Let's look at the engine cooling system first.

The engine usually uses pressure circulation water cooling system. It consists of water pump, water storage tank, radiator, thermostat, fan and so on.

The abnormal operation of the cooling system will cause engine overheating, resulting in power drop or sudden explosion, and even lead to piston cylinder, cylinder and other bad results. The abnormal working of the cooling system is related to the leakage of the cooling system or the poor working of fans, water pumps, and radiators.

1. The cylinder head, cylinder block and cylinder cushion are leaking due to the loosening of the connecting bolts and cylinder head bolts; The joint surface of the cylinder pad, cylinder head and cylinder block is dirty, corroded or burr, which prevents the joint from being pressed. The bending or deformation of the joint surface will also make the cover, pad and body can not be compressed; By the lower cylinder head or cylinder body overheating or freezing, crack and water leakage; The cylinder head channel is blocked and cannot circulate well, causing the engine water temperature to be too high.

a. The water pump leaks. The water pump is loose or improperly installed or damaged. The pump housing has cracks or sand holes and deformation; Pump shaft bent or shaft sleeve and shaft wear loose, bearing loose.

b. Water leaks from the radiator and heat dissipation tube. Water leakage due to freezing crack or corrosion; The radiator is improperly installed and deformed; The fan is close to the radiator and the radiator is damaged. Water drain plug or drain switch leakage; The core of the radiator is blocked and can not circulate up and down, so that the water accumulates in the upper water storage chamber, resulting in the outflow of cooling water overflow; Connecting hose for a long time, due to corrosion and penetration or crack; Loose hose, hose installation position and leakage.

2 Lack of cooling water due to water leakage or evaporation and the water surface is low and insufficient, causing the engine water temperature is too high.

3 Fan belt too loose belt long-term use, due to corrosion deformation; Belt pulley wear or pump shaft deformation will also make the belt loose, will cause the fan does not rotate or the speed is low, so that the radiator cooling is not good, thus causing the coolant temperature is too high.

4 pump lost pump water action pump shaft wear and bend, pump bearing oil shortage, so that bearing wear and loose; The impeller fixing pin or the impeller fixing bolt loose, the impeller piece is broken, the gap between the impeller and the pump shell is too large, the impeller is blocked by mud or other debris; The suction of the pump decreases and the pressure is insufficient, which affects the circulation effect of the water. Pump tube blockage, water can not flow will make the pump does not pump water, cause the engine temperature is too high.

5 thermostat damage and failure thermostat damage, start for a long time overload operation, the temperature is too high, such as expansion cylinder rupture, the valve can not open and close normally, too much scale, the main valve stuck, the valve does not work, cooling water only small circulation, can not be large circulation with the radiator, so the water temperature is too high.

6. The accumulation of scale, rust and impurities in the radiator causes the blockage of the pipe and heat sink core pipe, hindering the circulation of water flow; Radiator core tube rupture and water leakage; Upper and lower water chamber due to corrosion and formation of spots, holes or cracks and water leakage; Tube core and upper and lower welding parts loose; Other parts due to collision damage, water leakage, etc., will cause the engine water temperature is too high.

7 Too much rust or scaling in the cylinder water jacket because the cylinder in the long-term use of the water jacket deposited sediment, scale or rust, reduce the volume of the water jacket, reduce the flow of cooling water, affect the circulation of cooling water; Due to the poor thermal conductivity of the scale layer, the cooling effect is reduced. The accumulation of scale over time will also block the water jacket, pump inlet, radiator, hinder the circulation of water, which will make the engine temperature too high.
