Check of a condition of the water pump

Failure of the water pump is capable to cause the most serious consequences, up to full jamming of the engine as a result of an overheat.

There are two ways of check of serviceability of functioning of the water pump without its removal from the engine. The defective pump without fail is subject to replacement on new, or restored.

The water pump is equipped control (or ventilating) with openings (see an illustration below).

.


In case of failure of an epiploon from openings cooling liquid begins to exude. Prepare a pocket small lamp and a small pocket mirror, then uncover a GRM drive belt. By means of a lamp and a mirror find control openings from below on a back part of the pump and check whether liquid exudes through them.

At failure of bearings of a shaft of the pump in operating time of the engine in its forward part there can be a howling sound which should not be confused to the whistle published by a driving belt when easing effort of its tension. Wear of the bearing can be revealed on existence of a side play when rocking a pulley of the pump (do not forget to switch off before the engine).
