Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Change Engine Oil and Oil Filter

Sub-steps:
1. Remove the drain plug using a socket set and allow the old oil to drain completely into a pan.
2. Replace the drain plug and tighten it to the manufacturer's specified torque (typically around 25-30 ft-lbs).
3. Remove the old oil filter using an oil filter wrench, ensuring to lubricate the rubber gasket on the new filter with fresh oil before installation.
4. Install the new oil filter, tightening it according to manufacturer's specifications (usually hand-tight plus a quarter turn).
5. Refill the engine with the correct type and amount of new oil (typically 5W-30 or 0W-20, depending on the model) using a funnel.

3. Inspect and Replace Oil Sending Unit (if necessary)

Sub-steps:
1. Locate the oil sending unit, typically found near the oil filter or on the engine block.
2. Disconnect the electrical connector from the oil sending unit.
3. Remove the oil sending unit using a socket or wrench.
4. Install the new oil sending unit, tightening it to the specified torque (usually around 20-25 ft-lbs).
5. Reconnect the electrical connector.
