Precautions for the installation of water pump

(1) the real reason for the damage of the water pump should be clearly defined. Before the pump is replaced, it is necessary to determine whether the radiator fan, the thermostat and the antifreeze are problematic.

(2) it is possible to have a water pump with similar shapes but only for different types of engines, so the new water pump should be compared with the old pump before the water pump is installed, or the part number of the pump and the model of the engine should be checked in order to confirm whether the selected water pump is suitable for the model. 

(3) When installing the water pump, it is necessary to wet the pump sealant ring with coolant first. If you need sealant, be careful not to apply too much sealant. Do not apply grease for ease of installation. This will corrode the sealing ring and cause leakage of coolant.

(4) Do not use the method of percussion pump shaft forced installation of the water pump, should check the pump installation difficulties of the real reason. If the excessive scale in the cylinder water channel leads to the difficulty of pump installation, steel wire brush or fine sand paper should be selected according to the scale situation. When tightening the pump mounting bolts, it should be gradually tightened according to the prescribed torque according to the diagonal direction. Excessive tightening can easily break the bolt or cause damage to the gasket.

(5) it should be emphasized that the belt must be adjusted strictly according to the adjustment specifications for the need to adjust the tightness of the transmission belt. If the pump is damaged in a short period of time after the replacement of the new transmission belt, the tightness of the belt should be checked after removing the cause of the pump itself, and it should be checked whether the belt will always work in the same plane.
