- Reassemble the air filter cover and secure it properly.

3. Engine Oil Change

Gather Tools:
- Oil filter wrench, socket set, drain pan, funnel, and new oil and filter.
Change Oil:
- Start the engine to warm the oil, then turn it off.
- Place a drain pan under the oil pan and remove the drain plug.
