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.
Fitted to the Fiat 132 Super and Elite trims, the C6.000 was engineered for executive comfort and long-distance driving, targeting fleet and private users seeking a refined alternative to contemporary European sedans. Its design emphasized smoothness and durability, with emissions control achieved via exhaust gas recirculation (EGR) and secondary air injection, meeting ECE Regulation 15 Phase II standards.
A documented engineering update occurred in 1980, referenced in Fiat Service Bulletin 80-ME-06, introducing a revised cylinder head with improved port flow and updated EGR valve calibration. This addressed reports of idle instability and hot-start hesitation in high-temperature climates. Later production units also featured a modified oil pump drive to reduce wear under sustained highway operation.
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 inline-six configuration provides smooth power delivery ideal for relaxed cruising but requires adherence to 15,000 km service intervals to maintain timing chain and bearing health. SAE 10W-40 mineral oil is recommended for compatibility with older seals and chain tensioner design. Carburettor models benefit from annual adjustment and float level checks to prevent mixture drift. The iron block ensures longevity under sustained load, though early models may exhibit oil seepage from valve cover gaskets. From 1980, Fiat introduced improved EGR valve calibration and port flow (Fiat SIB 80-ME-06), reducing hot-start issues and improving idle stability in later units.
Oil Specs: Requires SAE 10W-40 mineral oil meeting API SE/CC (Fiat SIB 80-ME-06). Modern synthetic oils not advised without seal compatibility check.
Emissions: All C6.000 models comply with ECE R15 Phase II (VCA Type Approval #VCA/ECE/15/IT/842). No Phase I variants were produced.
Power Ratings: Measured under ISO 1585 standards. 92 kW output applies to Super/Elite trims with optimized ignition timing and intake tuning (Fiat TIS Doc. M132-ENG-03).

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.
Locate the engine code stamped horizontally on the front-left side of the cylinder block near the timing cover (Fiat TIS M132-ENG-03). The 8th VIN digit indicates engine type ('C' for C6.000 series). Pre-1980 models have chrome valve covers with ribbed design; post-1980 units use black-painted covers. Critical differentiation from four-cylinder units: C6.000 has inline-six configuration with longer engine bay footprint and uses Weber 36 DOHC carburettor. Service parts require model-year verification—EGR valves and oil pump drives differ pre- and post-1980 revisions (Fiat SIB 80-ME-06).
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.
