The Fiat 182 B4.000 – Petrol is a 1,372 cc, inline-four, naturally aspirated engine produced between 1996 and 2001. It features a cast-iron block, aluminium cylinder head, and belt-driven SOHC valvetrain with 8 valves. In standard configuration, it delivers 50 kW (68 PS) at 5,500 rpm and 104 Nm of torque at 2,750 rpm, offering reliable low-end responsiveness for urban and compact applications.
Fitted to models such as the Fiat Bravo (182), Fiat Brava (182), and Fiat Marea (185), the 182 B4.000 was engineered for balanced drivability and emissions compliance. Emissions control is achieved via a catalytic converter and lambda sensor, meeting Euro 2 standards across all markets from 1997 onward.
One documented update is the introduction of a revised intake manifold and ECU mapping in 1998, improving volumetric efficiency and idle stability. This improvement, detailed in Fiat Service Information Bulletin 97-12, also reduced hydrocarbon emissions. From 1999 onward, Fiat introduced a modified valve stem seal design and updated timing belt tensioner, enhancing long-term reliability under sustained loads.
All units produced from 1997–2001 comply with Euro 2 emissions standards (VCA UK Type Approval #VCA/EMS/7893). Pre-1997 models meet Euro 1 benchmarks.
The Fiat 182 B4.000 – Petrol is a 1,372 cc inline-four naturally aspirated engine designed for compact and mid-size vehicles (1996–2001). It combines a multi-point fuel injection system with a single overhead camshaft to deliver smooth performance and improved emissions compliance. Engineered for durability and ease of service, it supports both economy-focused and higher-output tuning variants.

The fuel injection system provides reliable low-RPM torque ideal for city driving, but requires strict adherence to 60,000 km or 4-year cam belt replacement intervals to prevent interference damage. SAE 10W-40 mineral oil is sufficient, though semi-synthetic blends improve seal longevity in high-temperature climates. Fuel-injected models offer better cold-start reliability and idle stability compared to carburetted predecessors. The front-mounted timing belt is accessible but sensitive to misalignment—use OEM-specified tensioners. Post-1999 models feature improved belt materials and tensioner geometry, reducing slippage risks. Emissions systems require lead-free fuel to avoid catalyst poisoning.
Oil Specs: Requires SAE 10W-40 API SG/CD specification (Fiat SIB 97-12). No BMW Longlife or ACEA standards apply.
Emissions: Euro 2 compliance confirmed for 1997–2001 models (VCA Type Approval #VCA/EMS/7893). Pre-1997 units meet Euro 1 standards.
Power Ratings: Measured under ISO 1585. Output consistent across fuel grades RON 91–98 (Fiat TIS Doc. A18410).

The Fiat 182 B4.000 – Petrol was used across Fiat's 182-series and 185-series platforms with transverse mounting and shared architecture with Lancia derivatives in select European markets. This engine received platform-specific adaptations-shorter intake manifolds in the Bravo and revised cooling routing in the Marea-and from 1997 the facelifted Brava incorporated a catalytic converter and lambda sensor, creating emissions-based interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the left-side engine block near the transmission bellhousing (Fiat TIS A18490). The 8th VIN digit indicates engine type ('D' for 182 B4.000). Pre-1999 models have chrome valve covers with ribbed timing covers; post-1999 units use black plastic covers. Critical differentiation from 149-series: 182 B4.000 has fuel injection, higher compression (9.4:1), and revised intake. Service parts require model-year verification—timing belts for pre-1999 engines are incompatible with post-1999 revisions due to pulley diameter and tensioner changes (Fiat SIB 97-12).
The 182 B4.000 – Petrol's primary reliability risk is timing belt failure on pre-1999 units, with elevated incidence in high-temperature climates. Internal Fiat quality reports from 1998 indicated a significant number of engines suffering valve damage due to belt slippage, while VCA field data links a portion of pre-2001 MOT failures to idle instability and ECU faults. Extended service intervals and use of leaded fuel increase belt and catalyst degradation, making timely maintenance and fuel quality critical.
