The water pump is a part of cooling system and it serves to provide the cooling liquid circulation in the channels of the engine jacket.

By drive type:

• Belt-driven;
• Gear driven.

By location:

• outbound;
• inbound.

The impeller is the central part of the water pump. The part is driven by the drive shaft. The blades differ in shapes and can be set straight, curved, or tangential or radial. The size of the impeller is directly proportional to the unit capacity. In engine operation fluid flows to the rotating impeller, and due to the centrifugal force is directed to the cooling jacket of the engine.

On the average, the part’s life cycle is 120 000 km. Using coolant of high quality, you can increase the service life time. It is recommended to use rain or melt water or a special liquid containing at least 40% ethylene glycol to prevent scale deposits and freezing during cold weather.

• pump leakage;
• corrosion;
• damage to the flange of the pump housing;
• bearing wear;
• failure of the impeller.

• engine overheating;
• increased noise during operation of the component;
• bearing play;
• traces of coolant leakage.

• incorrect installation;
• wear of the part;
• use of low-quality coolant;
• system depressurization;
• long-term load of the engine.

Since the element consists of a number of rotating parts, repair is done by their replacement in case of failure. Water Pump is a complex structure, so without knowledge and experience it is best to seek the help of a service center. You can replace the item by yourself, following these instructions:

• deenergize the car by removing the battery terminal "-";
• drain the coolant, opening the radiator drain valve;
• remove the belt, generator and water pump pulley;
• for removing the pump, disconnect hoses;
• get the mounting surface clean from the remains of gasket materials and apply some sealant in place of contact;
• install a new gasket;
• follow the above steps in reverse order;
• start the engine and check the pump surrounding area for leaks.
