Removal the water pump (VAZ-21099)

The main defects of the water pump:

• 1. Coolant leak from the pump.
• 2. Wear of the pump bearing, as evidenced by increased noise during its operation.

Before you begin: Disconnect the wire from the "–" terminal of the battery and drain the coolant (see subsection 11.5.7.).





Mounting points for the rear camshaft drive cover and water pump.

Caution! After removing the camshaft drive belt, do not turn the camshaft or crankshaft, otherwise the pistons may hit the valves.

1. Loosen the three bolts securing the front camshaft drive cover and remove it.





2. Set the piston of the first cylinder to TDC. To do this, turn the crankshaft by the crankshaft pulley mounting bolt so that the mark on the camshaft pulley is opposite the mark on the rear cover of the camshaft drive.



3. Loosen the tension roller mounting nut and loosen the belt tension by turning the roller.



4. Remove the belt from the camshaft and water pump pulleys.




5. Loosen the camshaft pulley mounting bolt. To prevent the camshaft from turning, insert a screwdriver into the pulley hole and rest it against the rear cover mounting nut.



6. Remove the camshaft pulley using two screwdrivers.



7. Remove the nut and four bolts securing the rear cover (see note).
