Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working.

2. Change Engine Oil and Filter

Drain the engine oil:
- Locate the oil drain plug, place a drain pan underneath, and remove the plug with a socket wrench.
- Allow the oil to completely drain out.
Replace the oil filter:
- Use an oil filter wrench to remove the old filter.
- Lubricate the rubber gasket of the new filter with fresh oil and install it hand-tight.
Refill with new oil:
- Replace the drain plug and torque it to the manufacturer’s specification.
- Add the recommended oil type and amount through the oil filler cap.

3. Inspect and Replace Serpentine Belt

Remove the belt:
- Locate the serpentine belt tensioner and use a wrench to relieve tension.
- Slide the belt off the pulleys and remove it.
Install the new belt:
- Route the new belt according to the belt routing diagram (usually found on a sticker under the hood).
- Release the tensioner to put tension on the new belt.

4. Inspect and Tighten Engine Mounts

Visual inspection:
- Check for cracks or damage on the engine mounts.
Tighten bolts:
- Use a torque wrench to tighten the mounting bolts to the manufacturer’s specifications.
