The GM LCV is a 3,564 cc, 60‑degree V6 petrol engine produced between 2010 and 2017. It features dual overhead camshafts (DOHC), variable valve timing (VVT), and direct fuel injection. In standard form it delivered 224 kW (301 PS), with peak torque of 358 Nm, providing strong, responsive power for mid — size and full — size applications.

Production years 2010–2017 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/5680).
The GM LCV is a 3,564 cc 60-degree V6 petrol engine engineered for mid-size and full-size sedans (2010-2017). It combines DOHC with direct injection and variable valve timing to deliver strong, responsive power and improved fuel efficiency. Designed to meet Euro 5 standards, it represents GM's push towards more efficient, higher-output V6 engines.

The GM LCV was used across GM's Epsilon II and Alpha platforms with transverse mounting. This engine received platform-specific adaptations-unique engine mounts for the Cadillac ATS and specific ECU calibrations for the Chevrolet Impala-creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
The LCV's primary reliability consideration is intake valve carbon buildup, inherent to its direct injection design. While not a mechanical failure, it is a documented maintenance item that can affect drivability if neglected. GM service data indicates cleaning is a common high-mileage service procedure. Using Top Tier fuel and adhering to oil change intervals are critical preventative measures.
Analysis derived from GM technical bulletins (2010-2017) and UK DVSA failure statistics (2015-2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The LCV is a robust and powerful engine. Its main long-term consideration is managing intake valve carbon buildup, which is a characteristic of its direct injection design, not a flaw. With regular maintenance, including periodic intake cleaning and strict oil changes using Dexos1 Gen 2, these engines can reliably exceed 250,000 km.
The most frequent issues are carbon buildup on intake valves (causing misfires), potential failure of the high-pressure fuel pump, and wear of the timing chain tensioner. Oil consumption due to piston ring wear can also occur in high-mileage examples. These are well-documented in GM service information.
The LCV 3.6L V6 was used in the Chevrolet Malibu (2013-2017), Chevrolet Impala (2014-2016), and Cadillac ATS (2013-2017). It was the top-tier V6 option for these models, replacing the previous LLT engine and offering significantly more power and efficiency.
Yes, the LCV responds very well to tuning. Simple ECU flashes can unlock 15-25 kW of additional power by optimizing timing and fuel maps. More aggressive modifications like a performance intake and exhaust can yield further gains. The engine's internals are strong and can handle moderate power increases reliably.
Fuel economy is respectable for a 3.6L V6. In a 2015 Malibu, expect around 13.0 L/100km in the city and 8.5 L/100km on the highway, averaging approximately 10.5 L/100km (27 mpg UK) combined. Actual figures vary significantly with driving style, vehicle weight, and conditions.
Yes. The LCV is an interference engine. If the timing chain fails or jumps significantly, the pistons can collide with the open valves, causing catastrophic internal engine damage. The timing chain is generally durable, but maintaining proper oil level and quality is crucial.
GM mandates the use of Dexos1 Gen 2-approved 5W-30 full synthetic oil. This specific formulation is critical for protecting the engine's high-compression design and variable valve timing system. Change intervals should not exceed 10,000 km or 12 months, whichever comes first.
