A 7.3 Powerstroke water pump rebuild can be a challenging task, but it’s not impossible. With the right tools and a little bit of know-how, you can save yourself a lot of money by rebuilding your water pump instead of replacing it. In this post, we’ll explore the different options for rebuilding a 7.3 Powerstroke water pump and give you some tips and tricks to make the process as smooth as possible. So let’s get started and dive into the world of water pump rebuilding!
Tools and Materials Needed
- Socket wrench
- Ratchet and sockets
- Flathead screwdriver
- Replacement parts
Disassembling the Water Pump for 7.3 Powerstroke Water Pump Rebuild
To remove the water pump cover:
- You’ll need to loosen and remove all of the bolts holding it in place.
- The inlet tube is also held by several bolts that you’ll need to loosen before removing it completely.
- Once all of these have been loosened and removed, you can take off your pulley by unscrewing it from its shaft with a wrench or socket driver.
- You will then be able to pull out your impeller using pliers or another tool suited for gripping small objects tightly (like needle-nosed pliers).
- Finally, remove any remaining parts until only one piece remains: the bearing housing assembly!
Cleaning and Inspecting the Parts for 7.3 powerstroke Water Pump Rebuild
Now that you have the parts, it’s time to clean them up and inspect them for any damage.
- The first step is to wash the parts in hot soapy water.
- Next, use a degreaser like Simple Green or mineral spirits (paint thinner) to remove any remaining dirt or grime from the surface of each part.
- Once you’ve cleaned all of your new water pump components, it’s time to inspect them for any signs of damage or wear. If there are any cracks or gouges in either housing halves, discard those pieces and get replacements from another source before continuing with this guide!
- Measure each housing half’s thickness at several points around its circumference using calipers; if there are no measurable differences between these measurements then congratulations–your new housings should be ready for installation!
Reassembling the 7.3 Powerstroke Water Pump for Rebuild
- Install the bearing.
- Install the impeller.
- Reattach the water pump cover, then install it on your engine and tighten down all bolts to spec (14 ft-lbs).
Testing the New 7.3 Powerstroke Water Pump for Rebuild
To test the water pump, you’ll need to check for leaks and make sure that it’s working properly.
- Check for leaks by spraying soapy water around the pump. If there are any bubbles or wet spots, you’ll know that you have a leak.
- Test your engine for overheating by monitoring coolant temperature gauges (or if you don’t have one, use a thermometer). If there’s no change in temperature after 30 minutes of driving at highway speeds with AC on high and heavy load off-road conditions (such as going up steep hills), then it’s possible that your radiator is clogged with mud or debris from driving over rough terrain–in which case we recommend replacing your radiator cap.
Another option if the rebuild does not work, you may end up considering upgrading to a new water pump for your 7.3 powerstroke. See our guide on the best water pumps for 7.3 Powerstroke.
Preventing Future Problems
- Regularly inspect and maintain the water pump.
- Replace worn parts as soon as possible.
- Use high-quality parts for replacements, even if it means paying a little more than you might be used to paying for replacement parts.
Common Problems with 7.3 Powerstroke Water Pumps
The water pump is one of the most important components in your engine, and it’s also one of the most commonly replaced. The following are some of the common problems that can cause your water pump to fail:
- Misalignment
- Tension issues
- Debris in the system or around the impeller (the part that pumps coolant)
- Corrosion on internal parts of the pump due to coolant leaks or corrosion from old coolant
- Wear and tear over time
Detecting 7.3 Powerstroke Water Pump Problems
- Inspect the impeller. It should be clean and free of any damage, such as cracks or dents. If you notice any issues with your impeller, it may be time to replace it before more serious damage occurs.
- Check for leaks. Leaks can occur at either end of the water pump–in other words, from where it attaches to either side of the engine block or from where coolant flows out into its housing unit (if applicable). If there are visible signs of coolant coming out anywhere along these lines, then you’ll want to get this fixed immediately because it could mean that your entire system is about to fail completely!
- Listen for noises while driving at high speeds over rough roads–this will help give you an idea as whether or not something isn’t quite right with how things are working inside your engine bay yet hasn’t broken down completely yet due simply being old age related wear & tear issues
