How to replace a water pumps for cars can really be time consuming, but with the aide of several online videos and how-to-videos, it's not completely impossible. Most important thing to do is to make sure that you actually need to replace the pump. Once you have accessed that, then you're ready to go. You can acquire your new pump from dozens of auto parts places or, if your trying to save a little money, you can go to a junk yard and get a used one. The best way is to buy the part brand new, because some of them actually carry a warranty for up to a year or even a lifetime warranty.

Needed parts to perform the replacement include:

  • water pump
  • drain pan
  • socket set
  • wrench
  • owner's manual
  • engine coolant (antifreeze)
  1. Make sure that your car is cut off and cooling so that when you remove the pump, you don't get burned trying to perform the repair. 
  2. Once the car is cooled completely, disconnect the battery of the car. 
  3. Using the drain pan, place it underneath the car and drain out all the coolant in the car's radiator. 
  4. Now, with the fluids completely gone, find your alternator and loosen it so that you can remove the drive belt from the car. 
  5. Now is the time to clear out anything that might be blocking your access to the pump such as a pulley or a fan. 
  6. Disconnect any and all hoses that are attached to the water pump.  
  7. With the hoses removed, remove the screws and bolts that are holding the pump in place. 
  8. With the pump out of the way, now is a great chance for you to go ahead and inspect your engine to see if there might be any additional maintenance needed. Sometimes, just having a rag handy to wipe off parts that are not normally accessible can be handy in doing this.  
  9. Remove and replace any gasket on the pump that might need to be replaced or repaired. 
  10. With your new water pump in hand, go ahead and line it up with the specs outlined in your car's owner's manual. (If you don't have an owner's manual, you can always go online to the manufacturer's website and get the specs there.)
  11. Hook all the hoses back up to the pump and reconnect everything that was loosened or removed.  
  12. The last and final step, with the pump and everything else all placed back together, is to fill the car's cooling system back up (radiator). With this all done, reconnect the battery to the car.  

Now that you have done all this, it's time to fire up your engine and see if it works. Once that's all said and done, then you're motoring now with a new pump that will be more durable throughout the years. Plus, you walk away the knowledge of how to install a water pump.
