Solution

1. Preparation

Gather 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 shorts.

2. Check Oil Level and Condition

Remove the dipstick and clean it with a lint-free cloth.
Reinsert the dipstick fully and remove it again to check the oil level.
If oil is low, add the appropriate type of engine oil (5W-20 for most models) until it reaches the full mark.
Inspect the oil for contaminants or discoloration; if the oil is dirty, a change is recommended.

3. Inspect and Replace Oil Filter

Locate the oil filter and inspect it for damage or clogs.
If necessary, remove the old oil filter using an oil filter wrench.
Apply a thin layer of new engine oil to the rubber O-ring of the new oil filter.
Install the new oil filter, ensuring it is hand-tightened properly.

4. Check and Replace Oil Pump (if necessary)

Remove the oil pan by loosening the bolts securing it to the engine block (use a torque wrench to prevent damage).
Inspect the oil pump for wear or damage; replace if faulty.
Ensure the oil pump is properly aligned and bolted back into place.

5. Refill Engine Oil

After replacing the oil filter and checking the oil pump, refill the engine with the correct type and amount of oil.
Start the engine and let it idle for a few minutes, then turn it off and check the oil level again, adding oil as necessary.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and monitor the oil pressure gauge and warning light.
