What is the use of the cooling system in your Nissan Altima if there is no water pump? The function of the cooling system is to manage the engine temperature. This cooling component pumps the engine coolant from the radiator to the engine and back again. It is the key to the proper circulation of the coolant. It is situated close to the engine and is operated by a drive belt. If not for the water pump, the essence of the cooling system will be gone. Using a water pump is essential to allow the successful circulation of the engine coolant for heat gathering. Given that the engine releases uncontrollable heat at times, this heat has to be managed as much as possible to keep the engine from overheating. To dissipate the heat effectively, coolant needs to be circulated, and this can be successfully done with a pump. For the busted pump of your 1996 Nissan Altima, the NPW Water Pump is the most appropriate alternative. The NPW Water Pump is associated with a great design for optimal performance.
