What is the method for warming up a car?
2 Answers
Let the car warm up by idling for 1 to 2 minutes after starting the vehicle, allowing the engine coolant to reach normal operating temperature before driving. The purpose of warming up a car is: 1. After prolonged parking, the upper part of the engine lacks lubrication; warming up delivers oil to critical components like pistons, connecting rods, and crankshafts. 2. When the engine is cold, the fuel injection system cannot effectively vaporize gasoline due to low temperatures. 3. In cold conditions, gear oil settles at the bottom of the transmission and only circulates to lubricate the upper parts when the gears begin rotating during driving.
Warming up my car is quite simple: after starting the engine, don't rush to drive. Let it idle for 5 to 10 minutes. I often do this in cold weather to allow the oil to fully circulate and lubricate the engine internals, as a cold start can accelerate wear. In summer, the warm-up time can be shortened to just 3 minutes. After warming up, I drive slowly for a few minutes to let the transmission and brake systems warm up as well. A related tip is to choose the right oil viscosity—lower viscosity oil flows better in winter. Remember, warming up helps the car's heater warm the interior faster, so you won't be shivering. Also, check the coolant level to ensure efficient and safe warm-up. Developing this habit makes the car more durable, maintains stable fuel consumption, and avoids early repair troubles.
