How to Fix a Clicking Sound When Starting a Car
Replacing the Starter Motor
If you’re hearing a clicking sound when attempting to start your car, one possible cause could be a faulty starter motor. The starter motor is responsible for initiating the engine’s combustion process. Over time, the starter motor can wear out or become damaged, leading to a clicking sound instead of the usual engine ignition.
To replace the starter motor, you’ll need to locate it first. It’s typically situated near the engine and is connected to the battery and ignition system. Once you’ve identified the starter motor, disconnect the battery to ensure safety. Then, remove the mounting bolts that hold the starter motor in place. Carefully disconnect the electrical connections, such as the solenoid and wiring harness, before fully removing the old starter motor.
After removing the old starter motor, install the new one by following the reverse steps. Connect the electrical connections and secure the mounting bolts. Finally, reconnect the battery and test the car. If the clicking sound no longer persists, you’ve successfully replaced the starter motor.
Jump-Starting the Battery
Another possible cause of the clicking sound when starting your car is a weak or dead battery. If your battery doesn’t have enough power to initiate the engine ignition, it may produce a clicking sound instead.
To jump-start the battery, you’ll need a set of jumper cables and a functioning vehicle. Park the working vehicle close to the one with the dead battery, making sure the engines are turned off. Connect one end of the positive cable (usually red) to the positive terminal of the dead battery. Attach the other end of the positive cable to the positive terminal of the working battery.
Next, connect one end of the negative cable (usually black) to the negative terminal of the working battery. Instead of attaching the other end of the negative cable directly to the negative terminal of the dead battery, find an unpainted metal surface within the engine compartment of the vehicle with the dead battery. This will help prevent sparks and potential battery damage.
With the cables properly connected, start the engine of the working vehicle and let it run for a few minutes. Then, try starting the car with the dead battery. If it starts without any clicking sound, let both vehicles run for a while to allow the dead battery to recharge. Once the car with the dead battery is running smoothly, disconnect the jumper cables in the reverse order of connection.
Cleaning or Replacing Battery Connections
A loose or corroded battery connection can also cause a clicking sound when starting your car. Over time, the battery connections can become dirty or loose, hindering the flow of electrical current.
To clean the battery connections, start by disconnecting the negative cable (usually black) from the battery’s negative terminal. Then, remove the positive cable (usually red) from the positive terminal. Inspect the terminals and cables for any signs of corrosion, which may appear as white or greenish deposits.
If there is corrosion, mix a solution of baking soda and water and apply it to the affected areas. Use a wire brush to gently scrub away the corrosion. Rinse the terminals and cables with clean water and dry them thoroughly. Once clean, reconnect the positive cable to the positive terminal, followed by the negative cable to the negative terminal.
If the battery connections are severely corroded or damaged, it may be necessary to replace them. You can purchase new battery cables from an auto parts store and follow the same steps to disconnect and reconnect them.
