The water pump is not subject to maintenance during its entire service life. If it loses its tightness or makes grinding sounds, it must be replaced - repair is impossible.
Tip: The water pump may fail due to a leak. At first, it sometimes drips from the housing, but within a very short time, the coolant flows out in large quantities. Therefore, if you find a leak in the pump, immediately take care of replacing it.
Removing the water pump
Drain the coolant into a container.
Loosen and remove the alternator poly-pin belt, see chapter "Generator".
Set the engine to TDC position of the 1st cylinder.

Clean the sealing surface on the engine block.
On the water pump, apply a small amount of silicone grease to the sealing surface and the new O-ring.

When applying the timing belt, be sure to take into account the valve timing.
Tighten the timing belt and check its tension.
Tightening torque of the water pump in the 1.6 l engine is 8 Nm; in 1.8 and 2.0 l engines – 25 Nm.
