🔧 Maintenance

Timing Belt Replacement:

Recommended every 30,000 miles (approx. 50,000 km) or 5 years, whichever comes first. Critical for V8 Ferrari engines.

Oil And Filter Change:

Recommended every 5,000 miles (approx. 8,000 km) or 6-12 months, depending on usage and oil type.

Valve Adjustment:

Typically required every 15,000-30,000 miles, depending on manufacturer's specific recommendations and engine condition.

Engine Oil Type:

Refer to manual for specific API/ACEA ratings and viscosity grades (e.g., SAE 20W-50 or 10W-40 depending on climate), often a high-quality synthetic is recommended.

Coolant Type:

Ethylene glycol-based coolant, typically a 50/50 mix with distilled water. Manual will specify Ferrari approved types.

Brake Fluid Type:

DOT 3 or DOT 4 brake fluid.

Transmission Fluid Type:

Manual transmission fluid (GL-4 or GL-5 rated) with appropriate viscosity for ambient temperatures. Manual will specify precise type and capacity.

Timing Belt Tensioner Failure:

A critical failure point if belts are not replaced at recommended intervals. Manual details inspection and replacement procedures.

Fuel Injection System Issues:

K-Jetronic systems can be sensitive to air leaks, fuel pressure inconsistencies, and aging components. Manual provides diagnostic steps for these.

Cooling System Leaks:

Older hoses, seals, and radiators can develop leaks. Manual covers inspection and replacement of these components.

Electrical Gremlins:

Aging wiring harnesses and connectors can lead to intermittent electrical faults. Detailed wiring diagrams in the manual are essential for diagnosis.

📚 Vehicle History

Ferrari Legacy:

Continuation of Ferrari's lineage of V8 mid-engined sports cars, building on the success of the Dino series and earlier V8 models.

308 To 328 Transition:

The 328 was an evolution of the 308, featuring a larger displacement engine, updated styling cues (particularly revised front and rear bumpers), and improved aerodynamics. The 308 itself transitioned from carbureted to fuel-injected, and then to the 4-valve QV model.

308 Qv Production:

1982-1985

328 Production:

1985-1989

Manufacturing Plant:

Maranello, Italy

🏆 Awards & Recognition

Model Reputation:

Both the 308 and 328 are considered iconic and highly desirable classic Ferraris, celebrated for their Pininfarina styling, V8 engine sound, and driving experience.
