2.2L ECOTEC Engine
The 2.2L ECOTEC engine is a twin-cam, 16-valve power plant that produces 145 horsepower and 155 lb.-ft. of torque. Standard on Cobalt Coupe and Sedan models, LS models and LT Sedan.
2.2L ECOTEC engine highlights:
Has undergone some of the toughest and most comprehensive tests ever conducted at GM Powertrain.
The cylinder head and engine block are made of lightweight aluminum.
Noted for its low noise and vibration levels, a result of the engine's rigid structure, counter-rotating balance shafts, structural oil pan and other features.
Designed to be driven for 5 years or 150,000 miles (whichever comes first) before replacing the coolant, for 100,000 miles before changing the spark plugs and, based on driving conditions, without ever changing the automatic transmission fluid (on Cobalt models equipped with this transmission).
Twin counter-rotating balance shafts housed in the cylinder block help cancel out the secondary vertical shaking forces inherent in a four-cylinder engine.
The line of ECOTEC engines in Cobalt use direct-mount accessories to eliminate noise and vibration.
Long-lasting chain-drive systems and hydraulic lash adjusters also deliver quiet and smooth dependability.
