Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Check and Top Off Engine Oil

Tools Required: Oil funnel, clean rag
Remove the oil filler cap.
Check the oil level with the dipstick; if it's low, add the appropriate oil type (5W-20 for most models).
Replace the oil filler cap securely.

3. Replace Oil Filter

Tools Required: Oil filter wrench, oil drain pan
Place the oil drain pan under the oil filter.
Use the oil filter wrench to remove the old oil filter.
Apply a thin layer of new oil on the rubber gasket of the new filter.
Install the new oil filter, tightening it by hand until snug.

4. Replace Engine Oil

Tools Required: Socket set, oil drain pan, funnel
Remove the oil drain plug using a socket wrench and allow the old oil to drain completely into the oil drain pan.
Replace the drain plug and tighten it to the manufacturer’s specifications (typically around 30 lb-ft).
Pour in the new engine oil using a funnel, ensuring the correct amount is added (typically 4.5-5 quarts).
Start the engine and let it run for a few minutes, checking for leaks around the oil filter and drain plug.

5. Check Oil Pressure Sending Unit

Tools Required: Socket set, multimeter
Locate the oil pressure sending unit.
Disconnect the electrical connector and use a multimeter to test for voltage and resistance according to the service manual specifications.
If faulty, replace the oil pressure sending unit.
