Welcome Message from 1A Auto

This water pump is a new replacement part that has the following specifications.


  • New not remanufactured
  • Replaces one of many dealer part numbers including: 12456113, 12458935, 12556449, 88894290, 89017439, 8890174390
  • Includes water pump pulley
  • Built to strict quality control standards
  • No core charge

Note: On 2003 and older models, if your thermostat housing does not fit, you may need to purchase a 2004 and newer thermostat housing. This is due to new design changes in the replacement water pump.

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.
