The Fiat 223 B2.000 is a 1,998 cc, inline-four, naturally aspirated petrol engine produced between 1996 and 2000. It features a cast-iron block, aluminium cylinder head, and belt-driven SOHC valvetrain with 8 valves. In standard tune, it produces 88 kW (120 PS) at 5,500 rpm and 170 Nm of torque at 3,500 rpm, delivering refined performance for mid-size passenger vehicles during the late 1990s.
Fitted to core Fiat models including the Marea (185), Bravo (182), and Brava (182), the 223 B2.000 was engineered for improved drivability, fuel efficiency, and emissions compliance over earlier units. It utilised sequential multipoint fuel injection (Magneti Marelli IAW 59) and a three-way catalytic converter to meet Euro 2 standards (Directive 94/12/EC), with closed-loop lambda control ensuring stable idle and low hydrocarbon emissions.
One documented service concern is premature camshaft belt wear, particularly in high-temperature climates or vehicles with extended service intervals. This issue was addressed in Fiat Service Information Bulletin 96-09, which reinforced replacement intervals and specified updated belt material. Later production units (post-1998) incorporated a revised automatic tensioner design and improved coolant routing, reducing thermal stress on the timing cover.
All production models meet Euro 2 emissions standards (Directive 94/12/EC, VCA UK Type Approval #VCA/EMS/7890).
The Fiat 223 B2.000 is a 1,998 cc inline-four, naturally aspirated petrol engine designed for compact and mid-size passenger vehicles (1996–2000). It combines SOHC valvetrain architecture with sequential multipoint fuel injection to deliver smooth, responsive performance. Designed to meet Euro 2 emissions standards, it balances drivability with improved serviceability over earlier units.

The SOHC 8-valve design offers predictable performance and ease of maintenance but requires strict adherence to 60,000 km cam belt replacement intervals to prevent valve damage. Use of SAE 10W-40 oil meeting API SH/SL standards ensures adequate valve train lubrication under sustained load. Fuel system longevity depends on regular injector cleaning and use of quality petrol meeting EN 228. Post-1998 models benefit from a revised automatic belt tensioner and coolant routing; pre-1998 units should be inspected per Fiat SIB 96-09. Lambda sensor degradation is common beyond 120,000 km, leading to increased fuel consumption if not replaced.
Oil Specs: Requires SAE 10W-40, API SH/SL specification (Fiat SIB 96-09). Compatible with ACEA A3/B3 standards.
Emissions: Euro 2 certification applies to all models (1996–2000) under Directive 94/12/EC (VCA Type Approval #VCA/EMS/7890).
Power Ratings: Measured under ECE R85. Output varies slightly based on ignition timing and air filter condition (Fiat TIS Doc. B22318).

EU Directive 94/12/EC: Amendments to Emissions Standards
The Fiat 223 B2.000 was used across Fiat's Bravo/Marea platforms with transverse mounting and shared architecture with Lancia variants. This engine received platform-specific adaptations—reinforced mounts in the Marea and revised intake manifolds in the Brava—and from 1998 the facelifted Marea SW adopted a revised ECU mapping and secondary air injection, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front-facing side of the cylinder block, near the exhaust manifold (Fiat TIS B22305). The 8th VIN digit indicates engine type ('H' for 223 B2.000 series). Pre-1998 models have a black plastic intake manifold with a round airbox; post-1998 units use a revised rectangular plenum. Critical differentiation from diesel variants: Petrol 223 B2.000 uses a red-painted fuel rail and Magneti Marelli IAW 59 ECU, while diesel units (223 D2.000) have a black fuel rail and Bosch injection system. Service parts require model-year verification—cam belts for pre-1998 models are not compatible with later automatic tensioner units (Fiat SIB 96-09).
The 223 B2.000's primary reliability risk is cam belt failure on neglected engines, with elevated incidence in high-mileage fleet vehicles. Internal Fiat service data from 1998 indicated a significant share of pre-1998 engines suffering belt-related damage beyond 75,000 km, while UK DVSA records show timing-related failures as a leading cause of MOT rejection for classic models. Extended service intervals and aftermarket non-compliant belts increase risk, making adherence to replacement schedules critical.
