2003 Dodge Stratus — 2.4L

From the factory this vehicle uses a BCI 86 COUPE · 525 COUPE CCA battery, OE oil filter 05175567AB. Note the factory engine air filter, fuel filter, front wiper blades and thermostat are now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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 w/ filter of 5W-30 API engine oil, DOT 3 brake fluid. Torque lug nuts to 65-80 ft-lbs, the oil drain plug to 18.0-21.0 ft-lbs. The firing order is 1-2-3-4-5-6. 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 engine oil and filter every 6,000 mi; spark plugs every 60,000 mi; coolant every 30,000 mi. The big-interval services (every 30,000 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.
