What Causes the Clicking Sound When Starting a Car?

[JocelynMarie]

The reasons for a clicking sound when starting a car are: 1. Insufficient body rigidity, causing deformation during driving, leading to friction or vibration between doors and frames; 2. Belt slippage damaging the generator, water pump, or power steering pump bearings; 3. Worn transmission bearings or gears; 4. Deformed, bulging, severely worn tire treads, or insufficient tire pressure. The steps for starting a car are: 1. Inspect the vehicle's surroundings before entering to ensure no obstacles affect safety; 2. Fasten the seatbelt upon entering; 3. Press the brake with the left foot and the accelerator with the right foot; 4. Insert the key and turn it clockwise to power on, waiting for the vehicle's self-check; 5. Check the dashboard for any abnormal warning lights; 6. Ensure the gear is in P or N, press the brake, turn the key clockwise to start, release the handbrake, and shift to D; 7. Turn on the left signal, check the left mirror and road ahead for safety, then release the brake and gently press the accelerator to start.
