What Are Common Vehicle Malfunctions and Their Repairs?

[Blanco]

Here is an introduction to common vehicle malfunctions and their repairs: Dead Battery: A dead battery can result from two causes—either the battery has reached the end of its lifespan or has malfunctioned, or the headlights were left on, causing a power drain. You can start the vehicle using one of the following three methods: towing or pulling by another vehicle; borrowing power from another vehicle; or using a downhill slope to start the engine. To jump-start the battery using jumper cables, follow these steps: Prepare two relatively thick wires (usually red and black if purchased from the market). Connect one end of the red wire to the positive terminal of the charged battery and the other end to the positive terminal of the dead battery. Connect one end of the black wire to the negative terminal of the dead battery and the other end to a metal part of the charged vehicle. Start the charged vehicle first to help the dead vehicle start. Note: The donor vehicle should be running. Connect the positive terminal first, then the negative terminal. After starting, disconnect the negative terminal first, then the positive terminal. This prevents accidental contact between the positive terminal and the vehicle body, which could cause a short circuit. Low Oil Warning: If the oil warning light (red) turns on and it’s not due to a sensor malfunction, it usually means the engine is low on oil. Continuing to drive with insufficient oil can lead to severe damage, such as pistons breaking the cylinder block, causing sudden engine shutdown. This is not only dangerous but also results in high repair costs. If a fuel tank leak occurs due to accidental impact and no repair shop is nearby, you can chew gum and press it onto the leak. Once dried, the gum can temporarily seal the leak, serving as an emergency fix. Tire Blowout: A tire blowout is an unexpected and dangerous situation while driving at high speeds. If a blowout occurs, stay calm, avoid sudden steering movements, and firmly grip the steering wheel to maintain control while gradually slowing down. After safely stopping, set up a warning triangle behind the vehicle to prevent secondary accidents, then replace the tire with the spare.
