Points for attention to replace pumps

[Mengjuan Zhu]

When the pump is damaged, we should pay attention to the following items when replacing.

（1）   The real cause of the pump damage should be clear. Before replacing the pump, the radiator fan, thermostat and coolant should be determined.

（2）   It is likely that pumps with similar shapes but suitable for different types of engines will occur, so before installing the pumps, a comparison should be made between the new pump and the old pump removed, or a check should be made on the part number of the pump and the type of the engine to determine whether the selected pump is suitable for the model being repaired.

（3）   Water pump installation surface should be carefully cleaned and leveled.

（4）   When installing the pump, wet the seal ring with coolant first. If you need to use sealant, be careful not to apply too much.

（5）   Do not use the way of percussion pump shaft to install the pump. You should check the real reason for the difficulty of pump installation. 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 installing bolts in water pumps, they should be tightened progressively in the direction of diagonal according to the prescribed torque, excessive tightening of bolts or causing damage to gaskets.

（6） The tension of the pump belt must be strictly controlled according to the adjustment standard. Excessive tension of the belt, will cause bearing overload operation and early damage; and too small tension, easy to produce noise, serious pump can not work properly.

Feilong Jiangli warm notes: If you can't replace it by yourself, please go to the warehouse.
