Solution

1. Preparation

Tools Required: Safety gloves, safety goggles, jack and jack stands, OBD-II scanner, basic hand tools (sockets, wrenches).
Safety Warnings: Ensure the engine is cool before starting any inspections. Disconnect the battery if working on electrical components.

2. Addressing Fluid Leaks

Sub-steps:
1. Locate the source of any identified leaks and clean the area to better identify the leak source.
2. Replace any faulty gaskets or seals if oil or coolant leaks are found.
3. Refill any low fluid levels with the manufacturer-recommended fluids.

3. Replacing Worn Belts and Hoses

Sub-steps:
1. Remove the engine cover if necessary to access belts and hoses.
2. Inspect belts for fraying or burning; replace if damaged.
3. Check hoses for cracks or softness; replace any that are compromised.
4. Ensure proper tension on belts and secure all clamps on hoses.

4. Addressing Overheating Issues

Sub-steps:
1. Check the coolant level in the reservoir and radiator; top off with a 50/50 mix of coolant and water if low.
2. Inspect the radiator for blockages or leaks; clean or replace as needed.
3. Ensure the thermostat is functioning correctly; replace if faulty.

5. Inspecting Electrical Components

Sub-steps:
1. Look for any signs of burnt wiring or connectors in the engine bay.
2. Repair or replace any damaged wiring; use heat-shrink connectors for a secure fix.
3. Reconnect the battery and check for proper operation of affected systems.
