Engine Code:
Likely variants of the Fiat '100' series engines (e.g., 127A.000, 127A1.000).
Displacement:
Commonly 903 cc (0.9 L), later models and variants could have 1049 cc (1.0 L) or 1301 cc (1.3 L) engines.
Horsepower:
Around 45-55 PS (33-40 kW) for 903cc, higher for larger displacement variants.
Torque:
Specific torque figures vary by engine, but generally adequate for its class.
Fuel Delivery:
Single or twin-choke Weber or Solex carburetors. Some later models or specific markets might have featured electronic fuel injection for certain engines.
Fuel Type:
Unleaded gasoline (petrol), with specific octane rating recommendations.
Body Styles:
2-door hatchback, 3-door hatchback, 4-door hatchback (less common), estate/van variant (127 Panorama/Fiorino).
Length:
Approximately 3.65 meters (143.7 inches) for the 2/3-door hatch.
Width:
Approximately 1.53 meters (60.2 inches).
Height:
Approximately 1.37 meters (53.9 inches).
Curb Weight:
Around 750-850 kg (1653-1874 lbs) depending on specification.
Crash Test Data:
Limited formal crash test data available for this era compared to modern standards. Likely basic safety features.
Active Safety:
Standard hydraulic braking system. Optional front disc brakes, rear drum brakes.
Passive Safety:
Seat belts (likely lap belts in front, lap belts in rear in base models), reinforced passenger cell.
Oil Change Interval:
Typically every 5,000 - 7,500 km (3,000 - 4,500 miles) or 6-12 months, depending on driving conditions and oil type.
Filter Replacement:
Oil filter should be replaced with every oil change. Air filter and fuel filter replacement intervals will be specified in the manual.
Spark Plug Replacement:
Recommended replacement every 10,000 - 20,000 km (6,000 - 12,000 miles), depending on plug type and condition.
Timing Belt Chain:
The 127 uses a timing chain for its overhead valve engines, which typically requires less frequent replacement than a belt, but checks for wear and tension are crucial.
Engine Oil:
API SE/SF classification. Viscosity typically SAE 15W-40 or 20W-50, depending on ambient temperature. Manual will specify exact grades and capacities.
Coolant:
Ethylene glycol-based antifreeze mixture. Capacity approximately 4.5-5 liters. Manual will specify concentration and type.
Brake Fluid:
DOT 3 or DOT 4 hydraulic brake fluid. Capacity approximately 0.5-1 liter for a full system flush and refill.
Transmission Fluid:
Manual transmission gear oil, typically API GL-4 specification. Viscosity SAE 75W-90 or 80W-90. Capacity around 2.0-2.5 liters.
Body Corrosion:
Common issue for vehicles of this era, particularly wheel arches, sills, floor pans, and door bottoms. Rust prevention and repair are key.
Carburetor Issues:
Carburetors (Weber/Solex) can become gummed up and require cleaning or rebuilding, affecting idle and performance. Ignition timing and carburetor tuning are critical.
Electrical Gremlins:
Aging wiring harnesses, corroded connections, and failing switches can lead to intermittent electrical problems.
Suspension Wear:
Ball joints, tie rod ends, and bushings can wear over time, affecting steering and ride quality. Regular inspection is recommended.
Cooling System Leaks:
Radiator, hoses, and water pump can develop leaks, especially with age. Regular checks and timely replacement are necessary.
