Solution

1. Preparation

Tools Required: OBD-II scanner, mechanic's stethoscope, socket set, fluid containers, safety gloves, and goggles.
Ensure the vehicle is parked on a level surface with the engine turned off and cooled down.
Disconnect the battery to prevent electrical shorts while inspecting components.

2. Change Engine Oil and Filter

Sub-steps:
1. Place a fluid container under the oil pan and remove the oil drain plug using the socket set.
2. Allow the old oil to fully drain, then replace the drain plug and torque it to the manufacturer's specification.
3. Remove the old oil filter using an oil filter wrench and install a new filter, ensuring the rubber O-ring is lubricated.
4. Refill the engine with the correct type and amount of oil as specified in the owner’s manual.

3. Inspect and Replace Serpentine Belt (if necessary)

Sub-steps:
1. Locate the serpentine belt tensioner and use a wrench to relieve tension on the belt.
2. Remove the belt from pulleys and inspect for cracks or wear.
3. Install a new serpentine belt, ensuring it is routed correctly around all pulleys.
4. Reapply tension using the tensioner.

4. Address Loose Components

Sub-steps:
1. Tighten any loose bolts or brackets found during the visual inspection.
2. Secure any loose heat shields around the exhaust system.
3. Replace any damaged hoses or components that may contribute to noise.
