Service quick specs OEM factory data
Capacities, torques and tune-up values from the factory service manual.
This engine holds 5.0 qt of 5W-20 / 0W-20 engine oil, GM DEXRON gear lubricant in the differential, DOT 3 brake fluid. Torque the oil drain plug to 18.0 ft-lbs. The firing order is 1-2-3-4-5-6. Note the cylinder-head bolts finish on a torque angle (torque-to-yield) — they stretch permanently and should be replaced, not reused, during any head service.

Factory maintenance schedule OEM · verified
Normal service, condensed from the factory interval matrix.
Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs every 97,500 mi; coolant at 150,000 mi. The big-interval services (at 150,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Common OBD-II trouble codes
The most common OBD-II codes for this vehicle's emissions system. These are standardized SAE J2012 definitions, not vehicle-specific fault reports.
5.0 qt of 5W-20 meeting GM Dexos 1 specification or equivalent. Where temperatures fall below -20 degreesF, GM recommends using an SAE 0W-20 oil., per the factory manual.
