Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and is turned off.
Disconnect the battery to ensure safety during the repair.

2. Change Engine Oil and Filter

Tools Required: Wrench set, oil filter wrench, oil catch pan.
Drain the old oil:
- Position the oil catch pan under the oil pan.
- Remove the oil drain plug using a wrench and let the oil drain completely.
Replace the oil filter:
- Use an oil filter wrench to remove the old oil filter.
- Lubricate the rubber gasket on the new oil filter with fresh oil, then install it by hand.
Refill with new engine oil:
- Replace the oil drain plug and tighten it to the manufacturer's specified torque (usually around 20-30 ft-lbs).
- Pour new oil through the oil filler cap (consult the owner’s manual for the correct type and amount of oil).

3. Inspect and Replace Oil Pressure Sending Unit (if necessary)

Tools Required: Wrench set, socket set.
Locate the oil pressure sending unit on the engine block.
Disconnect the electrical connector and remove the unit using the appropriate socket.
Install the new oil pressure sending unit by reversing the removal steps and ensure it is secured correctly.

4. Inspect and Replace Oil Pump (if necessary)

Tools Required: Socket set, torque wrench, engine hoist (if required).
Drain the oil and remove the oil pan as previously described.
Remove the old oil pump by disconnecting any bolts and hoses connected to it.
Install the new oil pump, ensuring it is aligned correctly and secured to the manufacturer’s torque specifications.
