What Are the Basic Knowledge Points of Car Maintenance?

[PaisleeLee]

Automobiles are prone to issues such as failure to start, steering wheel vibration at high speeds, and heavy steering. Here are the detailed explanations for car maintenance: Failure to Start: First, check whether components like the high-voltage wires have become damp due to rain exposure. If so, dry the damp parts before attempting to start the engine. Next, inspect the spark plugs for damage. If they are damaged, simply replace them with new ones. Also, verify whether the battery voltage is sufficient. Sometimes, leaving the lights on for an extended period can drain the battery. In such cases, shift the car into second gear, press the clutch, and use another vehicle to tow-start it. Steering Wheel Vibration at High Speeds: When driving at high speeds or at a certain high speed, the car may exhibit instability, wobbling, or even steering wheel vibration. If alignment and suspension components are confirmed to be in good condition, the first step should be to perform tire dynamic balancing.
