Service quick specs OEM factory data
Capacities, torques and tune-up values from the factory service manual.
This engine holds 10.0 qt of 15W-40 / 5W-40 / 10W-30 API engine oil, Rear: 8.6 in the differential, DOT 3 brake fluid. The firing order is 1-8-7-2-6-5-4-3. 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.
