Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and parked on a level surface.
Disconnect the negative terminal of the battery for safety.

2. Remove the Old Oil Filter

Tools Required: Oil filter wrench, oil catch pan, rags.
Place the oil catch pan under the oil filter to catch any residual oil.
Use the oil filter wrench to turn the filter counterclockwise and remove it.
Allow any remaining oil in the filter to drain into the catch pan.

3. Inspect and Clean

Inspect the gasket surface on the engine for any debris or old gasket material.
Clean the area thoroughly with a rag to ensure a proper seal for the new filter.

4. Install the New Oil Filter

Apply a small amount of new oil to the gasket of the new oil filter to ensure a good seal.
Hand-tighten the new oil filter in a clockwise direction until snug; do not overtighten.

5. Refill Engine Oil

If a significant amount of oil has leaked out, refill the engine oil using the appropriate type specified in the owner's manual.
Use a funnel to avoid spills and check the oil level with the dipstick.

6. Final Checks

Reconnect the negative terminal of the battery.
Start the engine and let it idle for a few minutes while checking for any leaks around the new oil filter.
Turn off the engine and recheck the oil level, topping off if necessary.
