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 — ca…
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 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.
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.
Analysis derived from Fiat technical bulletins (1991-1998) and UK DVSA failure statistics (1995-2005). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The 8140.47 is fundamentally robust and known for longevity in commercial use, provided it is meticulously maintained. Its main weakness is susceptibility to cylinder head cracking if overheated. With strict adherence to cooling system maintenance and using correct oil, these engines can reliably exceed 300,000 km.
The most critical issue is cylinder head cracking between cylinders 2 and 3. Other common problems include Bosch VE injection pump failures, turbocharger wear, and glow plug system faults. These are well-documented in Fiat service bulletins and workshop manuals.
This engine was primarily used in the Fiat Ducato van (1991-1998) and the Fiat Ulysse MPV (1994-1998). Due to platform sharing, it also powered the Citroën Jumper and Peugeot Boxer vans of the same era, all badged as the 2.5 TD.
Minor power gains are possible by adjusting the Bosch VE pump's maximum fuel screw, but this is not recommended. The engine and turbo were not designed for significant extra stress. Over-fueling increases heat and soot, accelerating wear on the head, turbo, and injectors, often leading to premature failure.
Fuel economy is moderate for its era and purpose. In a Ducato van, expect around 9.5-11.0 L/100km (25-28 mpg UK) combined, depending heavily on load and driving conditions. Highway cruising can yield slightly better figures, while city driving with a heavy load will be worse.
No. The Fiat 8140.47 is a non-interference engine. If the timing chain were to fail, the pistons and valves would not collide, preventing catastrophic internal damage. This is a design feature of many older, simpler diesel engines.
Fiat recommends a 15W-40 mineral or semi-synthetic oil meeting ACEA B3/B4 or API CD/CE specifications. High-quality oil is essential for protecting the turbocharger bearings and managing soot. Change intervals should be 10,000 km or 6 months, whichever comes first.
