AR01310 (1.3), AR01563 (1.5), AR30706 (1.7ie), AR30729 (1.7ie 16v)
Oil Change Interval:
Typically every 5,000-10,000 km or 6-12 months, depending on oil type and driving conditions. Manual will specify.
Timing Belt Replacement:
Crucial for boxer engines. Interval often around 60,000-80,000 km or 4-5 years. Interference engine design means failure causes severe damage.
Engine Oil Type:
API SG or higher, SAE 10W-40 or 15W-50 recommended (check manual for specific grades).
Coolant Type:
Ethylene glycol based antifreeze/coolant (e.g., Fiat Paraflu UP or equivalent).

Rust Corrosion:
Common in older Italian cars; wheel arches, sills, boot floor, and front crossmember are common areas.
Electrical Gremlins:
Can be susceptible to aging wiring, connectors, and earth points.
Carburetor Tuning:
If equipped with carburetors, they require regular tuning and synchronization for optimal performance and economy.
Gearbox Wear:
Synchromesh wear can occur on higher mileage vehicles.
Heritage:
Alfa Romeo, an iconic Italian manufacturer known for sporty sedans and coupes, with a legacy of motorsport success.
Evolution:
The 'NUOVA' (New) designation for the Type 907 marked a significant facelift and update to the original Alfa 33, introducing revised styling, improved interiors, and updated powertrains, including the 16-valve 1.7 Quadrifoglio Verde.
