Three, idling speed, slow heating
When the car is started by the roasting car and steam preheating method, and the engine temperature rises to 40-50 degrees Celsius by low-speed operation, turn off the flame and add water (except for vehicles with antifreeze), and fill it up as much as possible at one time to prevent too long time to add water , The radiator freezes. After filling up the water, start the vehicle and run at idle speed. At this time, because the lubrication is not enough, in order to prevent the engine from pulling the cylinder and damaging the parts, don't slam the throttle. When the temperature rises to 70 degrees Celsius, start the walking vehicle again.
