The Chevrolet 2H0 is a 1,399 cc, inline — four, naturally aspirated petrol engine produced between 2008 and 2015. It features multi — point fuel injection (MPFI), dual overhead camshafts (DOHC), and 16 valves, delivering 74 kW (100 PS) and 130 Nm of torque. Designed for compact city cars, it prioritizes fuel efficiency and low maintenance costs.
Fitted primarily to the Chevrolet Spark (M300) and Aveo (T250/T300), the 2H0 was engineered for urban commuting and light — duty u…
Production years 2008–2010 meet Euro 4 standards; 2011–2015 models comply with Euro 5 depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Chevrolet 2H0 is a 1,399 cc inline-four petrol engine engineered for compact city cars (2008–2015). It combines MPFI fuel delivery with DOHC valvetrain architecture to deliver responsive urban performance and low running costs. Designed to meet Euro 4 and later Euro 5 emissions standards, it balances everyday drivability with economy.

The Chevrolet 2H0 was used across Chevrolet's M300/T250 platforms with transverse mounting and shared architecture with Opel for European variants. This engine received platform-specific adaptations-shorter intake manifolds in the Spark and revised ECU calibrations in the Aveo-and from 2012 the facelifted Aveo LCI adopted updated chain components, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The 2H0's primary reliability risk is timing chain tensioner wear on early builds, with elevated incidence in short-trip urban use. Internal GM quality reports from 2013 indicated a significant share of pre-2012 engines required chain inspection before 100,000 km, while UK DVSA records show catalytic converter failures in city-driven vehicles. Cold-start cycles and frequent idling increase chain and guide stress, making oil quality and interval adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 2H0 is generally reliable for city driving, but early models (2008–2011) had timing chain tensioner concerns. Later revisions (post-2012) improved guide and tensioner durability. When maintained with regular oil changes using GM dexos1 5W-30, these engines can exceed 150,000 km without major issues.
Primary issues include timing chain tensioner wear, coolant leaks from the thermostat housing, intake manifold runner binding, and valve cover oil leaks. These are documented in GM service bulletins, with the timing system being the most critical area for preventive maintenance.
The 2H0 was used in the Chevrolet Spark (M300, 2008–2015) and Aveo (T250/T300, 2008–2012) as the 1.4L petrol variant. It was also shared with the Opel Corsa D (1.4 XER) in European markets, though with different fuel system calibration.
Limited tuning potential exists. ECU remaps can yield modest gains (~10–15%), but the naturally aspirated design and MPFI system restrict significant power increases. Cold air intakes and exhaust upgrades offer minor improvements. Over-tuning risks destabilizing factory calibration and triggering emissions faults.
In combined driving, the 2H0 achieves approximately 6.2 L/100 km (~45.7 mpg UK). City driving ranges from 7.0–7.5 L/100 km (~37–39 mpg UK), while highway efficiency reaches ~5.0 L/100 km (~56 mpg UK). Real-world figures depend on driving style and vehicle condition.
Yes. The 2H0 is an interference engine. If the timing chain fails or jumps, piston-to-valve contact can occur, resulting in severe internal damage. Immediate attention to chain noise or warning lights is essential to prevent costly repairs.
GM specifies dexos1 5W-30 synthetic oil for the 2H0 engine. Oil changes should occur every 15,000 km or 12 months. Using the correct oil ensures proper timing chain lubrication and reduces wear on the upper guide system.
