Car water pump:

Discover how to detect when it's time to replace your auto water pump.

Telltale signs of impending automotive water pump failure are a whining that changes pitch with engine speed or coolant leaking from the pump itself.

Defective auto water pumps often reveal their failure by coolant leaks in unusual locations.
Automotive water pump replacement can be an average job or a long and involved project depending on your vehicle. Specialized tools needed to complete this task may be required. Please consult your repair manual or an Advance Auto Parts Team Member before attempting this procedure.

Why you should pay attention your faulty auto water pump:

An auto water pump failure can lead to engine overheating, which in turn can result in engine failure. In order for coolant to work properly it needs to constantly flow through your engine. Making it flow is the job of your water pump.

There are a number of different types of water pumps and replacement can vary from average to difficult depending on your vehicle. This is a job that requires a repair manual as well as help with tools and parts selection: all of which you can get from Advance Auto Parts.

Do-it-yourself difficulty guide for replacing an auto water pump:

Estimated time required - 1 - 6 Hours

Save money by changing your own car water pump. Follow these instructions.

Begin with a cool engine, then disconnect the negative battery post and drain your coolant into a catch pan by loosening the petcock on the bottom of the radiator.

  1. Replacement pumps usually come with the gaskets needed for the job. Refer to your repair manual and familiarize yourself with the pump type and location before beginning.
  2. On this car the water pump is well hidden beneath the exhaust manifold. This is a good example of a potentially complex job.
  3. Your vehicle’s repair manual will tell you which components you'll need to remove to get to the car water pump. Here the radiator outlet pipe is being removed from the pump housing.
  4. In this case, the pump housing has to be removed to gain access to the pump itself. Your vehicle may be different. Take things one step at a time.
  5. All surfaces must be cleaned and free of old water pump gasket material and adhesives before reassembly. Coolant leaks may result if mating surfaces are not clean.
  6. Make sure the pump mounting surfaces are also clean and completely free of water pump gasket material and adhesives. Tests fit the auto water pump and visualize assembly before proceeding.
  7. Use RTV silicone water pump gasket sealer and/or a gasket depending on what your repair manual or water pump instructions recommend. Take your time with this step as leaks can result if done improperly.
  8. Install the replacement pump. Refer to your repair manual for proper refastening sequence. Reinstall all removed components. Refer to your repair manual for proper refilling method and coolant mixture.
