What Should Be Replaced in a Car for Winter?
2 Answers
In winter, cars need to replace coolant, engine oil, and tires, and also promptly check the braking system. Here are the relevant precautions for cars in winter: 1. Check the shutters: Install additional insulation devices for the engine. 2. Adjust the carburetor: Set the preheating valve to the "Winter" position. 3. Adjust the specific gravity of the battery electrolyte: And adjust the engine regulator. 4. Take measures for cold protection, antifreeze, and anti-skid: In places with conditions, antifreeze can be added to the cooling system. When adding antifreeze, note that if the antifreeze in the cooling system is insufficient, do not use water as a substitute to add, to avoid increasing the freezing point of the antifreeze; in addition, antifreeze is toxic, so never use your mouth to siphon it.
Recently, I helped my dad with winter maintenance on his SUV and found these essential replacements. The engine oil should be a 0W grade with good low-temperature fluidity, as older cars using high-viscosity oil may suffer cylinder scuffing during cold starts. The windshield washer fluid must be switched to an antifreeze type—I've seen cases where regular fluid froze and cracked the entire reservoir. Also, check the antifreeze's freezing point; it should be at least 15 degrees below the local minimum temperature for safety. Tire pressure should be slightly reduced by 5% to improve traction, and friends in the north should remember to switch to snow tires. Lastly, don’t forget to prepare an emergency kit with a snow shovel and jumper cables. Last year, my colleague’s battery suddenly died, nearly stranding him in the suburbs.
