The 2.0L engine in the 2011-2017 Buick Regal is a turbocharged inline-4 cylinder engine, producing 220 horsepower at 5,300 RPM and 258 lb-ft of torque at 2,000 RPM. It features direct fuel injection, dual overhead camshafts, and a forged steel crankshaft. The engine is compatible with regular unleaded fuel and has a fuel capacity of approximately 18 gallons. It is paired with either a 6-speed manual or 6-speed automatic transmission and is available in both front-wheel drive and all-wheel drive configurations.

Regular maintenance for the 2.0L engine includes oil changes every 5,000 to 7,500 miles using 5W-30 synthetic oil, tire rotations every 7,500 miles, and spark plug replacements every 60,000 miles. The engine air filter should be replaced every 15,000 miles, and the fuel filter every 30,000 miles. It is also recommended to inspect the turbocharger and intercooler hoses every 30,000 miles and replace them as needed. Always follow the maintenance schedule outlined in the owner's manual.

To install or replace parts on the 2.0L engine, ensure you have the proper tools and follow the step-by-step instructions in the service manual. Disconnect the negative battery terminal before starting any work. For turbocharger replacements, remove the intercooler and intake manifold, then carefully disconnect the turbocharger hoses and mounting bolts. For other components like the water pump or timing belt, follow the specific removal and installation procedures outlined in the manual. Always torque bolts to the specified values to avoid engine damage.

Common issues with the 2.0L engine include turbocharger failure, coolant leaks, and clogged fuel injectors. Start by checking the dashboard for error codes using an OBD-II scanner. If the turbocharger is faulty, you may notice a loss of power or a whining noise. Inspect the coolant system for leaks, especially around the hoses and water pump. For clogged fuel injectors, use a fuel injector cleaner or have them professionally serviced. Always refer to the service manual for detailed diagnostic procedures.

To optimize the performance of the 2.0L engine, ensure regular maintenance is performed, including the use of high-quality synthetic oil and proper fuel. Consider upgrading the air intake system to a high-flow unit and installing a performance exhaust system to improve airflow. Tuning the engine with a performance software calibration can also increase horsepower and torque. Additionally, monitor engine temperatures and boost pressure to ensure optimal operation. Avoid aggressive driving and maintain proper tire pressure for maximum efficiency.
