GMC Terrain 2010-2017 3.0L Engine Specifications

The 3.0L V6 engine is compatible with select 2010-2017 GMC Terrain models, primarily those with the SLT-2 trim. It features a 264-horsepower output, 222 lb-ft of torque, and a 6-speed automatic transmission. However, it is not compatible with models equipped with the 2.4L I4 or 3.6L V6 engines. Always verify your vehicle’s VIN and trim level before purchasing or installing this engine.

Regular maintenance for the 3.0L engine includes oil changes every 5,000-7,500 miles using 5W-30 synthetic oil, air filter replacement every 15,000-30,000 miles, and spark plug replacement every 100,000 miles. Additionally, inspect the timing belt, coolant, and transmission fluid periodically. Adhering to the manufacturer’s maintenance schedule ensures optimal performance and longevity of the engine.

Replacing the 3.0L engine involves disconnecting the battery, draining fluids, and removing components like the air intake, exhaust manifold, and transmission. Use an engine hoist to lift the old engine out and lower the new one in place. Reconnect all components, refill fluids, and test the engine. It’s recommended to consult the service manual or hire a professional for this complex procedure.

If the engine overheats, first check the coolant level and refill if low. Inspect for leaks, a faulty thermostat, or a malfunctioning water pump. Ensure the radiator fan is operational and the radiator is not clogged. If the issue persists, stop driving immediately and seek professional assistance to avoid engine damage.

To optimize performance, use high-quality synthetic oil, maintain proper tire pressure, and ensure the air filter is clean. Regularly check and replace spark plugs, and use premium fuel to enhance combustion efficiency. Consider upgrading the exhaust system for better airflow and performance tuning for improved horsepower and torque.
