Solution

1. Preparation

Gather tools and necessary parts.
Disconnect the battery to ensure safety while inspecting electrical components.

2. Inspect and Replace Engine Oil

Check oil level on the dipstick; if low, top off with the recommended oil type.
If oil is burnt or contaminated, drain the oil and replace it with fresh oil.
- Tools Required: Socket set, oil filter wrench, oil catch pan.
- Sub-steps:
  1. Remove the drain plug and let the old oil drain completely.
  2. Replace the oil filter.
  3. Reinstall the drain plug and torque to manufacturer specifications.
  4. Fill with fresh oil as per specifications (usually 0W-20 or 5W-20).

3. Brake Inspection and Replacement

Inspect brake pads and discs for wear.
- Tools Required: Jack and jack stands, lug wrench, brake caliper tool.
- Sub-steps:
  1. Lift the vehicle and remove the wheel.
  2. Inspect brake pads for thickness; if less than 3mm, replace.
  3. Check the rotor for scoring or overheating; replace if necessary.
  4. Install new brake pads and reassemble the wheel.

4. Electrical System Inspection

Check for damaged wiring or melted insulation.
- Tools Required: Multimeter, wire strippers.
- Sub-steps:
  1. Visually inspect wiring harnesses around the engine and under the dashboard.
  2. Use a multimeter to test for continuity in suspect wiring.
  3. Repair or replace damaged wires as needed.

5. Coolant System Check

Inspect coolant levels and check for leaks in the radiator.
- Tools Required: Coolant pressure tester.
- Sub-steps:
  1. Check coolant reservoir for proper level; add coolant if low.
  2. Pressurize the cooling system and look for leaks around hoses and the radiator.
  3. Replace any damaged hoses or the radiator if leaks are found.
