Instruction. The presence of liquid droplets or traces of vapor at the air outlet of the coolant pump should not cause concern, if this does not lead to more significant fluid loss.
Removing
Disconnect wire "masses" from the battery.
Drain the coolant into a container. Then immediately connect and secure the hose.
Remove V-belt.
Remove the front toothed belt cover.
Loosen toothed belt.
Loosen the coolant pump mounting bolts and remove the pump.
Installation
Clean mating surfaces of pump and cylinder block.
To prevent corrosion of the pump, it is necessary to lubricate the mating surfaces with silicone grease, for example, Opel 1970206 (901763530). A rusted pump prevents it from turning to tension the toothed belt.
Install the water pump with a new gasket on the cylinder block.
Attention! Screw in the bolts by hand.
Put on and tension the toothed belt.
Tighten the pump mounting bolts: for engines with a volume of 1.4 and 1.6 l - to a torque of 8 Nm (bolts M6), for engines with a volume of 1.7, 1.8 and 2.0 liters - a torque of 25 Nm (M8 bolts).
Install the front toothed belt cover.
Put on and tighten the V-belt.
Fill with coolant.
Connect wire "masses" to the battery.

Removing
Unscrew the four nuts securing the coolant pump pulley, remove the pulley.
When loosening the nuts, keep the pulley from turning with Hazet 2170 (С7265).
While holding the crankshaft center bolt with a spanner wrench, remove the pulley bolts. Remove pulley.
Loosen the coolant pump mounting bolts and remove it from the cylinder block together with the impeller cover.
Installation
Insert the impeller cover into the cylinder block.
Insert the coolant pump with a new gasket into the cylinder block and tighten its bolts to 10 Nm.
Install the crankshaft pulley and tighten its bolts to 10 Nm.
