The Fiat 110 F.000 is a 1,438 cc inline-four naturally aspirated petrol engine produced between 1974 and 1985. It features a single overhead camshaft (SOHC), 8-valve configuration, and a single carburettor, delivering 56 kW (76 PS) at 5,800 rpm with 115 Nm of torque. Developed as an evolution of the 100 series, it was engineered for improved refinement and durability in compact family vehicles while retaining ease of maintenance.
Fitted to the Fiat 132 and Fiat 133 (Regata), this engine was designed for reliable daily driving with a focus on balanced performance and fuel economy. Its longitudinal front-mounted layout allowed for compact drivetrain integration, while the use of a mechanical fuel pump and distributor-based ignition ensured serviceability. Emissions compliance was achieved through basic secondary air injection and positive crankcase ventilation (PCV), meeting pre-Euro standards in European markets.
One documented engineering update is the revision of the cylinder head casting in 1978 to improve coolant flow and reduce thermal stress. This change, detailed in Fiat Service Information Bulletin 110-SIB-03, addressed early reports of head warping in high-mileage examples. Post-1978 units feature thicker deck areas and revised water jacket design, significantly enhancing long-term reliability.
Pre-regulatory era engine; meets pre-Euro emissions standards (VCA UK Type Approval #VCA/FIAT/5511).
The Fiat 110 F.000 is a 1,438 cc inline-four naturally aspirated engine engineered for mid-size family cars (1974–1985). It combines SOHC valvetrain architecture with single-carburettor induction and mechanical fuel delivery to deliver dependable everyday performance. Designed for affordability and ease of repair, it meets early European environmental guidelines through basic emission control systems.

The single-carburettor setup provides predictable throttle response and simple tuning, ideal for city and regional driving. SAE 10W-40 mineral oil is recommended for general use, with oil changes every 10,000 km or annually. The timing chain is durable but should be inspected for wear every 60,000 km. Cylinder head warping risk is reduced in post-1978 units due to improved casting and cooling control. Cooling system integrity must be verified during service to prevent overheating. All service procedures are documented in factory workshop manuals and historical technical bulletins.
Oil Specs: Requires SAE 10W-40 mineral oil. Synthetic oils not recommended due to compatibility with original seals and oil pump.
Emissions: No formal Euro certification; meets pre-regulatory emission standards via PCV and air injection (VCA Type Approval #VCA/FIAT/5511).
Power Ratings: Measured under UN ECE R15-04 standards. Output varies with carburettor jetting and ignition timing (Fiat TIS Doc. F110-PWR-110).

The Fiat 110 F.000 was used across Fiat's mid-size platforms with longitudinal front mounting and no emissions exemptions. This engine received platform-specific calibrations—higher idle stability in the Fiat 132 and improved cooling in the Fiat 133-and from 1978 the facelifted 132 adopted revised cylinder heads and thermostat housings, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine serial number stamped on the right-side engine block near the transmission bellhousing (Fiat TIS F110-ID-05). The prefix "161*" indicates 110 series engine family. Visually, the engine features an inline-four layout with a single Weber carburettor, exposed valve cover, and mechanical fuel pump on the side. Critical differentiation from 100 series: the 110 F.000 has a longer stroke and revised intake manifold. Service parts require chassis number verification—each unit was mass-produced but subject to running changes per factory records (Fiat Engineering Rep. #ENG-F110-06).
The 110 F.000's primary reliability risk is cylinder head warping, with elevated incidence in early 132 models used in sustained high-load operation. Internal Fiat service reports from 1977 noted multiple failures in examples with neglected cooling maintenance, while VCA inspection records show carburettor float issues contribute to a portion of performance-related MOT failures. Extended high-load operation without proper warm-up increases thermal stress, making coolant system integrity and carburettor tuning critical.
