Solution

1. Preparation

Ensure the engine is cool before starting work.
Disconnect the battery to prevent any electrical issues.
Gather necessary tools and parts.

Coolant:
- Check the coolant reservoir and radiator for leaks.
- If low, refill with the appropriate coolant type specified in the owner’s manual.
Transmission Fluid:
- Locate the transmission dipstick and pull it out.
- Wipe it clean, reinsert, and check the fluid level; if low, add appropriate transmission fluid.
- If burnt, drain the old fluid and replace it with fresh fluid, using a transmission fluid pump.

3. Replace Worn Components

Belts and Hoses:
- Inspect all belts for cracks or fraying and replace as necessary.
- Check hoses for leaks and replace any that are soft or damaged.
- Use a socket set to remove and replace any necessary components.

4. Electrical Inspection

Inspect wiring harnesses for burnt or exposed wires.
Repair or replace any damaged wiring with electrical tape or heat-shrink tubing as needed.
Ensure all connections are secure.

5. Reassembly and Testing

Reconnect the battery.
Start the engine to check for any leaks or smells.
Take the vehicle for a short drive to confirm the issue is resolved.
