Here are the precautions for warming up the car in winter: 1. Warm up smoothly and accelerate gradually. 2. Drive at low RPM and avoid aggressive driving behaviors such as deep throttle, sudden acceleration, sudden braking, etc. Here are the methods for warming up the car in winter: 1. Start driving 30 seconds to one minute after starting the engine. 2. Maintain a low speed and avoid driving at high RPM; keep the engine speed around 2000 RPM. 3. Resume normal driving only after the engine temperature rises to the normal operating temperature. Here are the reasons for warming up the car in winter: 1. After the car has been parked overnight, the engine oil flows back to the oil pan at the bottom of the engine. Therefore, when starting the engine in the morning, the upper part of the engine is without oil and lacks lubrication. 2. It takes about 30 seconds after starting for the oil pump to circulate the oil to the parts that need lubrication the most, such as the pistons, connecting rods, and crankshaft.
Don't be careless about warming up your car in winter. After years of driving, I've found it crucial to let the engine idle for a minute or two after a cold start. This allows the oil to circulate and protect internal engine components. Wait until the RPM drops and stabilizes before gently setting off, avoiding hard acceleration or high speeds for the first few kilometers. Also, check if the antifreeze's freezing point is low enough and ensure the battery is sufficiently charged, as cold weather drains it easily. Properly defrost windows too - wait for the temperature to rise before blasting hot air. I remember once driving off quickly without warming up, and the engine shook violently, costing me a fortune in repairs later. Developing this habit also saves fuel and significantly extends vehicle lifespan, especially during icy northern winters, making for safer driving overall.
Winter car warming requires wisdom. I often remind myself that one to two minutes of idling is enough; any longer just wastes fuel. Choose low-viscosity winter-specific engine oil to avoid excessive friction from cold contraction. Car batteries tend to lose charge in low temperatures, so ensure terminals are clean and corrosion-free. Don't let windshield washer fluid freeze and obstruct visibility. Wait until all dashboard warning lights disappear after a cold start before driving, and take it easy for the first few minutes—avoid steep hills or sudden acceleration. Regularly replacing the air filter during maintenance is essential; listen for smooth engine sounds. These tips can prevent car troubles, saving money and peace of mind.
