Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical issues.

2. Change Oil and Filter

Tools Required: Socket set, oil filter wrench, drain pan, funnel, new oil and oil filter.
Remove the drain plug using a socket set and allow old oil to drain completely into the pan.
Replace the oil filter with a new one using an oil filter wrench.
Reinstall the drain plug and torque to the manufacturer’s specifications (usually around 20-30 ft-lbs).
Add new oil through the funnel, ensuring to use the correct type and quantity specified in the owner’s manual.

3. Inspect and Replace Oil Pump (if necessary)

Tools Required: Socket set, torque wrench, oil pump (if replacement is needed).
Remove any components obstructing access to the oil pump (e.g., timing cover).
Disconnect the oil pump from the engine block.
Install the new oil pump, ensuring to follow torque specifications for the mounting bolts.
Reassemble any components that were removed.

4. Test Oil Pressure

Tools Required: Oil pressure gauge.
Connect the oil pressure gauge to the oil pressure sending unit.
Start the engine and monitor the oil pressure readings; it should be within the manufacturer's specified range.
If readings are low, further investigation into the oil pump or engine bearings may be required.
