What to Do When a Car Won't Start in Winter?

[DeSadie]

Here are the solutions for a car that won't start in winter: 1. Check the battery status. When the battery is low on charge, the engine cranks weakly during startup, producing only clicking sounds, which may gradually turn into hissing noises upon repeated attempts. Avoid continuous ignition attempts to prevent draining the battery completely. In winter, avoid leaving the car parked for extended periods. Generally, it's advisable to drive the car around once a week to ensure the battery gets adequately recharged. 2. Use the appropriate engine oil. In winter, as temperatures drop, the viscosity of engine oil increases, making it harder to flow and thus increasing engine resistance. If starting the car is difficult, check whether the correct oil grade is being used. Oil grades consist of two parts: classification and viscosity specification. 3. Replace spark plugs promptly. After several years of use, spark plugs can develop issues such as carbon buildup, electrical leakage, excessive gap, or erosion, leading to difficulty in ignition. Both cold starts and even warm starts may become challenging, often requiring multiple attempts. Inspect and replace spark plugs as needed.
