What to Do When a Car Won't Start in Winter?
2 Answers
In low temperatures, a car may experience difficulty starting. Possible reasons for failure to start include: 1. Battery failure: In winter, lower temperatures reduce the battery's capacity, and after prolonged use, the starting voltage may drop. 2. Slower oil flow: Cold weather increases the viscosity of engine oil, slowing its flow and increasing engine resistance, making it harder to start the car. It is advisable to use winter-specific engine oil during this season. 3. Frozen exhaust pipe or excessive valve carbon deposits: Combustion in the engine produces water vapor, which can condense in certain parts. If it doesn't melt for a long time, starting the car becomes difficult. In such cases, running the car at high speeds can help expel the moisture from the exhaust pipe. 4. Engine malfunction: Severe engine wear can also make starting the car difficult. 5. Frozen and blocked exhaust pipe: Water vapor from engine combustion freezes at the exhaust pipe muffler, a common issue in vehicles used infrequently or for short distances.
Last winter, my car often wouldn't start. Later I learned that the main issue is the battery tends to discharge weakly in cold weather. First, check if the battery voltage is low - if the gauge shows less than 12V, it's dangerous. Then inspect the spark plugs, as cold and humid conditions can easily cause carbon buildup or rust. Also, use thinner engine oil in winter, preferably 0W-grade. Remember to warm up the engine for a few minutes before attempting to start, and avoid stomping on the accelerator as it can damage the starter motor. It's best to keep a portable jump starter or jumper cables to ask neighbors for help. If all else fails, tow it to a repair shop to test battery life and the charging system. For regular maintenance, remember to change oil on schedule and clean battery terminals.
