Solution

1. Preparation

Gather tools and parts required for inspection and repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to ensure safety.

2. Fluid Check and Replacement

Check engine oil level and condition:
- If oil is low or burned, drain the old oil and replace it with the manufacturer-recommended oil.
- Use an oil filter wrench to replace the oil filter.
- Refill with new oil and check for leaks.
Inspect coolant levels:
- If coolant is low, check for leaks in hoses and the radiator.
- If the coolant appears contaminated or burned, flush the cooling system and refill with new coolant.

3. Component Inspection

Inspect belts:
- Check for fraying or signs of melting; replace any damaged belts.
- Ensure proper tension and alignment.
Inspect hoses:
- Look for cracks or signs of wear; replace any damaged hoses.
- Ensure clamps are tight and not leaking.

4. Electrical Inspection

Check electrical connections for burnt or damaged wiring.
- Repair or replace any damaged wiring or connectors.
- Ensure all grounds are secure and clean.
