Place a drain pan under the oil pan and remove the drain plug to drain the old oil.
Replace the oil filter using the oil filter wrench.
Install the drain plug, then fill the engine with new oil according to the manufacturer’s specifications.

4. Inspect Exhaust System

Tools Required: Wrench set, flashlight
Visually inspect the exhaust system for loose bolts or rusted components.
Tighten any loose bolts and replace any damaged sections of the exhaust if necessary.

5. Check Drive Belt and Pulleys

Tools Required: Belt tensioner tool, socket set
