What issues should be noted in winter semi-trailer maintenance
The harsh winter climate leads to a decrease in the fluidity of fuel,an increase in the viscosity of lubricating oil,and a tendency for cooling water to freeze.Therefore,using a semi-trailer in harsh winter conditions,if the method is not appropriate,can reduce the service life of the semi-trailer and even cause accidents.In this regard,Liangshan semi-trailer manufacturer puts forward the following suggestions for the protection and use of semi-trailer during this season.
Wash the vehicle with warm water
In winter,it is not allowed to directly flush the semi-trailer with cold water.It is particularly important not to directly flush the engine,as after the engine heats up,the temperature at the front of the car is high,and cleaning with cold water can cause rapid cooling,which can cause significant damage to the surface paint.After washing the car,you should open the window and dry the surrounding area to avoid residual water and freezing at the door gap,which may freeze the car door.When the car window is frozen,do not forcefully open or close it.Pay special attention to the electric window and wait for the ice to naturally melt before using it.
Engine oil should be replaced with winter oil in a timely manner
The viscosity of engine oil varies with temperature.As the temperature decreases,the fluidity of the engine oil will deteriorate,and the engine's engine performance,power,and economy will also significantly decrease.Therefore,it often leads to difficulties in cold starting.During winter,it is recommended to replace the oil in the oil pan and air compressor with winter grade oil in a timely manner;Replace the gear oil in the transmission,transfer case,differential,and steering with winter gear oil;After cleaning the wheel hub bearings,use lubricating oil with lower viscosity for the bearings.
Batteries should be replaced promptly after 3 years of use
Eliminate oxides on battery electrode posts,compensate for distilled water,and maintain normal voltage and liquid level.When driving,burn the engine first to make it work before turning on the lights,radio and other electrical appliances.When parking,turn off various electrical appliances first and then turn off the engine.The lifespan of a typical battery is two to three years.Assuming it is close to its service life,replace it with a new one.
If ordinary water has been involved in the antifreeze,it is necessary to replace it
Vehicles using water as coolant should first clean the engine cooling system to remove impurities such as scale,and then add antifreeze according to the prescribed ratio.If ordinary water has been involved in antifreeze before,it is necessary to replace the antifreeze.The price of antifreeze is not expensive.Domestic antifreeze costs about ten yuan per barrel,and higher quality antifreeze costs around a hundred yuan.A car basically requires a bucket of antifreeze.The winter night temperature in Beijing is generally below zero degrees Celsius,so glass water should also be replaced with antifreeze winter glass water.Perhaps adding an appropriate proportion of alcohol to the glass water can also achieve the intention of lowering the freezing point and preventing freezing.
Wiping the inner surface of the windshield can prevent fogging
Before entering winter,it is important to inspect heating equipment such as windshields,side window vents,and rear window heaters to ensure they are in excellent condition,in order to avoid icing and frosting on car windows during winter,which can obstruct visibility and affect safety.To quickly defog,turn on the air conditioning switch;The use of specialized glass anti fog agents also has excellent effects;Assuming there is no dedicated glass anti fog agent,household glass cleaning agents or detergents can be used instead to wipe the inner surface of the windshield,which can also have an anti fog effect.
