Engine Options:
3.0L V6 SIDI (LFW), 3.6L V6 LPG (LWR), 3.6L V6 SIDI (LFX), 6.0L Gen-IV V8 L77, 6.2L Supercharged V8 LSA, 6.2L V8 LS3.
Horsepower Torque:
Specific horsepower and torque figures vary significantly by engine. For example, the LSA variant produced approximately 415 kW (550 hp) and 740 Nm (546 lb-ft) of torque. The LS3 V8 produced around 317 kW (425 hp) and 570 Nm (420 lb-ft).
Fuel Delivery:
Sequential Multi-Point Fuel Injection (SIDI for V6), Gasoline Direct Injection (GDI for some V6 variants), Multi-Point Fuel Injection for V8 models. The LWR engine is specifically designed for Liquid Petroleum Gas (LPG).
V6 Codes:
LFW (3.0L SIDI V6), LWR (3.6L LPG V6), LFX (3.6L SIDI V6).
V8 Codes:
L77 (6.0L Gen-IV V8), LSA (6.2L Supercharged V8), LS3 (6.2L V8).
Valve Actuation:
DOHC (Dual Overhead Camshafts) with VVT (Variable Valve Timing) for all V6 and V8 engines covered.
Oil Change Interval:
Typically 12 months or 15,000 km (whichever comes first), but consult the manual for specific engine and oil type recommendations.
Major Service Interval:
Refer to the manual for specific intervals for spark plug replacement, coolant changes, brake fluid changes, and transmission fluid services. These can vary by engine and transmission type.
Engine Oil:
Viscosity grades like 5W-30 or 0W-40 are common, with specific API or ACEA certifications required. Consult the manual for exact specifications for each engine variant (e.g., dexos1).
Transmission Fluid:
Dexron VI is typically specified for the automatic transmissions. Manual transmissions will have specific gear oil requirements.
Coolant:
GM's proprietary long-life coolant (often orange or pink) meeting specific GM specifications is required.
Common Problems:
Potential issues can include minor electrical gremlins, wear on suspension components over time, particularly with higher mileage vehicles, and specific concerns related to certain engine variants (e.g., oil consumption on older V6s, though the SIDI engines were generally improved). Fuel pump and ignition coil issues can also occur.
Oil Filter Part Number:
Part numbers vary by engine. Example for V6 engines might be AC-Delco CF341 or equivalent. Consult manual for exact fitment.
Air Filter Part Number:
Part numbers vary by engine. Example for V6 engines might be AC-Delco A2603C or equivalent. Consult manual for exact fitment.
