1 Engine cooling system
The long-life antifreeze and anticorrosion coolant applied by the engine cooling system can be kept unfrozen above -35℃. If the vehicle has to work in the environment below -35℃, the coolant concentration should be increased appropriately.
Drain off the water condensed in the air reservoir in case of freezing, and note to check the air dryer for working condition.Under normal condition, the service life of desiccant in the air dryer is half a year. If any oil-water mixture is drained from air reservoir, air dryer is ineffective and the desiccant should be replaced immediately.
3 Battery
The battery applied is maintenance-free. If the vehicle will not be used for a long time and the temperature is low, you had better remove the battery and place it in a warm room. Check the battery electrode terminal and conductor connection clamp for looseness and the battery for normal working condition every 500 km.
4 Startup system
Start the engine with an auxiliary startup device under low temperature. Make the electronic heating flange operate with a relay so as to start the engine successfully under -30℃.
5 Parking
In case of cold climate, do not park until remove the load firstly and then make it run at idle speed for 2-3 minutes, and the water temperature and the oil temperature drop. After parking, do not drain the coolant containing anti-freezing additive. If the coolant contains no anti-freezing additive, it is necessary to open the water drain valve or water plug on the engine, the oil cooler cover, the radiator, the water inlet pipe and the like, to drain the coolant to prevent the engine from being frozen.
