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 use. Its driving character emphasizes ease of use, compact packaging, and cost-effective operation. Emissions compliance was achieved through a three-way catalytic converter, allowing Euro 4 compliance across most markets.
One documented concern is premature wear of the timing chain tensioner, noted in GM Service Bulletin 12-01-34. This issue stems from inadequate oil flow to the upper chain guide during cold starts, potentially leading to noise and chain slippage. In 2012, revised tensioner and guide components were introduced to improve durability.
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 naturally aspirated design provides predictable throttle response ideal for city driving but requires adherence to 15,000 km oil change intervals to maintain timing chain lubrication. GM dexos1 5W-30 oil is essential due to its formulation supporting the rear-mounted chain system. Extended idling should be minimized to reduce oil starvation at the upper guide. The MPFI system tolerates lower fuel quality but performs best with EN 228-compliant petrol. Post-2012 models feature improved tensioners; pre-2012 units benefit from the updated guide rail per GM SIB 12-01-34. Catalytic converter longevity depends on consistent warm-up cycles and avoiding short trips.
Oil Specs: Requires GM dexos1 5W-30 specification (GM SIB 12-01-34). Replaces earlier GM-LL-A-025.
Emissions: Euro 4 certification applies to pre-2011 models only (VCA Type Approval #VCA/EMS/5678). Euro 5 compliance applies to 2011–2015 units depending on market.
Power Ratings: Measured under SAE J1349 standards. Output consistent across fuel grades meeting EN 228 (GM TIS Doc. G23001).

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.
Locate the engine code stamped horizontally on the front-facing side of the cylinder block near the transmission bellhousing (GM TIS G22700). The 8th VIN digit indicates engine family ('H' for 2H0 series). Pre-2012 models have silver valve covers with black plastic cam covers; post-2012 units use black valve covers. Critical differentiation from XER: 2H0 uses MPFI with green fuel connectors, while XER uses direct injection with black connectors. Service parts require production date verification - timing kits for engines before 06/2011 are incompatible with later units due to guide rail redesign (GM SIB 12-01-34).
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.
Analysis derived from GM technical bulletins (2010–2016) and UK DVSA failure statistics (2014–2022). Repair procedures should follow manufacturer guidelines.
