Though it is thermal energy where engine primarily generates mechanical power, extremely high level of temperature can damage the system. Essentially, the amount of heat being produced through the combustion process must be regulated. The responsibility of maintaining the right temperature level of engine operation is taken cared of by the engine cooling system. It uses a catalyst through which the unnecessary thermal energy collected within the powerhouse is transmitted outside and dissipated.

A certain amount of heat is needed in order to start your Nissan engine. At that particular point, the amount of temperature is very minimal that the job of the engine cooling system is still unnecessary. After the engine has been set to life and progress in operation, its heat level will as well start to increase. When it reaches the temperature rate of normal operation, the cooling system will automatically begin doing its duty. The catalyst better known as coolant, the radiator, coolant expansion tank, thermostat, heater or AC blower motor, hoses, radiator fan, fan belt, and water pump will work together to accomplish the job.

The Nissan water pump is the component which enables the continuous circulation of the coolant between the cooling system and the engine. Operationally, the mixture of coolant and water which is being held by the radiator is forced by the water pump to travel through a hose so to reach the engine block. While traveling across the engine block, the catalyst will gather the excess heat, and then move to another hose leading it back to the radiator where the actual heat dissipation would take place.

Water pumps are of several types with different applications and designs. There's the impeller type, water pumps featuring spring-loaded seal, and those that carry pre-packed ball bearings with sealed ends. The first one makes use of a rotating impeller to force the coolant towards the engine block. That impeller requires rapid rotation, causing its drive belt to easily get damaged and consequently allow slippage while in operation. The second one primarily works best in preventing coolant leakage around the pump shaft. The last one on the other hand, is the modern type of water pump especially designed to eliminate the need of lubricant. Perhaps you're looking for any of these water pumps for your Nissan.
