Answer:
1. Perform regular based-on-time or based-on-use inspections and adjustments.
2. Perform regular good quality replacements according to use or/and environment conditions
Step-by-step explanation:
The best approach to keeping a car in a safe working order is to perform preventive maintenance activities to avoid unexpected failures that could put at risk people in a car. These preventive maintenance activities could be categorized into two groups:
- Regular based-on-time or based-on-use inspections and adjustments.
- Regular good quality replacements.
Those maintenance activities based-on-time (generally, based on days) or based-on-use (according to miles or kilometers) inspections and adjustments include those performed, at least, on main components fluids levels and working conditions of:
- Motor oil level and oil quality conditions.
- Motor coolant system level.
- Braking system liquid level.
- Steering system liquid level.
- Tires pneumatic pressure.
- Oil leakage presence below motor, gears box (manual transmission) or automatic transmission or in front or/and rear axles.
- Condition of shock absorbers (suspension system).
Those maintenance activities based on regular good quality replacements depend on the evaluation of the previous ones and include main components such as:
- Motor oil.
- Spark plugs.
- Oil/Air/Gas filters.
- Headlights and stop lights.
- Battery.
- Tires.
- Brake's pads and brake rotor rectification.
Good quality means replacements that meet quality norms and well-performed maintenance activities.
Again, these are activities that are performed in main and critical components, that is, a failure on them may have a high impact with high consequences (including loss of life) for those inside the car.
