How Many Minutes Does It Take to Warm Up a Car?
1 Answers
It takes about 30 seconds to 1 minute to warm up a car. The method to warm up a car is as follows: 1. Start the vehicle and keep the air conditioning turned off; 2. Let the car idle for about 1 minute to warm up; 3. Drive slowly after the engine runs smoothly; 4. Once the engine coolant temperature gauge rises by 1 to 2 bars, you can drive normally and use the air conditioning. The reasons why a car needs to be warmed up include: 1. After being parked for a long time, the engine oil flows back into the oil pan; 2. Before the engine reaches its operating temperature, the fuel supply system cannot effectively vaporize gasoline completely due to the low temperature; 3. When parked, the gear oil flows to the lower part of the transmission, leaving the upper part without lubrication during a cold start.
