Solution

1. Preparation

Gather tools and parts. Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required: OBD-II scanner, socket set, oil pressure gauge, oil filter wrench, torque wrench, oil catch pan, rags.
Safety Warnings: Allow the engine to cool before starting any work.

2. Check and Replace Oil

Sub-steps:
1. Remove the engine oil dipstick and wipe it clean.
2. Reinsert the dipstick and remove it again to check the oil level.
3. If the oil level is low, add the recommended oil type as specified in the owner’s manual.
4. Check the oil condition; if it appears dark or contaminated, proceed to change the oil.

3. Replace Oil Filter

Sub-steps:
1. Place an oil catch pan under the oil filter.
2. Use an oil filter wrench to remove the old oil filter.
3. Apply a small amount of new oil to the rubber gasket of the new filter.
4. Install the new oil filter, hand-tightening it securely.

4. Test Oil Pressure

Sub-steps:
1. Remove the oil pressure sending unit from the engine.
2. Install the mechanical oil pressure gauge in place of the sending unit.
3. Start the engine and observe the oil pressure reading. It should be within the specified range (consult the service manual for values).
4. If pressure is low, the oil pump may need to be replaced.

5. Replace Oil Pump (if necessary)

Sub-steps:
1. Drain the engine oil.
2. Remove any components obstructing access to the oil pump (e.g., oil pan).
3. Unbolt and remove the old oil pump.
4. Install the new oil pump, ensuring proper alignment and torque specifications.
5. Reassemble components and refill with new oil.
