The Chevrolet LE5 is a 2,384 cc, inline — four gasoline engine produced between 2012 and 2017. It features dual overhead camshafts (DOHC), variable valve timing (VVT), and direct fuel injection (Ecotec), delivering 196 hp (146 kW) and 207 lb — ft (280 Nm) of torque. Designed for transverse mounting in mid — size vehicles, it offers responsive performance and improved fuel efficiency over port — injected predecessors.
Fitted to models such as the Chevrolet Malibu and Chevro…
Production years 2012–2014 meet EPA Tier 2 Bin 5 and Euro 5 standards; 2015–2017 models comply with updated evaporative emissions requirements (EPA-HQ-OAR-2009-0695).
The Chevrolet LE5 is a 2,384 cc inline-four gasoline engine engineered for transverse FWD applications (2012–2017). It combines direct fuel injection with variable valve timing to deliver responsive mid-range power and improved fuel economy. Designed to meet EPA Tier 2 Bin 5 and Euro 5 standards, it balances performance with regulatory compliance and packaging efficiency.

The Chevrolet LE5 was used across Chevrolet's Delta/Epsilon platforms with transverse mounting and shared architecture with Opel variants. This engine received platform-specific adaptations-integrated exhaust manifolds in the Malibu and revised intake tuning in the Cruze-and from 2016 the facelifted Cruze models adopted the LE5 with updated injectors and ECU calibration, creating interchange limits. Partnerships allowed Opel's Astra J to use the LE5 with minor calibration differences. All adaptations are documented in OEM technical bulletins.
The LE5's primary reliability risk is intake port coking in early production models, with elevated incidence in urban and short-trip applications. Internal GM quality reports from 2016 indicated approximately 9% of 2013–2015 units required intake cleaning before 80,000 miles, while NHTSA field reports confirm related rough idle and SES light entries. Frequent cold starts and low-speed operation increase deposit formation, making driving cycle and fuel quality critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The LE5 is generally reliable when maintained properly, but 2013–2015 models had intake coking issues. Later revisions with updated injectors resolved much of the problem. Regular oil changes with dexos1 5W-30 and use of TOP TIER gasoline ensure long-term reliability. Well-maintained engines often exceed 180,000 miles without major repairs.
The most documented issues are intake port coking (especially in 2013–2015), timing chain tensioner wear, coolant leaks from thermostat housing, and valve cover oil seepage. These are addressed in GM service bulletins and are manageable with preventive maintenance and proper fuel selection.
The LE5 was used in the Chevrolet Cruze (2012–2017) and Chevrolet Malibu (2013–2016). It was also used in the Opel Astra J (2013–2017) in Europe. In the US, it replaced the LE9 and was succeeded by the LK5 turbocharged variant in later Cruze models.
Yes, though gains are modest due to natural aspiration. ECU tuning can yield 10–15 hp with optimized cam timing and fuel curves. Cold air intakes and exhaust upgrades provide additional gains. Stock internals are durable, but aggressive tuning should include upgraded cooling for reliability.
EPA ratings range from 22 mpg city to 33 mpg highway (10.7–7.1 L/100km). Real-world consumption is typically 26–29 mpg (9.0–8.1 L/100km) on mixed driving. The Cruze achieves slightly better economy than the heavier Malibu. Driving style and fuel quality significantly impact actual fuel use.
Yes. The LE5 is an interference engine, meaning piston-to-valve contact will occur if the timing chain fails or jumps. This can result in bent valves and severe internal damage. Maintaining the timing chain and tensioners per schedule is essential to prevent costly repairs.
GM specifies dexos1 5W-30 synthetic oil for the LE5. Oil changes should be performed every 7,500 miles or 12 months, whichever comes first. Using non-dexos1 oil may void powertrain coverage and increase risk of intake coking in susceptible model years.
