When the temperature is low in winter, car owners should warm up their cars before starting them. Due to different models, it can be roughly summarized as follows: after getting in the car, first turn the start key until the circuit is fully open (ACC is in the ON state). If it is a keyless start model, press the start button without pressing the brake, and wait until the circuit self-test is completed ( Generally, it is started after the airbag indicator light on the instrument panel is turned off). At this time, after passing the self-test of the entire vehicle circuit, the vehicle can help start in the best condition.
After the self-inspection is completed, turn on the ignition and warm up the car until the speed drops back to 1000 rpm. At this time, you can let the vehicle idle forward, and when the water temperature begins to rise, you can slowly refuel until the water temperature reaches about 90°C.
There is a warm-up process after the vehicle is started. The phenomenon that the water temperature rises very slowly means that the engine is warming up. The length of this time is determined by the water temperature sensed by the water temperature sensor. If the water temperature If there is no problem with the sensor, it may be that the thermostat is always performing a large cycle, causing the water temperature to rise slowly. It is recommended that the car owner mainly check the following two aspects (when the car is running, the temperature difference between the radiator inlet pipe and the outlet pipe can be used to determine whether it is the problem). Thermostat problem). Or go to the 4S store to check. However, the longer the car is heated, the better. If you have to wait until the water temperature rises completely, it will not only take a long time (generally more than 5 minutes at a temperature of 2°C to 5°C), but it will also form a large amount of carbon deposits, which will affect the performance of the engine.
