How to maintain the truck in winter ?

1. Fuel oil

Diesel vehicles according to the local temperature, timely replacement of appropriate diesel,

Generally, the freezing point of the fuel should be about 5° lower than the ambient temperature, and diesel such as -10#, -20#, -35# and -50# can be selected.

If the freezing point of diesel is too high, it is easy to condense in a low temperature environment, resulting in the normal supply of fuel, affecting the start-up and operation.

2: Engine oil 

The winter temperature is low, the engine gap is large and the lubrication is poor, it is easy to wear, and it is necessary to replace the oil with small viscosity and low freezing point in advance, such as the oil of 10W-30 or 5W-30, which has strong fluidity and better anti-freeze effect.

The right oil can better lubricate the various parts of the engine at low temperatures, reduce wear, and ensure the normal operation of the engine.

3.Hydraulic oil

When replacing hydraulic oil, it is necessary to clean the hydraulic oil tank and replace the hydraulic oil filter. It is recommended to choose HM46# hydraulic oil above -10° and HS32# hydraulic oil below -10° to ensure the normal operation of the hydraulic system.

4.Antifreeze solution

Replacement of antifreeze in winter, according to the manufacturer's model, the engine cooling system needs to be cleaned before filling, antifreeze can not only prevent the engine from freezing in a low temperature environment, but also play a role in heat dissipation and anti-corrosion.

5. Tire

In winter, the pressure arm of the tire is slightly higher than normal, because the low temperature will reduce the pressure of the tire,

Please remove the inclusions in the tire grain in time to prevent foreign bodies from losing the tire.

6. Chassis and rear mounting system

Winter should choose low temperature resistant 2# or 3# butter maintenance, special parts recommended to use molybdenum disulfide butter lubrication,

7. Primary heater unit

In winter, the vehicle is preheated for about 1 minute when starting at about 0°, 1-5 minutes for the hot car at about 10°, and 10 minutes for the hot car at minus -30°.

Mechanical parts in winter expand and shrink, the gap between components is large, the refueling flow is slow at low temperature, and the wear of the engine will be accelerated if the vehicle is started to walk.
