1. Drain the liquid from the cooling system (see «Coolant replacement»).
2. Remove the timing belt, tension roller (see «Replacing the timing belt and its tension roller»), support roller and rear timing cover.
3. Turn out three bolts of fastening of the pump to the block of cylinders...
4.... and remove the pump along with the rubber sealing ring.
Helpful advice: Each time the water pump is removed, we recommend replacing its fastening bolts with new ones, as they are subject to oxidation and, after prolonged use, can break off when turning out. In addition, the socket in the head of the hexagon bolt is relatively small and its edges are crushed when the bolt is turned out. When tightening and re-twisting a bolt with damaged edges, they can be completely crushed, and it will be very difficult to unscrew the bolt. For a warning «souring» bolts, lubricate their threads with Loctite or similar.
5. Remove the O-ring from the pump housing.
Helpful Hints: We recommend replacing the O-ring with a new one every time the pump is removed.
Lubricate the O-ring with petroleum jelly before installing the pump to seal the connection and prevent the O-ring from sticking.
6. Install the pump in the seat of the cylinder block, orienting its body with a groove (shown by arrows) at the end of the body up, and secure with bolts.
7. Install the parts in the reverse order of removal.
8. Adjust the tension of the timing belt (see «Replacing the timing belt and its tension roller»).
9. Wash down the coolant (see «Coolant replacement»).
