🔧 Maintenance

Oil Change:

Typically every 3,000 miles (approx. 5,000 km) or 3-6 months, depending on driving conditions. Consult manual for precise intervals.

Tune Up:

Spark plug replacement, ignition timing adjustment, carburetor adjustment typically recommended at 12,000-15,000 mile intervals.

Engine Oil:

API SF or SG service classification, SAE 10W-30 or 10W-40 recommended for most conditions. Consult manual for exact specifications and viscosity based on temperature.

Coolant:

Ethylene glycol-based antifreeze mixed with distilled water. Datsun Blue or equivalent coolant recommended. Consult manual for specific type and mixture ratio.

Brake Fluid:

DOT 3 or DOT 4 automotive brake fluid. Always use fresh fluid from a sealed container.

Transmission Fluid:

Manual: SAE 80W-90 gear oil. Automatic: Dexron II or equivalent ATF.

Clutch Fluid:

Typically uses brake fluid (DOT 3/4) for hydraulic clutch systems. Consult manual for specific type.

Gear Oil:

Differential typically requires SAE 90 gear oil (GL-5 specification often recommended for limited-slip differentials, but standard gear oil for open differentials).

Rust Corrosion:

Common issue in the lower body panels, wheel wells, and frame due to age and environmental exposure. Regular inspection and preventative treatment are crucial.

Carburetor Issues:

Carburetors can become gummed up with age, leading to rough idling, poor acceleration, or starting problems. Rebuilding or replacing the carburetor may be necessary.

Ignition System:

Points and condenser can wear out, affecting ignition timing and performance. Early electronic ignition systems can also develop faults.

Suspension Wear:

Bushings, ball joints, and shock absorbers can wear out, leading to loose steering, poor handling, and clunking noises.

📚 Vehicle History

Datsun Legacy:

Datsun (Nissan's export brand) was known for reliable, affordable, and sporty vehicles, with the 510 being a celebrated model often compared to European sports sedans of its time.

Fifth Generation:

The 1979 model year often falls under the B310 generation (Sunny/Pulsar), which had evolved from the original Datsun 510 (PL510) and subsequent models. The nomenclature can be complex as the '510' spirit carried through.

Chassis Evolution:

The 1979 model year can be linked to the B310 platform, which succeeded the A210 generation. While the '510' name was largely phased out in favor of 'Sunny' or 'Pulsar' in many markets by this time, the spirit and engineering lineage of the original 510 continued. The manual accurately targets this specific iteration of Datsun's compact offering.

Manufacturing Locations:

Primarily Japan, with potential assembly in other international locations.

🏆 Awards & Recognition

Motorsport Legacy:

The Datsun 510 has a strong motorsport heritage, particularly in touring car racing (e.g., Trans-Am series), which contributed to its sporty image and popularity.
