What Are the Winter Maintenance Items for Cars?

[EthanFitz]

Winter car maintenance items include servicing the cooling system, replacing various fluids, maintaining preheating devices, and servicing electrical equipment. Below are detailed introductions: 1. Adding antifreeze. When temperatures are extremely low and conditions permit, antifreeze can be used. Before use, thoroughly clean the cooling system and choose high-quality, low-corrosivity antifreeze to prevent damage to engine components due to poor-quality antifreeze. 2. Changing engine oil. Use engine oil with lower viscosity. In low-temperature conditions, the viscosity of engine oil increases as the temperature drops, reducing fluidity. Therefore, timely replacement with lower-viscosity oil can compensate for or eliminate this adverse effect. 3. For engines equipped with preheating devices (mostly diesel), inspect and maintain the preheating equipment before winter to ensure good technical condition. Focus on checking the electrical circuits and fuel lines during maintenance to prevent poor preheating performance from affecting engine startup. 4. Checking and adjusting electrolyte density. Appropriately increase the electrolyte density to prevent the battery case from cracking due to excessively low electrolyte density.
