First, check the brake and tire wrecker tow truck
In winter, the brake is particularly important. If you find a dead or deviation brake, tire tread wear serious, it should focus on the correction or replacement.

Second, wrecker and maintenance of the engine cooling system

1, check the thermostat a variety of conditions to ensure that the thermostat is working well, to prevent the engine water temperature is too low or too high. The engine is often running at a low temperature, it will lead to increased mechanical wear.

2, clear water jacket scale. The engine water jacket cleaning, remove the internal scale to prevent the excessive accumulation of scale, affecting the engine cooling make machine temperature is too high, such as scale from clogging the drain switch, turn on the water does not lead to a net.

3, add antifreeze. The temperature is too low and the conditions do not allow, you can use antifreeze in the cooling system before using thoroughly cleaned, and should choose a good quality, low corrosive antifreeze fluid, antifreeze quality time and avoid corrosion of parts Chang Jie sprinkler phenomenon.
Third, replacement of various oil, buy a new wrecker go back a month to replace the hydraulic oil;
1, the use of low pour point, good mobility fuel. Low temperature fuel viscosity increase, fluidity, atomization bad, easy to make the combustion process of deterioration of fuel, the engine startability, dynamic force significantly decreased, and therefore, in the case of conditions should be used in low pour point fuel. The general principle is that the choice of fuel pour point lower than the ambient temperature of about 5 ℃.

2, change the oil. Selection smaller viscosity engine oil, at low temperatures, the viscosity of the engine oil increases as the temperature drops, fluidity, and therefore should be replaced by smaller viscosity oil to compensate or eliminate such adverse effects.

3, the replacement of winter with various oils and greases. Into the winter response transmissions, speed reducer, steering gear switch to winter oil, wheel bearing grease replaced with low drop point.
