1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery negative terminal.

2. Inspect and Tighten Loose Components

Tools Required: Socket set, torque wrench
Remove any covers obstructing access to engine components (if necessary).
Inspect all bolts and fasteners on the engine, particularly around the valve cover, intake manifold, and exhaust system.
Tighten any loose bolts to the manufacturer's specified torque values.

3. Check and Replace Engine Oil

Tools Required: Oil filter wrench, oil catch pan, funnel
Remove the oil drain plug and drain the old oil into an oil catch pan.
Replace the oil filter using an oil filter wrench.
Reinstall the drain plug and refill the engine with the recommended oil type and quantity.

4. Inspect Timing Chain/Belt Components

Tools Required: Socket set, torque wrench, timing cover removal tools
Remove the timing cover to access the timing chain/belt and tensioners.
Inspect the timing chain/belt for wear, slack, or damage.
Replace timing chain/belt and tensioner if necessary, ensuring all components are torqued to specification.
