FIAT 182-A2-000 engine (1999–2005) – Specs, Problems & Compatibility Database

The Fiat 182 A2.000 is a 1,998 cc, inline-four, naturally aspirated petrol engine produced between 1999 and 2005. It belongs to Fiat's 2.0L SOHC engine family, designed for mid-size sedans and station wagons requiring smooth performance and improved emissions control. Featuring an 8-valve single overhead camshaft layout and multi-point fuel injection (MPFI), it produces 88 kW (120 PS) at 5,400 rpm and 170 Nm of torque, delivering refined drivability with strong low-end pull for urban and highway use.

Fitted primarily to the Fiat Marea 2.0 and Fiat Marea Weekend 2.0, the 182 A2.000 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 compliance is achieved through a catalytic converter, oxygen sensor feedback, and secondary air injection, allowing all post-2000 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 99/45, can lead to persistent valve train noise and reduced performance. Later production revisions (post-2002) introduced revised tappet design and improved oil filtration to reduce failure rates.

Compliance Note:

Production years 1999–2000 meet Euro 2 standards; 2001–2005 models comply with Euro 3 (VCA UK Type Approval #VCA/EMS/5690).

182-A2-000 Technical Specifications

The Fiat 182 A2.000 is a 1,998 cc inline-four, SOHC petrol engine engineered for mid-size sedans and estate models (1999–2005). 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 late-1990s to early-2000s emissions standards, it balances mechanical simplicity with enhanced drivability over smaller variants.

Practical Implications

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 99/45, particularly in engines with delayed oil changes. Post-2002 models feature improved tappet design for enhanced durability. Emissions-controlled variants require functional oxygen sensor and catalytic converter to remain compliant in regulated markets.

Data Verification Notes

Oil Specs: Requires API SG-rated 10W-40 oil (Fiat SIB 99/45). No BMW Longlife or ACEA specifications apply.

Emissions: Euro 2 certification applies to 1999–2000 models; Euro 3 applies to 2001+ models (VCA Type Approval #VCA/EMS/5690).

Power Ratings: Measured under ISO 1585 standards. Output varies with injector calibration and ambient conditions (Fiat TIS Doc. A18203).

182-A2-000 Compatible Models

The Fiat 182 A2.000 – 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 2001 the facelifted Marea SX models adopted Euro 3-compliant emissions systems, creating interchange limits. All adaptations are documented in OEM technical bulletins.

Identification Guidance

Locate the engine code stamped horizontally on the front face of the cylinder block, near the timing cover (Fiat TIS A18205). The 8th VIN digit indicates engine type ('A' for 182 series). Pre-2002 models have chrome valve covers with side-mounted oil filler; post-2002 units use black plastic covers. Critical differentiation from 170 A.046: 182 A2.000 uses a revised intake manifold, different ECU mapping, and updated tappet design. Service parts require model-year verification—tappets for pre-2002 units are not compatible with post-2002 revisions (Fiat SIB 02/35).

Identification Details

Evidence:

Fiat TIS Doc. A18205

Location:

Stamped horizontally on the front face of the cylinder block, near the timing cover (Fiat TIS A18205).

Visual Cues:

  • Pre-2002: Chrome valve cover with side oil filler
  • Post-2002: Black plastic valve cover
  • Euro 3 models: Equipped with secondary air injection and dual oxygen sensors
Compatibility Notes

Exhaust:

Pre-2001 Euro 2 exhaust manifolds are incompatible with post-2001 Euro 3 catalytic systems due to different flange and sensor ports.

Evidence:

Fiat SIB 02/35

Ignition System:

Distributorless ignition (DIS) with three coils requires correct ECU mapping; mismatched units cause misfires.
Hydraulic Tappet Wear

Issue:

Early 182 A2.000 engines (1999–2001) are prone to hydraulic tappet wear due to oil degradation and extended service intervals.

Evidence:

Fiat SIB 99/45

Recommendation:

Inspect tappets during service; replace with post-2002 upgraded-spec units if noisy or collapsed.

Common Reliability Issues - FIAT 182-A2-000

The 182 A2.000's primary reliability risk is hydraulic tappet wear on early builds, with elevated incidence in vehicles with irregular maintenance. Internal Fiat quality reports from 2000 noted a significant number of pre-2002 engines requiring tappet replacement before 145,000 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.

Hydraulic tappet wear or failure
Symptoms: Ticking or tapping noise at idle, especially on cold start, inconsistent valve clearance, reduced performance.
Cause: Wear in hydraulic tappets due to marginal oil flow or degraded oil, exacerbated by extended service intervals.
Fix: Replace all tappets with post-2002 upgraded OEM parts; flush oil system and use correct API SG 10W-40 oil.
Fuel injector clogging or imbalance
Symptoms: Rough idle, hesitation, misfiring, increased fuel consumption, check engine light.
Cause: Deposit buildup in injectors due to low-quality fuel or infrequent servicing, leading to poor atomization.
Fix: Clean or replace injectors using OEM-spec kit; perform fuel system flush and ECU adaptation reset.
Cooling system airlocks
Symptoms: Overheating despite full coolant, erratic temperature gauge, heater inefficiency.
Cause: Air trapped in the cooling circuit due to improper refill procedure or failing expansion tank cap.
Fix: Bleed system using manufacturer-recommended method; replace cap and thermostat if faulty.
Distributorless ignition system faults
Symptoms: Misfires, rough running, no-start condition, intermittent power loss.
Cause: Coil pack failure or wiring degradation in the DIS system, particularly in high-heat environments.
Fix: Test coil packs and wiring; replace faulty components with OEM-specified parts and verify ECU communication.
