Solution

1. Preparation

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

2. Check and Top Off Oil Level

Locate the oil dipstick and remove it.
Wipe it clean, reinsert it fully, and remove it again to check the oil level.
If low, add the appropriate type of oil as specified in the owner’s manual.
Recheck the oil level after adding oil.

3. Replace Oil Filter

Using an oil filter wrench, remove the old oil filter.
Before installing the new filter, apply a thin layer of fresh oil to the rubber gasket of the new filter.
Install the new oil filter by hand, ensuring it is snug but not overtightened.

4. Inspect and Replace Oil Pump (if necessary)

Drain the engine oil using a drain pan and remove the oil pan.
Inspect the oil pump for wear and blockage.
If defective, remove the oil pump by loosening the mounting bolts and replacing it with a new pump.
Reinstall the oil pan with a new gasket, ensuring all bolts are torqued to the manufacturer's specifications.

5. Test Oil Pressure

Install an oil pressure gauge in place of the oil pressure sending unit.
Start the engine and monitor the oil pressure reading; it should be within the manufacturer’s specified range.
If pressure is still low, further investigation is necessary.
