Solution

1. Preparation

Tools Required: Socket set, screwdrivers, OBD-II scanner, multimeter, jack and jack stands, tire pressure gauge.
Ensure the vehicle is parked on a flat surface and the engine is cool before starting.

2. Inspect and Replace Belts

Sub-steps:
1. Open the hood and locate the serpentine belt.
2. Check for cracks, fraying, or signs of slipping.
3. If damaged, remove the tensioner bolt and release tension on the belt.
4. Replace the belt with a new one, ensuring proper routing as per the diagram typically located near the engine bay.
5. Reinstall the tensioner and tighten to manufacturer's specifications (usually around 15-25 ft-lbs).

3. Examine and Replace Tires

Sub-steps:
1. Use a jack to lift the vehicle and securely place it on jack stands.
2. Inspect each tire for wear, bulging, or overheating signs.
3. Measure tire pressure and inflate to the recommended PSI if low.
4. If tires are damaged, replace them with new ones, ensuring proper size and type as specified for the RAV4.
5. Recheck alignment after tire replacement if necessary.

4. Address Fluid Leaks

Sub-steps:
1. Identify any fluid leaks by checking underneath the vehicle and in the engine bay.
2. Clean any leaking areas and replace seals or hoses as required.
3. Ensure that all fluids (oil, coolant, brake fluid) are at proper levels and top up if necessary.
4. Dispose of any fluids responsibly if they need to be replaced.
