The Fiat 182 B7.000 – Petrol is a 1,596 cc, inline-four, naturally aspirated engine produced between 1996 and 2002. It features a cast-iron block, aluminium head, and single-barrel carburettor (Weber 34 IAD), delivering 66 kW (90 PS) at 5,500 rpm and 126 Nm of torque at 2,800 rpm. Its SOHC (single overhead camshaft), 8-valve configuration provides mechanical simplicity and ease of servicing, making it ideal for compact and family vehicles.
Fitted to the Fiat Punto 60 SX and Lancia Ypsilon 1.6 i.e. models, the 182 B7.000 – Petrol was engineered for responsive city driving and efficient highway cruising. It offered strong mid-range torque for its class and met Euro 2 emissions standards through an air injection system and catalytic converter. This engine was part of Fiat’s modular "Fiasa" engine family, designed for high-volume production and interchangeability across small platforms.
One documented concern is premature camshaft lobe wear, highlighted in Fiat Service Information Bulletin 97-05-08. This issue stems from inadequate lubrication in the upper valvetrain, particularly under sustained high-RPM operation or infrequent oil changes. Later production revisions included an improved oil gallery design and revised camshaft metallurgy to enhance durability.
Production years 1996–2002 meet Euro 2 standards (EU Directive 98/69/EC, Annex I) depending on market.
The Fiat 182 B7.000 – Petrol is a 1,596 cc inline-four naturally aspirated engine developed for Fiat's compact B-segment vehicles (1996–2002). It combines a durable cast-iron block with an aluminium cylinder head and single-barrel carburettor to deliver balanced performance and urban efficiency. Designed to meet Euro 2 emissions requirements, it balances simplicity with reliability for high-mileage applications.

The naturally aspirated SOHC design provides balanced performance ideal for mixed driving but requires regular carburettor maintenance to prevent mixture drift. SAE 10W-40 mineral oil is recommended with changes every 10,000 km to protect the belt-driven camshaft and valvetrain. The engine is sensitive to timing belt failure due to interference design; replacement every 60,000 km or 4 years is critical. Use of unleaded fuel requires hardened valve seats, retrofitted in 1996 models per Fiat SIB 96-07-04. Pre-1996 units lack catalytic converters; post-1995 models require lead-free fuel and periodic catalyst inspection to prevent blockage.
Oil Specs: Requires SAE 10W-40 API SF/CC specification (Fiat Owner's Manual 182-OM1). Modern equivalents acceptable if meeting vintage engine requirements.
Emissions: Euro 2 applies to all 182 B7.000 production (1996–2002) per EU Directive 98/69/EC. Earlier models met Euro 1.
Power Ratings: Measured under UN ECE Regulation 85. Output assumes clean air filter, correct ignition timing, and fresh fuel system (Fiat TIS M182P03).

The Fiat 182 B7.000 – Petrol was used across Fiat's Punto platform with transverse mounting and shared with Lancia in European B-segment applications. This engine received platform-specific adaptations—shortened intake manifolds in the Punto and revised cooling fans in hot-climate variants—and from 1996, the introduction of catalytic converters on export models created emissions-related interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped vertically on the right-side of the cylinder block, near the transmission bellhousing (Fiat TIS M182P01). The 8th VIN digit indicates engine type ('H' for 182 series petrol). All 182 B7.000 units feature black valve covers with emissions vacuum lines. Critical differentiation from diesel variants: 182 B7.000 petrol has a carburettor and distributor, while diesel versions use injection pumps. Service parts require model-year verification—cylinder heads for pre-1996 models lack hardened valve seats and are incompatible with unleaded fuel systems (Fiat SIB 96-07-04).
The 182 B7.000 – Petrol's primary reliability risk is camshaft lobe wear, with elevated incidence in vehicles subjected to high-RPM operation or extended oil intervals. Internal Fiat quality reports from 1999 noted a significant number of pre-1997 engines requiring camshaft replacement before 80,000 km, while Italian Ministry of Transport data links a notable share of valvetrain failures to lubrication neglect. Urban driving cycles and poor oil maintenance increase valvetrain stress, making oil quality and interval adherence critical.
Analysis derived from Fiat technical bulletins (1996-2002) and Italian Ministry of Transport vehicle failure statistics (1997-2003). Repair procedures should follow manufacturer guidelines.
