2003 Saturn L200, LW200

From the factory this vehicle uses a BCI 78 · 600 CCA battery, OE oil filter 12580255. Note the factory fuel filter, front wiper blades, serpentine belt and cabin air filter are now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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.

This engine holds 5 qt of 5W-30 API engine oil, DOT 3 brake fluid. Torque lug nuts to 92 ft-lbs, the oil drain plug to 18.0 ft-lbs. The firing order is 1-3-4-2. 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.

Under the factory schedule, replace the spark plugs every 100,000 mi; coolant every 100,000 mi. The big-interval services (every 100,000 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.
