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.
