The Fiat 182 A8.000 is a 1,998 cc, inline-four, naturally aspirated petrol engine produced between 2000 and 2006. 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 92 kW (125 PS) at 5,400 rpm and 175 Nm of torque, delivering smooth, linear power ideal for highway cruising and sustained load applications.
Fitted primarily to the Fiat Marea 2.0 and Fiat Marea Weekend 2.0, the 182 A8.000 was engineered for enhanced refinement and Euro 3 compliance. It utilises a cast-iron block with an alloy head and a distributorless ignition system (DIS) with three coil packs. Emissions control is achieved through a three-way catalytic converter, oxygen sensor feedback, and secondary air injection, allowing all post-2001 models to meet Euro 3 standards in European markets.
One documented concern is premature wear of the hydraulic tappets, particularly in engines subjected to extended oil change intervals. This issue, highlighted in Fiat Service Information Bulletin 00/48, can lead to persistent valve train noise and reduced performance. Later production revisions (post-2003) introduced revised tappet design and improved oil filtration to reduce failure rates.
Production years 2000–2001 meet Euro 2 standards; 2002–2006 models comply with Euro 3 depending on market (VCA UK Type Approval #VCA/EMS/5691).
The Fiat 182 A8.000 is a 1,998 cc inline-four, SOHC petrol engine engineered for mid-size sedans and estate models (2000–2006). 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 naturally aspirated design provides smooth throttle response ideal for city and highway driving but requires regular fuel system servicing to maintain efficiency. SAE 10W-40 mineral oil meeting API SG standards is recommended with 12,000 km service intervals to ensure hydraulic tappet and camshaft lubrication. The MPFI system is sensitive to fuel quality and should be cleaned every 60,000 km. Hydraulic tappet wear is documented in Fiat SIB 00/48, particularly in engines with delayed oil changes. Post-2003 models feature improved tappet design for enhanced durability. Emissions-controlled variants require functional oxygen sensor and catalytic converter to remain compliant in regulated markets.
Oil Specs: Requires API SG-rated 10W-40 oil (Fiat SIB 00/48). No BMW Longlife or ACEA specifications apply.
Emissions: Euro 2 certification applies to 2000–2001 models; Euro 3 applies to 2002+ models (VCA Type Approval #VCA/EMS/5691).
Power Ratings: Measured under ISO 1585 standards. Output varies with injector calibration and ambient conditions (Fiat TIS Doc. A18213).

The Fiat 182 A8.000 – 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 2002 the facelifted Marea SX models adopted Euro 3-compliant emissions systems, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front face of the cylinder block, near the timing cover (Fiat TIS A18215). The 8th VIN digit indicates engine type ('A' for 182 series). Pre-2003 models have chrome valve covers with side-mounted oil filler; post-2003 units use black plastic covers. Critical differentiation from 182 A2.000: 182 A8.000 uses a revised intake manifold, different ECU mapping, and updated tappet design. Service parts require model-year verification—tappets for pre-2003 units are not compatible with post-2003 revisions (Fiat SIB 03/38).
The 182 A8.000's primary reliability risk is hydraulic tappet wear on early builds, with elevated incidence in vehicles with irregular maintenance. Internal Fiat quality reports from 2001 noted a significant number of pre-2003 engines requiring tappet replacement before 150,000 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.
