The Lancia 188 A5.000 is a 1,995 cc, inline‑four petrol engine produced between 1990 and 1995. It features a twin‑cam (DOHC) design and multi‑point electronic fuel injection, delivering refined power delivery and improved emissions for its era. The aluminium alloy block and head construction maintained a favorable power-to-weight ratio for agile handling.
Fitted primarily to the Lancia Dedra Integrale and Thema 8.32, the 188 A5.000 was engineered for spirited performance and responsive driving. Emissions compliance for its production period was achieved through precise electronic fuel injection and catalytic converter integration, aligning with Euro 1 standards.
One documented engineering concern is premature wear of the hydraulic valve lifters, which could lead to audible tappet noise and reduced valve clearance. This was addressed in Lancia service documentation, recommending specific lifter replacement procedures and the use of approved oil formulations to mitigate wear.
Production years 1990–1995 meet Euro 1 standards (Italian Ministry of Transport Type Approval).
The Lancia 188 A5.000 is a 1,995 cc inline‑four petrol engine engineered for performance sedans (1990-1995). It combines dual overhead camshafts with multi-point electronic fuel injection to deliver smooth, linear power and meet emissions targets. Designed to meet Euro 1 standards, it balances performance with regulatory compliance.

The DOHC 16-valve design provides smooth, high-revving power ideal for spirited driving but demands strict adherence to the 60,000 km timing belt replacement interval to prevent catastrophic engine failure. SAE 10W-40 mineral oil is specified for its balance of protection and flow. The documented hydraulic lifter wear issue necessitates using the approved oil specification and replacing lifters as a set if noise develops, per Lancia service procedures.
Oil Specs: Requires SAE 10W-40 mineral oil specification (Lancia Owner's Manual, Dedra Integrale 1991). Modern synthetic equivalents meeting API SG/CD or earlier are often used.
Emissions: Euro 1 certification applies to all 1990-1995 models (Italian Ministry of Transport Type Approval).
Power Ratings: Measured under period-typical standards (e.g., DIN 70020). Figures are net power as installed in vehicle (Lancia Type Approval Documentation 1990).

The Lancia 188 A5.000 was used across Lancia's Dedra and Thema platforms with longitudinal, front-engine, front-wheel-drive mounting. This engine received minor platform-specific adaptations for ancillary drive layouts and engine management harness routing. All adaptations are documented in OEM technical bulletins.
Locate the engine type code stamped on a flat boss on the cylinder block, typically near the oil filter or on the front face adjacent to the water pump (Lancia Workshop Manual 835). The code "188 A5.000" should be clearly visible. Visually, it is identifiable by its twin camshaft covers and the multi-point fuel injection rail on the intake manifold. Differentiation from the 8-valve engines is by the valve cover design and the number of intake runners. Service parts for the hydraulic lifters require verification of the correct part number as per Lancia Technical Bulletin.
The 188 A5.000's primary reliability risk is hydraulic lifter wear, leading to noise and potential valve train issues if neglected. Lancia service data indicates this was a prevalent concern in high-mileage examples, particularly those using incorrect oil specifications. Adherence to the specified oil type and timely lifter replacement is critical to prevent long-term damage.
