Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Adjust Oil Level

Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level.
If the oil level is low, add the appropriate type of oil until it reaches the full mark.

3. Check Oil Filter Installation

Locate the oil filter.
Inspect visually for any signs of improper installation or leaks.
If the filter is loose, tighten it by hand or with an oil filter wrench (do not overtighten).

4. Replace Oil Filter (if needed)

If the oil filter is damaged or not installed correctly,
1. Use the oil filter wrench to remove the filter.
2. Lubricate the rubber gasket of the new filter with a little fresh oil.
3. Install the new filter by hand until snug.

5. Test Oil Pressure

Reconnect the battery terminal.
Install an oil pressure gauge to the oil pressure sending unit location.
Start the engine and observe the reading on the gauge. It should be within the manufacturer’s specified range (typically between 20-60 PSI).

6. Address Any Leaks

If leaks are found during inspection, address them by replacing gaskets or seals as necessary.
Clean any spilled oil from the engine bay to prevent false readings and ensure proper function.
