🔧 Maintenance

Oil Change:

Every 5,000 km (3,000 miles) or annually. Refer to manual for specific oil type and viscosity.

Air Filter:

Inspect every 5,000 km (3,000 miles), replace as needed.

Spark Plugs:

Replace every 20,000 km (12,000 miles) or as specified. Refer to manual for correct type and gap.

Coolant Flush:

Every 2 years or 40,000 km (24,000 miles).

Engine Oil:

SAE 20W-50 or SAE 10W-40, API SF or SG service classification (check manual for precise recommendation).

Transmission Fluid:

GL-4 SAE 75W-90 or SAE 80W-90 gear oil.

Brake Fluid:

DOT 3 or DOT 4 (glycol-based) hydraulic brake fluid.

Coolant:

Ethylene glycol based antifreeze (50% mixture with distilled water).

Engine:

SPICA fuel injection system can be complex to tune and requires specialized knowledge. Ignition system can be prone to issues if not properly maintained. Potential for oil leaks from V8 seals and gaskets.

Electrical:

Wiring harness degradation over time is common in classic cars. Lucas electrical components (if fitted) can be a source of issues. Headlight pop-up mechanisms can be slow or fail.

Body Chassis:

Rust can be a significant issue, particularly in the sills, wheel arches, and around the rear axle. Door seals and window seals degrade, leading to water ingress.

Suspension Steering:

Wear in suspension bushings and ball joints is common due to age and mileage. Power steering systems can develop leaks.

📚 Vehicle History

Heritage:

Alfa Romeo, an Italian manufacturer with a rich racing history and a reputation for building sporty, stylish automobiles, particularly known for its inline-four and V6 engines before the Montreal.

Conception:

The Montreal was conceived as a showcase vehicle for the 1967 Montreal World's Fair (Expo 67), initially presented as a concept car named 'Carabo'. It was based on a shortened Giulia GT chassis and featured the V8 engine developed for the Tipo 33 racing car.

Production Start:

Production began in 1970.

Engine Change:

The initial concept featured a 2.0L V8, but production models received the larger 2.6L version derived from the Alfa Romeo T33/2 Stradale. Later in its production, a less powerful 2.0L version was offered in Italy to circumvent luxury taxes on cars over 2.0 liters.

Production Years:

1970-1977

Production Volume:

Approximately 3,925 units were produced in total.

Manufacturing Location:

Milan, Italy
