Engines 1.5 l and 1.8 l
Removal
1. The details of the water pump installation on 1.5 l and 1.8 l engines are shown in the illustrations.
2. Disconnect the negative cable from the battery.
If your car stereo system is equipped with a security code, make sure you have the correct combination to activate the audio system before disconnecting the battery!
3. Drain the cooling system.
To avoid burns, proceed with the above work only after the system has completely cooled down! Do not allow antifreeze to come into contact with exposed areas of the body or painted surfaces of the car. Wash off any accidental splashes immediately with plenty of water. Remember that antifreeze is a highly toxic liquid and its ingestion, even in small quantities, can have the most serious consequences (even fatal). Never leave antifreeze stored in a loosely closed container and immediately collect any coolant spilled on the floor. Remember that the sweet smell of antifreeze can attract the attention of children and animals. Consult any car service station for information on how to dispose of used coolant. In many regions of the world, special collection points for various types of waste have been set up. Never pour old coolant down the drain or onto the ground!
4. Remove the crankcase protection elements.
5. Loosen the power steering hose clamp bolt.
6. Remove the accessory drive belts.
7. Support the engine with a trolley jack and remove the powertrain suspension support bracket.

9. Remove the steering pump support bracket.
10. Remove the generator support bracket.
11. Remove the mounting bolts and the water pump assembly, its sealing gasket, and the sealing ring of the water inlet pipe connector(s).
The water pump mounting bolts are different lengths, so try to remember the exact location of each fastener.
Installation
1. Thoroughly clean the mating surfaces of the water pump assembly and engine block, then wipe them with a rag soaked in acetone.
2. On 1.5L models, install a new O-ring into the receiving groove on the front of the water inlet pipe.
The ring is installed dry, without the use of any oils or lubricants! It is only permissible to slightly moisten the ring with water before installation.
3. On 1.8L models, apply a continuous bead of sealant 2.5÷3.0 mm thick to the mating surface of the pump, then press the pump assembly onto the engine, screw in and tighten the mounting bolts to the required torque (24 N·m).
The pump must be installed within no more than 15 minutes after applying the sealant! The cooling system can be filled and the engine can be started no less than an hour after installing the pump!
4. On 1.5L models, install the water pump assembly onto the engine (remember to replace the sealing gasket), install the mounting bolts and tighten them to the specified torque (25 Nm) - be careful not to allow the pump assembly to move while tightening the fasteners.
5. Installation of the remaining components is carried out in the reverse order of their dismantling.
6. Fill the system with fresh coolant.
7. Reconnect the battery, start the engine, warm it up to normal operating temperature and correct the coolant level in the radiator. Check the cooling system for signs of developing leaks.
8. After the engine has cooled down, check the coolant level again.
