Nissan 21010-7S000 Pump Assy-Water

Drain the cooling system after taking note of the coolant warning statement then keep the well-preserved coolant for later reuse. Begin by removing the engine cover together with the air intake duct starting from the throttle body at its point where it meets the air filter housing. Tighten only the mounting fasteners on the water pump pulley by several turns then stop. First remove the drivebelt from the engine before removing the water pump pulley fasteners and actual pulley component. After separating the water pump from the engine using mounting bolt removal you should inspect its impeller backside for corrosion signs and damaged fins. Examine the two pumps to verify precise similarity between them. Fasten the pump to the engine smoothly before tightening the bolts finger-tight. The engine needs to be clean from all old gasket remains before starting this process. Gradually increase the bolt torque until specification without forcing it beyond stated limits since excessive torque could warp the pump. Replace all parts which needed removal during pump access and carry out a cooling system refilling and bleeding procedure. Use the engine to check both leak detection and operating system functionality.
