From the factory this vehicle uses a BCI 78 · 600 CCA battery, OE oil filter 12731179. Note the factory fuel filter and spark plug are now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

Service quick specs OEM factory data
Capacities, torques and tune-up values from the factory service manual.
This engine holds 7 qt of 5W-30 API engine oil, 75W-90 · GL-5 in the differential. Torque lug nuts to 100 ft-lbs, the oil drain plug to 19.0 ft-lbs. The firing order is 1-5-3-6-2-4. 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.
Normal service, condensed from the factory interval matrix.
Under the factory schedule, replace the spark plugs every 100,000 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.
