The Fiat 552 68 036 is a 1,598 cc, inline — four, naturally aspirated petrol engine produced between 2011 and 2018. It features a dual overhead camshaft (DOHC), 16 — valve cylinder head, and multi — point fuel injection (MPFI), delivering 88 kW (120 PS) at 6,000 rpm and 152 Nm of torque at 4,000 rpm. Designed for light commercial vehicles, it emphasizes reliability, ease of maintenance, and fuel efficiency.
Fitted to the Fiat Doblò (223), Fiat Qubo (225), and Fiat Fiorino (225)…
All production years (2011–2018) meet Euro 5 emissions standards .
The Fiat 552 68 036 is a 1,598 cc inline-four petrol engine engineered for compact commercial vehicles (2011–2018). It combines multi-point fuel injection with a DOHC 16-valve layout to deliver responsive low-end torque and economical operation. Designed to meet Euro 5 emissions standards, it balances durability with urban efficiency.

The Fiat 552 68 036 was used across Fiat's 223/225 platforms with transverse mounting and no licensed applications. This engine received platform-specific adaptations-shorter intake manifolds in the Qubo and revised engine mounts in the Doblò-and from 2014 the updated tensioner design improved timing belt reliability, creating 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.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 552 68 036 is generally reliable when maintained properly, but pre-2014 models are at risk of timing belt failure due to tensioner wear. Post-2014 revisions improved durability. Regular servicing, timely belt changes, and use of correct oil and fuel help ensure longevity. Avoid extended intervals and monitor for early signs of tensioner noise.
Key issues include timing belt tensioner failure (especially pre-2014), idle instability from throttle body carbon buildup, coolant leaks from the thermostat housing, and ignition coil misfires. These are documented in Fiat service bulletins and field reports. Preventive maintenance significantly reduces failure rates.
This engine was used in the Fiat Doblò (223), Qubo (225), and Fiorino (225) from 2011 to 2018. It powered base 120 HP petrol variants in Europe and select emerging markets. No licensed applications outside Fiat Group vehicles are documented.
Limited tuning potential exists. ECU remaps offer minor gains (~5–10%), but the naturally aspirated design and modest internals restrict output. Cold air intakes and exhaust upgrades yield minimal benefits. For meaningful performance, engine swaps (e.g., 1.6 Turbo) are more common than tuning the 552 68 036.
In combined driving, expect 7.2–8.4 L/100km (39–34 mpg UK). City driving may see 9.0 L/100km (31 mpg), while highway runs can achieve 6.5 L/100km (43 mpg). Real-world economy depends on driving style and vehicle weight. The engine is optimized for urban efficiency.
Yes. The 552 68 036 is an interference engine. If the timing belt fails, pistons contact open valves, causing severe internal damage. Immediate replacement of worn belts and tensioners is essential to avoid costly engine repairs.
Fiat specifies SAE 5W-30 mineral or synthetic oil meeting API SN/CF standards. Change oil every 15,000 km or annually. Proper lubrication supports the timing belt tensioner and valve train. Avoid oils not meeting API SN/CF to prevent premature wear.
