Engine Type:
Air-cooled, two-cylinder, overhead-valve (OHV)
Displacement:
479 cc (early models), later 500 cc, 600 cc (in 500L and 500R variants).
Horsepower:
13-22 hp (depending on variant and year)
Torque:
Approx. 30-40 Nm (depending on variant and year)
Carburetor:
Solex 28-PCI or similar downdraft carburetor.
Fuel Type:
Unleaded gasoline (historically, leaded gasoline was common).
Oil Capacity:
Approx. 2.5 - 3.0 liters (depending on model).
Cooling Method:
Forced air cooling via a fan driven by the crankshaft.
Oil Change:
Every 5,000 km or 6 months (whichever comes first).
Spark Plugs:
Inspect every 10,000 km, replace as needed.
Ignition Timing:
Check and adjust at every major service or if running issues occur.
Engine Oil:
SAE 20W-50 or SAE 30 (depending on climate and manufacturer recommendation). Check manual for specific API ratings.
Coolant:
Specific coolant mix as per Fiat recommendations (usually a 50/50 antifreeze/water mix).
Brake Fluid:
DOT 3 or DOT 4 hydraulic brake fluid.
Gearbox Oil:
SAE 90 hypoid gear oil.
Rust:
Prone to rust, especially around wheel arches, sills, and floor pans. Thorough inspection and preventative treatment are crucial.
Engine Overheating:
Due to the air-cooled nature and small displacement, overheating can occur in sustained high temperatures or heavy traffic. Ensure cooling fan and shrouds are in good condition.
Synchromesh Wear:
Early transmissions lack synchromesh, requiring careful gear changes. Synchromesh units can wear over time, leading to difficult shifting.
Carburetor Tuning:
The simple carburetor requires periodic adjustment for optimal performance and fuel economy.
Electrical Connections:
Older wiring can degrade, leading to intermittent electrical faults. Inspection and maintenance of connections are important.
