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 (…
All units produced from 1997–2001 comply with Euro 2 emissions standards . 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 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.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 182 B4.000 – Petrol is mechanically simple and durable when maintained. Early models (1996–1998) are at risk of timing belt failure, but post-1999 revisions improved belt and tensioner design. Engines with documented service history and regular belt changes can exceed 150,000 km. Use of correct oil and unleaded fuel is essential for longevity.
The most frequent issues are timing belt failure (especially pre-1999), idle instability due to IACV or throttle body carbon buildup, valve stem seal leaks, and cooling system airlocks. These are documented in Fiat service bulletins. The fuel injection system requires periodic cleaning, and the front-mounted belt must be replaced every 60,000 km to prevent engine damage.
This 1.4L petrol engine was used in the Fiat Bravo 1.4 SX (1996–2001), Fiat Brava 1.4 SX (1996–2001), and Fiat Marea 1.4 SX (1997–2001). All applications were front-wheel drive with transverse engine mounting and 5-speed manual transmission.
Aftermarket ECU tuning is common on the 182-B4-000 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In real-world driving, expect 7.0–8.5 L/100km (40–33 mpg UK). The Fiat Bravo 1.4 achieves ~7.5 L/100km (38 mpg UK) combined. Fuel economy depends heavily on driving style and condition of the fuel injection system. Regular maintenance ensures optimal efficiency.
Yes. The 182 B4.000 – Petrol is an interference engine. If the timing belt breaks or slips, the pistons can strike the open valves, causing severe internal damage. This makes strict adherence to the 60,000 km belt replacement interval absolutely critical.
Fiat specifies SAE 10W-40 mineral oil meeting API SG/CD standards. Change oil every 15,000 km or annually. While modern semi-synthetics can be used, avoid high-detergent oils that may degrade older seals. Proper lubrication supports timing belt and camshaft longevity.
