To replace the water pump on a car, you will need: all the tools needed to remove the camshaft drive belt and idler pulley, as well as wrenches «on 10», «at 17», two screwdrivers.
1. Disconnect the wire from the terminal «minus» battery.
2. Drain the coolant from the cooling system (see «Coolant replacement»).
3. Set the piston of the 1st cylinder to the TDC position (see «Setting the piston of the first cylinder to the TDC position of the compression stroke»).
4. Remove the tension roller (see «Timing belt replacement (camshaft drive) and tension roller»).
5. Remove the camshaft sprocket (see «Replacing the cylinder head gasket»).
6. Turn away a nut and a bolt of fastening of a back cover of a drive of a camshaft...
7.... and three water pump mounting bolts (these bolts also secure the cover) and remove the rear camshaft drive cover.
8. Inserting a screwdriver into the groove, carefully separate the water pump from the block and remove it.
9. Remove the gasket from the water pump.
10. Replace the water pump if coolant is leaking from the drain hole (damaged water pump seal).
11. Replace the water pump if there is noticeable end play in the water pump shaft (damaged water pump bearing)...
12. Replace the water pump if cracks, chips, spalling are found on the impeller 1, toothed pulley 2 and housing 3 of the water pump.

14. Install the water pump on the Lada Kalina car in the reverse order of removal.
15. Establish on the car other details in an order, the return to removal. Install the camshaft pulley with the protruding part of the hub towards the engine. After that, check the coincidence of the TDC marks on the camshaft pulley and the rear cover of the drive belt (see «Setting the piston of the first cylinder to the TDC position of the compression stroke»). Adjust timing belt tension (see «Timing Belt Tension Adjustment (camshaft drive)») and fill the engine cooling system with coolant (see «Coolant replacement»).
