Service quick specs OEM factory data
Capacities, torques and tune-up values from the factory service manual.
This engine holds 7 qt w/ filter of 5W-20 API engine oil, 80W-90 · GL-5 in the differential, DOT 3 · SAE J1703 brake fluid. The firing order is 1-8-4-3-6-5-7-2. 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 8,000 mi; spark plugs every 32,000 mi; coolant every 97,500 mi. The big-interval services (every 97,500 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.
