Engine 1.8-I / 125 hp
The water pump is located in the cylinder block and is driven by a toothed belt.
Withdrawal
Drain the coolant
Remove poly V-belt.
Unscrew the three bolts securing the V-ribbed belt tensioner and remove it.
Set the piston of the first cylinder to top dead center on the compression stroke, loosen the tension of the toothed belt and remove it from the camshaft pulley and water pump. The vibration damper and the lower toothed belt cover can be left in place.
Attention. To protect the toothed belt from coolant, cover the toothed belt with rags or polyethylene.
Unscrew bolts 1 and remove water pump 2 with O-ring 3 (pic. 3.28).
Turning the water pump shaft, check the condition of the water pump bearings and, if necessary, replace them.
Installation
Clean the seat of the O-ring.
Soak the new O-ring in coolant.
Install the pump so that the drain hole on the pump housing is at the bottom.
Screw the pump with bolts, tightening them with a torque of 15 Nm.
Install the toothed belt.
Install and bolt the V-ribbed belt tensioner to 25 Nm.
Install poly V-belt.
Pour coolant into the cooling system and bleed air from the system.
Engine 1.8-I / 150 hp
The water pump is attached to the cylinder block along with a bracket with alternator, power steering pump and radiator fan.
Withdrawal
Remove the thermostat.
Attention. The V-ribbed belt for the A/C compressor drive must not be removed.

Unscrew the bolts and remove the water pump from the bracket.
Installation
Turning the water pump shaft, check the condition of the water pump bearings and, if necessary, replace them.
Attention. If the paper pad 2 has been replaced (pic. 3.30) or bearing housing 1 with impeller, screw the pump cover with bolts, tightening them with a torque of 10 Nm.
Install the water pump with a new sealing ring and bracket on the engine block and, in accordance with the previously marked marking, screw in the bolts, tightening them with a torque of 25 Nm. Tighten bolts in sequence 1-6 (pic. 3.29).
Screw the front toothed belt cover to the water pump housing.
Install thermostat.
Connect the cooling system hoses to the water pump and secure them with clamps.
Fit the suction pipe bracket and secure it with the bolts, tightening them to 25 Nm.
Install and bolt the V-ribbed belt tensioner to 25 Nm.
