Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery before beginning work.

2. Check and Top Off Oil

Remove the oil dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If low, add the appropriate type of oil specified in the owner’s manual.

3. Replace Oil Filter

Locate the oil filter and use an oil filter wrench to remove it.
Apply a thin layer of new oil to the rubber gasket of the new filter.
Install the new oil filter and tighten it according to the manufacturer’s specifications (usually hand-tight).

4. Change Engine Oil

Place an oil drain pan under the oil pan and remove the drain plug using a socket wrench.
Allow the old oil to completely drain into the pan.
Replace the drain plug and tighten it to the specified torque (typically around 25 ft-lbs).
Add new oil through the oil fill cap, using the type and amount specified in the owner’s manual.

5. Inspect and Replace Oil Pressure Sending Unit (if necessary)

Locate the oil pressure sending unit, typically found near the oil filter.
Disconnect the electrical connector and remove the unit using a socket wrench.
Install the new oil pressure sending unit and reconnect the electrical connector.
