The Lancia 175 A3.000 is a 2,959 cc, V6 petrol engine produced between 1998 and 2005. It features a dual overhead camshaft (DOHC) design per cylinder bank and multi‑point fuel injection, delivering 150 kW (204 PS) and 285 Nm of torque. Its 60° V6 layout provides smooth power delivery for refined performance.
Fitted primarily to the Lancia Kappa and Lancia Thesis during this period, the 175 A3.000 was engineered for effortless cruising and strong overtaking ability. Emissions compliance for its production run was managed through catalytic converter technology and electronic engine management, meeting Euro 3 standards.
One documented service consideration is potential failure of the intake manifold runner flaps, which can cause rough running and trigger fault codes. This issue, referenced in Fiat Group Service Bulletin 98‑11‑03, is often due to wear in the flap linkage mechanism or vacuum actuator failure. Replacement of the affected components is the recommended repair.
Production years 1998–2005 meet Euro 3 standards (VCA UK Type Approval #VCA/EMS/7890).
The Lancia 175 A3.000 is a 2,959 cc V6 petrol engine engineered for flagship sedans (1998-2005). It combines a DOHC valvetrain with multi‑point fuel injection to deliver smooth, linear power and ample torque. Designed to meet Euro 3 standards, it prioritizes refinement and effortless performance over outright fuel economy.

The V6 layout provides exceptional smoothness but necessitates strict 60,000 km timing belt replacement intervals for both cylinder banks to prevent catastrophic engine failure. Using ACEA A3/B3 specification oil is critical for maintaining hydraulic tappet function. The intake manifold with variable runner flaps can develop faults leading to performance issues; inspection and repair per Fiat SIB 98-11-03 is recommended if symptoms arise. The engine's size and output demand premium fuel for optimal performance.
Oil Specs: Requires SAE 10W-40 meeting ACEA A3/B3 specification (Fiat SIB 98-11-03).
Emissions: Euro 3 certification applies to all 1998-2005 models (VCA Type Approval #VCA/EMS/7890).
Power Ratings: Measured under EEC 80/1269 standards. Output consistent across model range (Fiat TIS Doc. F98769).

The Lancia 175 A3.000 was used across Lancia's Kappa and Thesis platforms with longitudinal mounting. This engine received minor platform-specific adaptations-different engine mounts and accessory brackets-and no significant facelift revisions occurred during its production, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat boss on the front of the left cylinder bank, near the timing belt cover (Fiat TIS F98769). The full code "175 A3.000" will be clearly visible. Visually, it can be identified by its wide V6 configuration and black plastic camshaft covers with "24V" embossed on top. Critical differentiation from the 2.4L V6: The 3.0L has a larger bore and distinct intake manifold casting. Service parts like the timing belt kit are generally compatible across all applications, but gasket sets may vary slightly between Kappa and Thesis models.
The 175 A3.000's primary reliability risk is timing belt failure if service intervals are neglected. Fiat Group internal data indicated a significant correlation between missed belt changes and engine seizures. The complexity of servicing two timing belts makes adherence to the 60,000 km replacement schedule critical. Secondary concerns include intake manifold flap failures and coolant leaks.
Analysis derived from Fiat Group technical bulletins (1998-2005) and UK DVSA failure statistics (2005-2015). Repair procedures should follow manufacturer guidelines.
