Your water pump is a major component of your engine cooling system. If the water pump fails, the engine will overheat causing it to shut down. Water pumps have an indicator that tells you when they are going bad. There is a small hole in the water pump right under the shaft in the middle that the pulley bolts to. As the water pump's bearings wear out coolant seeps by them and leaks through this hole. If you notice a few drops of coolant under the front of your engine this is an indicator your pump is failing. If a water pump fails it will cause engine overheating, and possibly further engine damage. If you have noticed little drops of coolant under the front of your vehicle then inspect the bottom of the water pump to see if it is dripping out of the indicator hole. If your water pump is the problem, then this part is for you. Replace your broken or leaking water pump now with this great fitting replacement part.

Nissan Water Pump
I have a Commercial and Residential painting company and this part was for a company vehicle. The cost of the water pump was dramatically less than the local auto parts suppliers were asking. The FREE shipping was a plus as well. It took a few days longer than if I had purchased it locally but the savings was well worth it! I will use 1A Auto in the future for my fleet repairs!
