How to Warm Up an Automatic Transmission Car in Winter?

[JudahMarie]

Automatic transmission car warm-up methods in winter are: 1. Idle warm-up for approximately 30 seconds to 1 minute; 2. Wait until the engine speed drops to around 1200 RPM and the coolant temperature rises to about 50 degrees; 3. Maintain slow driving for basically 3 to 5 minutes, then normal driving can commence. If a car is parked for an extended period in winter, the engine oil may flow back into the oil pan. When starting the car, the oil cannot immediately circulate to the engine, requiring some time to flow back. A car's operation consists of two parts: one part involves piston work, while the other generates heat. The less heat generated, the better. Additionally, the phenomenon of thermal expansion and contraction exists in car components. Maintaining the car's coolant temperature at 90 degrees is the optimal temperature.
