The Fiat 132 C6.000 is a 2,423 cc inline — six petrol engine produced between 1977 and 1984. It served as the top — tier powerplant for the Fiat 132 range, delivering 88–92 kW (120–125 PS) with smooth refinement and strong mid — range torque. Equipped with a single overhead camshaft (SOHC), 12 — valve head, and twin — choke Weber 36 DOHC carburettor, it offered enhanced performance and cruising comfort over four — cylinder variants.

All C6.000-equipped Fiat 132 models comply with ECE Regulation 15 Phase II (VCA UK Type Approval #VCA/ECE/15/IT/842).
The Fiat C6.000 is a 2,423 cc inline-six SOHC petrol engine designed for executive sedans (1977–1984). It combines twin-choke carburettor fuel delivery with robust iron-block construction to deliver smooth power delivery and enhanced drivability. Designed to meet ECE R15 Phase II standards, it balances refinement with mechanical reliability for long-distance motoring.

The Fiat C6.000 was used exclusively across Fiat's 132 series platforms with longitudinal mounting and no licensed external usage. This engine received platform-specific adaptations—twin-choke Weber 36 DOHC in Super and Elite trims—and from 1980, the facelifted models adopted revised EGR calibration and improved oil pump drive, creating minor service part distinctions. All adaptations are documented in OEM technical bulletins.
The C6.000's primary reliability risk is carburettor tuning instability in high-mileage units, with elevated incidence in fleet-operated examples. Internal Fiat service reports from 1983 noted a significant share of pre-1980 engines requiring EGR valve replacement or carburettor overhaul beyond 80,000 km, while UK DVSA historic vehicle inspections cite mixture imbalance as a frequent cause of failed emissions tests. Extended oil intervals and use of non-specified lubricants accelerate wear, making adherence to service schedules critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
Yes, when properly maintained. The C6.000 features a robust iron block and proven inline-six design, making it durable over time. Early models (pre-1980) may show EGR or carburettor issues, but post-1980 revisions improved reliability. Regular oil changes with correct 10W-40 mineral oil and carburettor servicing are essential for long-term operation.
Common issues include carburettor mixture drift, EGR valve clogging, oil leaks from gaskets, and timing chain wear in early models. These are documented in Fiat service literature and observed in historic vehicle inspections. Upgrading to post-1980 components and using ethanol-resistant carburettor parts can mitigate many concerns.
The C6.000 was used exclusively in the Fiat 132 range from 1977 to 1984. It powered the Super, Elite, and select LX trims. No other Fiat platforms used this engine, and it was not licensed to other manufacturers.
Yes, within mechanical limits. The Elite variant already features tuned intake and ignition for 92 kW output. Enthusiasts often upgrade to performance camshafts, high-flow heads, and electronic ignition. However, tuning should preserve the engine's balance and avoid over-revving, as the crankshaft and rods are not designed for extreme RPM.
Moderate by modern standards. In a Fiat 132 2.4L, fuel consumption averages ~12.5 L/100km (city) and ~9.0 L/100km (highway), or approximately 23 mpg UK combined. The inline-six design provides smooth cruising efficiency but consumes more fuel than four-cylinder counterparts under spirited driving.
No. The C6.000 uses a non-interference valve train design. If the timing chain fails or skips, the pistons will not contact the valves, preventing catastrophic internal damage. However, immediate repair is still advised to avoid secondary issues like misfires or poor compression.
Fiat specifies SAE 10W-40 mineral oil meeting API SE/CC standards. This viscosity protects the chain-driven camshaft and solid lifters effectively. Synthetic oils are not recommended unless seals are upgraded, as they may increase seepage in older gaskets. Oil should be changed every 15,000 km or annually.
