- Install the new oil filter by hand until snug, then tighten slightly more with the wrench.
Add New Oil:
- Replace the drain plug and torque to manufacturer specifications (typically 20-25 ft-lbs).
- Pour the recommended type and amount of new engine oil (typically 0W-20 for Honda Accord) into the engine via the oil filler cap.
- Start the engine and let it run for a few minutes to circulate the oil, then check for leaks.

3. Tire Rotation

Lift the Vehicle:
- Use a jack to lift the vehicle and secure it with jack stands.
Rotate Tires:
