5.12.5. Replacement of the water pump

The pump remove for repair or replacement at occurrence during its work of the noise which level exceeds usual, and leaks of a cooling liquid.
Pump dismantling labour-consuming enough, therefore we recommend to replace at malfunction the pump in gathering.
The key-shestigrannik «on 5» is required to you.
1. Merge a liquid from cooling system («Replacement of a cooling liquid» see).
2. Remove a drive belt газораспределительного the mechanism and a tension roller (Replacement and adjustment of a tension of a belt of a drive газораспределительного the mechanism see «and replacement of its tension roller»), the bottom and back covers of a drive газораспределительного the mechanism (Removal and installation of the oil pump »see«).
3. Turn out three screws of fastening of the pump to the block of cylinders and remove the pump together with a rubber sealing ring.

    
GOOD ADVICE
At each removal of the water pump it is recommended to replace screws of its fastening new as they are subject to oxidation and after long operation can break off at a reversing. Besides, a nest in a screw head under шестигранник rather small and its sides at a screw reversing are rumpled. At an inhaling and a repeated reversing of the screw its damaged sides can be crumpled absolutely, and will turn out the screw very inconveniently. For the prevention of "souring" of screws grease their carving анаэробным with a carving clamp.

4. Remove a sealing ring from the pump case.

    
GOOD ADVICE
We recommend to replace at each removal of the pump a sealing ring new.
Before installation of the pump for hermetic sealing of connection and prevention of sticking of a sealing ring grease a ring with technical vaseline.

5. Establish the pump in a nest of the block of cylinders, сориентировав its case проточкой (it is shown by arrows) at a case end face upwards, and fix screws.
6. Establish details in an order, the return to removal.
