Fitment & sizes
Replacement part sizes and factory part numbers — battery, bulbs, filters and belts.
From the factory this vehicle uses a BCI 78 · 600 CCA battery, OE oil filter 12731172. Note the factory fuel filter is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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 4.5 qt of 5W-30 API engine oil, 80W-90 · GL-5 in the differential, DOT 3 brake fluid. Torque lug nuts to 140 ft-lbs, the oil drain plug to 18.0 ft-lbs. 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 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.
