The Fiat 159 A2.000 – Petrol is a 1,368 cc, inline — four, naturally aspirated engine produced between 2012 and 2018. It is part of the FIRE (Fully Integrated Robotised Engine) Evo family, featuring multi — point fuel injection (MPFI), dual overhead camshafts (DOHC), and a 16 — valve configuration. Delivering 74 kW (101 PS) and 132 Nm of torque, it was engineered for responsive urban performance and improved efficiency over earlier FIRE units.

The Fiat 159 A2.000 – Petrol is a 1,368 cc inline-four naturally aspirated engine engineered for compact and mid-size hatchbacks (2012–2018). It combines multi-point fuel injection with a 16-valve DOHC layout to deliver refined throttle response and consistent fuel efficiency. Designed to meet Euro 5 emissions standards, it balances everyday usability with cost-effective ownership and serviceability.

The Fiat 159 A2.000 – Petrol was used across Fiat's 198/199 platforms with transverse mounting and front-wheel drive. This engine received platform-specific adaptations-shorter intake manifolds in the Punto Evo and revised engine mounts in the Bravo-and from 2014 the updated tensioner design was implemented across all applications, creating service part interchange limits. 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 159 A2.000 – Petrol's primary reliability risk is timing belt tensioner wear, with elevated incidence in high-temperature or stop-start urban environments. Internal Fiat quality reports from 2015 indicated a notable number of pre-2014 engines required premature belt service due to tensioner degradation, while VCA MOT data shows timing-related failures contribute to a measurable share of engine breakdowns in city-driven examples. Extended service intervals and poor coolant maintenance increase thermal stress, making adherence to replacement schedules and coolant quality critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 159 A2.000 – Petrol is generally reliable when maintained properly, but pre-2014 models are at higher risk of timing tensioner failure. Engines with documented service history and timely belt changes (every 6 years or 120,000 km) can exceed 150,000 km. Using correct oil and coolant, and addressing small leaks promptly, significantly improves longevity.
The most frequent issues are timing belt tensioner failure (especially pre-2014), coolant leaks from the thermostat housing, idle instability due to throttle body carbon buildup, and oil seepage from the valve cover gasket. These are documented in Fiat service bulletins and supported by MOT failure data.
This engine was used in the Fiat Bravo (198, 2012–2014), Fiat Punto Evo (199, 2012–2018), and Lancia Delta (840, 2012–2014). It was marketed as the '1.4 16V 101 HP' and was phased out in favour of turbocharged FIRE units and the Global Small Engine (GSE) family.
No meaningful tuning potential exists. The engine is naturally aspirated with MPFI and no factory turbo. ECU remaps offer negligible gains. Performance modifications are impractical due to the engine's design focus on economy and cost. Replacement with a turbocharged GSE unit is possible but not a direct upgrade path.
In mixed driving, expect 6.2–7.0 L/100km (40–45 mpg UK). City driving may see 7.8 L/100km (36 mpg), while highway runs can achieve 5.6 L/100km (50 mpg). Real-world economy depends heavily on driving style and condition of the air filter and spark plugs.
Yes. The 159 A2.000 – Petrol is an interference engine. If the timing belt fails or jumps, the pistons can strike the open valves, causing severe internal damage. This makes strict adherence to the 6-year/120,000 km replacement interval absolutely critical.
Fiat specifies SAE 5W-30 oil meeting API SN/CF or ACEA A5/B5 standards. Use a high-quality mineral or semi-synthetic oil suitable for petrol engines. Change every 15,000 km or 1 year to ensure proper lubrication of the timing components and valve train.
