Solution

1. Preparation

Tools Required: Basic hand tools (sockets, wrenches), OBD-II scanner, brake cleaner, work gloves.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical issues during inspection.

2. Inspect and Repair Fluid Leaks

Sub-steps:
1. Look for leaks under the engine and transmission areas.
2. Clean any spilled fluids with brake cleaner and recheck for leaks after a short drive.
3. If leaks are found, replace the damaged seals, gaskets, or hoses as necessary.

3. Check and Replace Engine Oil

Sub-steps:
1. Remove the engine oil dipstick and check the oil level and condition.
2. If oil is low or burnt, drain the old oil using a socket to remove the drain plug.
3. Replace the oil filter and refill with the correct type and amount of oil (5W-20 or as specified).
4. Start the engine and let it run for a few moments, then recheck the oil level.

4. Inspect and Fix Cooling System

Sub-steps:
1. Check the coolant reservoir and radiator for proper fluid level and signs of leaks.
2. Inspect hoses for cracks or wear, replacing any damaged hoses.
3. If the coolant is low, refill with the appropriate type (Toyota Long Life Coolant).
4. Check the thermostat operation and replace if necessary.

5. Brake Component Inspection

Sub-steps:
1. Remove the wheel to access the brake components.
2. Inspect brake pads for wear and overheating signs (discoloration, burning smell).
3. Replace worn brake pads and check rotors for damage.
4. Ensure the caliper is functioning properly and not sticking.

6. Check Drive Belts

Sub-steps:
1. Visually inspect the drive belts for signs of fraying or cracks.
2. Adjust tension if applicable, or replace belts that show damage.
3. Ensure proper alignment and operation of all belts.
