Check of a condition of the water pump


1. Failure of the water pump is capable to cause the most serious consequences, up to complete jamming of the engine as a result of an overheat. The defective pump is subject to replacement.
2. Warm up the engine to normal working temperature and, without suppressing it, compress a hand the top hose of a radiator, - if at a hose otpuskaniye in it the liquid push is distinctly felt, therefore, the water pump functions regularly.

Try not to touch with hands a krylchatka of the fan!

3. The water pump is equipped with a control/ventilating opening. In case of epiploon failure from an opening cooling liquid starts to exude. Prepare a pocket small lamp and a small pocket mirror, - the opening is located from below on the pump case, is direct under an assembly axis. Existence round an opening of deposits of brownish color testifies to malfunction of an epiploon, - easy decolouration of a surface (a ring of light gray color) should not cause concern.
4. At failure of bearings of a shaft of the pump in engine operating time in its forward part there can be a howling sound which should not be confused to the whistle published by a driving belt at weakening of effort of its tension. Wear of the bearing can be revealed on existence люфта when rocking a nave/shaft of the pump (do not forget to switch off before the engine and to throw off from a pulley a belt).
5. Even in the absence of external signs of wear the final conclusion about a condition of the water pump can be made only after its removal and more detailed studying.
