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. Emissi…
Production years 1998–2005 meet Euro 3 standards .
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 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.
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 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 175 A3.000 is generally reliable if its critical timing belt service is performed punctually every 60,000 km on both cylinder banks. Neglecting this can lead to total engine failure. With proper maintenance, including addressing minor leaks and intake issues, these engines can easily surpass 200,000 km.
The most common issues are timing belt failure (if neglected), intake manifold runner flap linkage breakage, coolant leaks from the plastic thermostat housing, and oil leaks from the valve cover gaskets. These are well-documented in Fiat Group service bulletins.
This 3.0L V6 24V engine was used in the Lancia Kappa (839 series) from 1998 to 2001 and the Lancia Thesis (840 series) from 2002 to 2005. It was the flagship petrol engine for these models during that period.
Yes, but gains are modest. Simple modifications like a performance air filter and sports exhaust can yield 8-12 kW. ECU remapping is possible but offers limited gains due to the engine's naturally aspirated design. Significant power increases require internal modifications like camshafts, which are complex on a V6.
Fuel economy is typical for a 3.0L V6 of its era. Expect around 13.5 L/100km in city driving and 8.5 L/100km on the highway, translating to approximately 21 mpg UK combined. Economy is heavily influenced by driving style and vehicle weight.
Yes. The 175 A3.000 is an interference engine. If either timing belt breaks or slips, the pistons will collide with the open valves on that bank, causing severe and expensive internal engine damage. This makes the 60,000 km belt change interval for both banks absolutely critical.
Lancia specifies a 10W-40 mineral or semi-synthetic oil meeting ACEA A3/B3 standards. Using the correct viscosity and specification is vital for protecting the hydraulic tappets and ensuring proper lubrication under all operating conditions.
