Solution

1. Preparation

Ensure the engine is cool before starting work to prevent burns.
Disconnect the battery to eliminate electrical hazards.
Gather all necessary tools and parts.

2. Inspect and Change Engine Oil

Tools Required: Socket wrench, oil filter wrench, oil catch pan, funnel.

3. Inspect and Replace Coolant

Sub-steps:
- Open the radiator cap (only when the engine is cool).
- Check coolant level in the reservoir; if low, inspect for leaks.
- If the coolant is contaminated or insufficient, drain and replace with a 50/50 mix of Honda-approved coolant.
- Bleed the cooling system to eliminate air pockets after refilling.
Tools Required: Radiator cap opening tool, coolant funnel, drain pan.

4. Inspect Electrical Components

Sub-steps:
- Visually inspect wiring harnesses for signs of wear or melting.
- Replace any damaged wires or connectors.
- Check all fuses related to the engine management and electrical systems.
Tools Required: Multimeter, wire strippers/crimpers.

5. Brake Inspection
