Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the battery to avoid any electrical issues.

2. Check and Replace Engine Oil

Sub-steps:
1. Remove the oil filler cap and check the condition of the oil on the dipstick.
2. If oil level is low or oil appears dirty, drain the old oil using a wrench to remove the drain plug.
3. Replace the oil filter with a new one.
4. Refill the engine with the appropriate type and amount of oil as specified in the owner's manual.
5. Reinstall the drain plug and ensure it is properly torqued.

3. Inspect and Replace Oil Pump

Sub-steps:
1. Remove any components obstructing access to the oil pump (e.g., timing cover).
2. Disconnect the oil pump from the engine block.
3. Install the new oil pump, ensuring proper alignment and sealing.
4. Reassemble any removed components and torque to specifications.

4. Resolve Oil Pressure Issues

Sub-steps:
1. Install a mechanical oil pressure gauge to verify actual oil pressure.
2. If pressure is low, investigate and replace the oil pressure sending unit if faulty.
3. Clear any blockage in oil passages by flushing the system if necessary.
