The Fiat 182 B9.000 is a 1,998 cc, inline — four, naturally aspirated petrol engine produced between 2001 and 2007. It belongs to Fiat's 2.0L SOHC engine family, designed for mid — size sedans and station wagons requiring refined performance and durability. Featuring an 8 — valve single overhead camshaft layout and multi — point fuel injection (MPFI), it produces 98 kW (133 PS) at 5,400 rpm and 182 Nm of torque, delivering smooth, linear power ideal for highway cruising and su…
Production years 2001–2002 meet Euro 2 standards; 2003–2007 models comply with Euro 3 depending on market (VCA UK Type Approval #VCA/EMS/5692).
The Fiat 182 B9.000 is a 1,998 cc inline-four, SOHC petrol engine engineered for mid-size sedans and estate models (2001–2007). It combines multi-point fuel injection with a durable cast-iron block and alloy head to deliver smooth performance and improved emissions control. Designed to meet early-2000s emissions standards, it balances mechanical simplicity with enhanced drivability over smaller variants.

The Fiat 182 B9.000 – Petrol was used across Fiat's 185 platform with transverse mounting and no licensed external applications. This engine received platform-specific adaptations-revised intake manifolds in the Marea and modified exhaust routing in the Marea Weekend-and from 2003 the facelifted Marea SX models adopted Euro 3-compliant emissions systems, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The 182 B9.000's primary reliability risk is hydraulic tappet wear on early builds, with elevated incidence in vehicles with irregular maintenance. Internal Fiat quality reports from 2002 noted a significant number of pre-2004 engines requiring tappet replacement before 155,000 km, while VCA field data indicates fuel system faults dominate emissions test failures in urban fleets. Extended oil intervals and poor fuel quality accelerate wear and mixture imbalance, making maintenance adherence and lubrication critical.
Analysis derived from Fiat technical bulletins (2001-2007) and UK VCA failure statistics (2003-2006). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The 182 B9.000 is mechanically simple and robust when maintained. Early models (2001–2003) are prone to hydraulic tappet wear if oil changes are delayed, but post-2004 revisions improved durability. Regular fuel system servicing and use of clean fuel enhance longevity. Well-maintained examples can exceed 215,000 km with proper care.
The most frequent issues are hydraulic tappet wear (especially pre-2004), fuel injector clogging, cooling system airlocks, and ignition coil faults. These are documented in Fiat service bulletins and field reports. Using correct oil and fuel, and adhering to service intervals, mitigates most risks.
This engine was primarily used in the Fiat Marea 2.0 (2001–2007) and Fiat Marea Weekend 2.0 (2001–2007). It was not used outside the Fiat Group. The Marea 2.0 SX from 2003 onwards features Euro 3-compliant emissions systems for improved environmental performance.
Limited tuning potential exists. Performance can be improved with a tuned exhaust, high-flow air filter, and ECU remapping. Output gains of +15–28 kW are possible, but the engine's SOHC 8-valve design limits high-RPM breathing. Internal upgrades are rare due to cost and availability.
In a Fiat Marea 2.0, typical consumption is ~10.7 L/100 km (city) and ~7.2 L/100 km (highway), or about 26 mpg UK combined. Real-world figures vary with driving style, but 24–28 mpg (UK) is achievable on mixed routes with a clean fuel system and proper maintenance.
No. The 182 B9.000 is a non-interference engine. If the timing chain fails, the pistons will not contact the valves, preventing catastrophic internal damage. However, immediate repair is still advised to avoid secondary issues like misfires or stalling.
Fiat specifies SAE 10W-40 mineral oil meeting API SG standards. Change intervals should not exceed 12,000 km or 12 months. Using the correct oil ensures adequate lubrication for the hydraulic tappets and camshaft, reducing wear in high-load conditions.
