manual will specify exact intervals and oil types.
Timing Belt Replacement:
Crucial for Twin Spark engines, typically every 60,000-80,000 km or 5 years. Manual will provide precise interval and associated tensioner/pulley replacement.
Spark Plug Service:
Twin Spark engines require dual spark plug replacement. Intervals often 30,000-60,000 km.
Engine Oil:
Likely API SG/SH or ACEA A2-96/A3-98 specification, viscosity grades like 10W-40 or 15W-50. Manual specifies exact grades and capacities.
Coolant:
Ethylene glycol based antifreeze, usually pink or red in color, mixed 50/50 with distilled water. Manual will specify type and capacity.
Brake Fluid:
DOT 3 or DOT 4. Manual specifies type and replacement interval.
Transmission Fluid:
Manual transmission fluid (e.g., SAE 75W-90 GL-4/GL-5). Automatic transmission fluid (e.g., Dexron III or equivalent) for auto models. Capacities specified.
Twin Spark Reliability:
Timing belt failure is catastrophic. Coil packs and ignition issues can arise. Valve stem seals can wear, leading to oil consumption.
Rust:
Common on older Italian cars, especially wheel arches, sills, and door bottoms. Manual may offer minor repair guidance.
Electrical Gremlins:
Aging wiring and connectors can lead to intermittent issues. Fuse box corrosion is also a possibility.
Busso V6 Maintenance:
Requires regular attention to timing belts and oil changes. Can be prone to oil leaks as it ages.
