Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts during repair.

2. Check and Refill Engine Oil

Sub-steps:
1. Remove the oil filler cap.
2. Pull out the dipstick, wipe it clean, reinsert, and then remove again to check the oil level.
3. If the oil level is low, add the recommended engine oil (5W-30 synthetic is typically recommended for this model).
4. Recheck the oil level and ensure it is at the proper mark on the dipstick.

3. Replace Oil Filter

Tools Required: Oil filter wrench, socket set.
Sub-steps:
1. Locate the oil filter and place a drain pan underneath to catch any oil.
2. Use the oil filter wrench to loosen and remove the old oil filter.
3. Apply a thin layer of new oil to the rubber gasket of the new filter.
4. Install the new oil filter by hand until snug, then tighten it according to manufacturer specifications (usually 3/4 to 1 full turn after the gasket contacts the surface).

4. Oil Pump Inspection

Sub-steps:
1. Remove the engine cover if applicable.
2. Inspect the oil pump for any visible damage or leaks.
3. Check the oil pump drive belt for wear and proper tension.
4. If necessary, remove the oil pump for further inspection and replace it with a new one if defective.

5. Reassemble and Test

Reconnect the battery.
Start the engine and let it idle while monitoring the oil pressure warning light.
Check for any leaks around the oil filter and oil pan.
