Oil Change Interval:
Typically every 5,000 - 7,500 km (3,000 - 5,000 miles) or annually, whichever comes first. Refer to manual for precise intervals.
Timing Belt Interval:
Ferrari V12s of this era typically used timing chains, not belts, but regular inspection of the chain tensioner and guides is crucial. The manual will specify any recommended service for the chain system.
Engine Oil:
Multi-grade oil, typically SAE 20W-50 or 10W-40, meeting API SF or SG specifications. Consult manual for exact viscosity and API rating.
Coolant:
Mixture of antifreeze (ethylene glycol based) and distilled water, typically a 50/50 mix. Manual will specify type and capacity.
Brake Fluid:
DOT 3 or DOT 4 brake fluid. Always use fresh, sealed fluid.
Transmission Fluid Manual:
GL-4 or GL-5 gear oil, viscosity typically SAE 75W-90 or 80W-90. Check manual for specific GL rating and viscosity.
Transmission Fluid Automatic:
Dexron III or equivalent ATF fluid. Consult manual for exact specification and capacity.
Known Issues:
Common issues can include electrical gremlins due to aging wiring, fuel system component degradation (e.g., fuel accumulator, injectors), wear in suspension bushings, and potential issues with the air conditioning system. The V12 engine, while robust, requires meticulous maintenance. Transmission seals and clutch wear are also potential areas.
Heritage:
Ferrari, founded by Enzo Ferrari, is synonymous with high-performance sports cars and motorsport success, known for its iconic V12 engines and racing pedigree.
Evolution Predecessor:
The 400i evolved from the Ferrari 365 GT4 2+2, which itself replaced the 365 GT 2+2. The 400 series was Ferrari's foray into larger, more luxurious grand tourers with a focus on comfort and usability.
Evolution 400I:
The 400i (introduced in 1979) replaced the 400 automatic, featuring the Bosch K-Jetronic fuel injection system instead of carburetors, improving efficiency and emissions. It was also distinguished by updated styling cues and interior refinements.
Production Period:
1979-1985
Manufacturing Plant:
Maranello, Italy
Production Volume:
Approximately 1,330 units of the 400i were produced.
