Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, coolant tester, flashlight
Disconnect the battery to prevent any electrical shorts while inspecting the engine.

2. Inspect for Leaks

Visually check for oil, coolant, or other fluid leaks on the engine and under the vehicle.
Use a flashlight to illuminate hard-to-see areas.
Clean any visible leaks and check after running the engine to identify the source.

3. Address Fluid Issues

If oil is low or burnt, change the engine oil and replace the oil filter.
- Sub-steps:
  1. Drain the old engine oil using an oil pan.
  2. Replace the oil filter with a new one.
  3. Refill with the manufacturer-recommended oil type and capacity.
If coolant is low or contaminated, flush and refill the cooling system.
- Sub-steps:
  1. Drain the old coolant into a container.
  2. Flush the system with water until clean.
  3. Refill with the specified coolant mixture.

4. Replace Damaged Components

If any electrical wires, belts, or hoses show signs of damage or wear, replace them as necessary.
- Sub-steps:
  1. Remove the damaged component using appropriate tools.
  2. Install the new component and ensure all connections are secure.
  3. Check for proper routing of belts and hoses to prevent future contact with hot surfaces.

5. Reassemble and Test

Reconnect the battery.
Start the engine and monitor for any unusual smells, sounds, or warning lights.
Allow the engine to reach normal operating temperature and check for leaks.
