Basic DIY Safety Rules for Car Checks

Many basic checks are safe when done carefully, but vehicles are heavy, hot, electrical, chemical, and sometimes unpredictable.

Basic DIY Safety Rules for Car Checks visual

Before You Start

  • Work on level ground with good light and ventilation.
  • Keep loose clothing, hair, and jewelry away from belts, fans, and pulleys.
  • Use eye protection and gloves when handling fluids or batteries.
  • Read the owner's manual before opening caps or disconnecting parts.

Never Compromise

  • Never get under a vehicle supported only by a jack.
  • Never open a hot radiator cap.
  • Never touch brake or exhaust parts right after driving.
  • Never install a larger fuse to replace a blowing fuse.

Know When To Stop

  • Stop if the task needs lifting, fuel system opening, airbag wiring, brake hydraulics, high-voltage hybrid parts, or programming tools.
  • Stop if you are unsure whether the car is stable, cool, or electrically safe.
  • A safe handoff to a mechanic is better than turning a small issue into an injury.
