Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Oil Level

Remove the dipstick, wipe it clean, reinsert it, and then remove it again to check the oil level.
If the oil is low, add the appropriate type of oil as specified in the owner’s manual.

3. Replace Oil Filter

Tools Required: Oil filter wrench, socket set, oil catch pan
Remove the old oil filter using the oil filter wrench.
Apply a small amount of oil to the rubber gasket of the new filter.
Install the new oil filter by hand until snug, then tighten it according to the manufacturer’s specifications.

4. Change Engine Oil

Tools Required: Socket set, oil catch pan, funnel
Remove the drain plug from the oil pan and allow the old oil to drain completely into the catch pan.
Replace the drain plug and tighten to the manufacturer's torque specification.
Pour in new oil through the oil fill cap using a funnel, ensuring it is the correct type and quantity as per the owner’s manual.

5. Replace Oil Pressure Sending Unit (if faulty)

Tools Required: Socket set, wrench
Locate the oil pressure sending unit (usually near the oil filter).
Disconnect the electrical connector and remove the sending unit using a socket.
Install the new sending unit and reconnect the electrical connector.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and check for oil pressure warning light.
Monitor the oil pressure gauge to ensure proper operation.
