Specifications
The GM 2.4 Ecotec engine is a 4-cylinder gasoline engine available in different versions such as the LE5, LAF, LEA, and LE9. It produces around 164 to 182 horsepower and has a 2.4-liter (2,384 cc) displacement. The 2.4 ecotec engine has an aluminum block and cylinder head, DOHC, 4 valves per cylinder, and Variable Valve Timing (VVT). Some versions use port fuel injection, while others use direct injection. The compression ratio ranges from about 10.4:1 to 11.2:1, depending on the version. It holds about 4.7 liters (5 quarts) of engine oil with the filter, and SAE 5W-30 oil is commonly recommended.
Engine Variants
LE5
The LE5 is a 2.4L naturally aspirated Ecotec engine featuring dual variable valve timing (VVT) and port fuel injection. Depending on the application and model year, it produces up to 164–177 horsepower and was used in a variety of GM cars and SUVs.
LE9
The LE9 is a flex-fuel version of the LE5 designed to operate on both gasoline and E85 ethanol fuel. It retained the basic 2.4L naturally aspirated architecture while incorporating fuel-system and calibration changes to support ethanol blends.
LT (VVT Hybrid)
The LT, sometimes referred to as the VVT Hybrid, is a specialized LE5-based engine developed for early GM mild-hybrid applications. It combined the 2.4L VVT engine with GM’s hybrid system, including applications such as the Saturn Aura Green Line, to improve fuel efficiency.
LAF
The LAF marked the transition of the 2.4L Ecotec to direct fuel injection (DI). It featured a higher compression ratio and redesigned pistons, allowing improved combustion efficiency and stronger performance, with output around 180 horsepower depending on the application.
LEA
The LEA is a flex-fuel development of the LAF direct-injection engine. It retained the DI architecture while adding the ability to run on E85 ethanol fuel, making it suitable for a range of GM sedans, crossovers, and SUVs.
LUK
The LUK is closely related mechanically to the LEA direct-injection 2.4L engine but was specifically configured for use with GM’s assist mild-hybrid system. The combination of the gasoline engine and electric assist was designed to improve fuel economy and reduce emissions.
