What Are the Reasons for a Car Not Starting in Winter?
2 Answers
Car not starting in winter can be caused by: 1. Insufficient battery power; 2. Incorrect gear position; 3. Locked steering wheel; 4. Low engine temperature, increased lubricant viscosity, and poor fuel volatility; 5. Dirty throttle body; 6. Faulty water temperature sensor; 7. Faulty spark plugs. Solutions for a car not starting in winter include: 1. Turn the key to the ON position, press the clutch and shift into first gear, push the car until it reaches a certain speed, then release the clutch and press the accelerator; 2. Find another car, position the two cars facing each other, open the hood, connect the red end of the jumper cable to the positive terminal of the battery, and the other end to the other car.
In winter, the most common issue for a car not starting is a weak battery. Battery power depletes quickly in cold weather, especially if the car is parked outside overnight in low temperatures. I've personally encountered this several times, unable to start the car in the early morning, only to find out later that the battery was old and needed replacement. It's best to check the battery condition before winter each year. Oil viscosity is another issue; conventional oil thickens in low temperatures, making the engine hard to start. Switching to full synthetic low-temperature oil can help a lot. Dirty spark plugs or faulty igniters can also cause starting problems, which can be avoided by regular cleaning or replacement. A simple tip: try to park the car in a garage to keep it warm, or preheat the engine for a short while before starting it in the morning to prevent it from getting too cold.
