The Fiat 8140.47 is a 2,445 cc, inline‑four turbo‑diesel engine produced between 1991 and 1998. It features indirect injection, a fixed-geometry turbocharger, and a single overhead camshaft (SOHC) design. In standard form, it delivered approximately 85 kW (116 PS) and 270 Nm of torque, providing robust low-end pulling power for commercial applications.
Fitted primarily to the Ducato van (Type 244) and Ulysse MPV, the 8140.47 was engineered for durability and load-carrying capability in light commercial and fleet use. Emissions compliance for its era was managed through basic engine calibration and the absence of complex after-treatment systems, meeting Euro 1 standards.
A documented concern is cylinder head cracking, particularly between cylinders 2 and 3, often exacerbated by overheating or coolant neglect. This issue, referenced in Fiat Technical Service Bulletin TSB‑8140‑01, is typically linked to thermal stress from inadequate cooling system maintenance or thermostat failure.
Production years 1991–1998 meet Euro 1 standards (VCA UK Type Approval #VCA/EMS/5678).
The Fiat 8140.47 is a 2,445 cc inline‑four turbo‑diesel engineered for light commercial vehicles and MPVs (1991-1998). It combines indirect fuel injection with a fixed-geometry turbocharger to deliver strong low‑end torque and rugged reliability. Designed to meet Euro 1 standards, it prioritizes durability and serviceability for high-mileage use.

The fixed-geometry turbo provides predictable, lag-free torque ideal for heavy loads but demands vigilant cooling system upkeep to prevent head gasket or cylinder head failure. ACEA B3/B4 15W-40 oil is critical for its high-temperature stability and soot handling. Coolant should be replaced every 2 years regardless of mileage to prevent corrosion and overheating. The Bosch VE pump is robust but sensitive to water-contaminated fuel; use only high-quality diesel with effective water separators. Cylinder head cracking, addressed in TSB TSB-8140-01, is a known risk if the engine is allowed to overheat.
Oil Specs: Requires ACEA B3/B4 specification (Fiat SIB TSB-8140-01). API CD/CE is also acceptable.
Emissions: Euro 1 certification applies to all 1991–1998 models (VCA Type Approval #VCA/EMS/5678).
Power Ratings: Measured under EEC 80/1269 standards. Output is consistent across verified applications (Fiat PT-1995).

The Fiat 8140.47 was used across Fiat's light commercial platforms with longitudinal mounting. This engine received platform-specific adaptations-minor ECU mapping differences for the Ulysse versus the Ducato-creating no significant interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on a flat boss on the front left side of the engine block, near the injection pump (Fiat Workshop Manual 8140). The 8th digit of the VIN typically corresponds to the engine code for Fiat Professional vehicles. Visually, it is identifiable by its cast-iron block, SOHC valve cover, and the prominent Bosch VE injection pump mounted on the right side. Critical differentiation from the non-turbo 8140.43: The .47 has a turbocharger and associated plumbing; the .43 does not. Service parts for the cylinder head require verification against the specific casting number due to mid-production revisions.
The 8140.47's primary reliability risk is cylinder head cracking, with elevated incidence in vehicles subjected to heavy loads or neglected cooling systems. Fiat internal service data indicates this was a leading cause of major engine repairs for this model, while its simple design otherwise offers good longevity. Maintaining coolant quality and preventing overheating are critical.
