Check of functioning of the water pump

Failure of the water pump can be at the bottom of the serious damages of the engine connected with its overheat.

There are some ways of check of functioning of the water pump without its removal from the engine. If the pump is faulty, it is necessary to replace it new or restored.

Water pumps are equipped control or ventilating with openings. In case of failure of an epiploon of the pump from an opening the cooler starts to exude. In most cases to find and examine a control opening which is in the lower part of the pump, the small lamp is required.

At emergence of malfunction of an epiploon of a shaft of the water pump from its control opening the cooler starts to exude.

If bearings of shaft of the water pump are faulty, they can publish howl, which will start with a forward part of an impellent compartment at operation of the engine. Wear of a shaft is shown in the form of palpation up-down a pulley of the water pump. Do not confuse howl, published by bearings with the squeal which is taking place at a proskalzyvaniye of a driving belt.

Grasp a flange of the pump try to shake its shaft up-down for identification of signs it люфта.

There is a probability of an exit of the pump out of operation when it is not accompanied by characteristic signs (howl also cooler infiltration through a control opening). Corrosion of a back part of shovels of a rotor of the pump, giving in a certain stage of the development to inadmissible decrease in efficiency of functioning of the pump sometimes takes place. The only way to check the such assumption removal of the pump and careful research of its condition is.
