How to Fix the Inlet Tube on a 7.3 Powerstroke Water Pump?

Fixing the inlet tube on a 7.3 Powerstroke water pump can be a daunting task, but with the right tools and a bit of know-how, you can easily get your engine running smoothly again. If you’re experiencing issues with your water pump, such as overheating or low coolant levels, a faulty inlet tube could be the culprit. In this post, we’ll take you through the step-by-step process of fixing the inlet tube on your 7.3 Powerstroke water pump, so you can get back to driving with confidence. So grab your wrench and let’s get started!

Diagnosing the Inlet Tube Problem on a 7.3 Powerstroke Water Pump

Before you get started, it’s important to make sure that you have a good idea of what’s going on with your truck. If there are visible signs of damage or wear on the water pump inlet tube, then it may be time for a replacement. Similarly, listen for any hissing sounds coming from under the hood when the engine is running. This could indicate that there is air trapped in between various components of your cooling system and needs to be released before proceeding further with repairs.

If everything checks out okay so far (and if you haven’t already done so), now would be an excellent time to check coolant levels by removing one or both hoses leading into either side of your radiator cap–if they’re leaking coolant onto hot surfaces such as exhaust manifolds or headers then this will cause them to warp over time which could lead up being costly repairs later down road!

Tools and Materials Needed

  • Socket wrench
  • Ratchet and sockets
  • Flathead screwdriver
  • Replacement inlet tube

Remove the Old Inlet Tube in 7.3 Powerstroke Water Pump

  • Disconnect the negative battery cable.
  • Remove the water pump cover.
  • Loosen and remove the bolts holding the inlet tube in place, then pull it out of its mounting bracket.

Install the New Inlet Tube in 7.3 Powerstroke Water Pump

Now that you have the new inlet tube, it’s time to install it. You’ll need to clean the area around where the old one was and make sure it’s free of any debris. Then, follow these steps:

  1. Install your new inlet tube by connecting it back into place with its two bolts and nuts (this is where you’ll use those extra ones from step 1). Use a wrench or pliers if necessary.
  2. Re-attach your water pump cover using a socket wrench or screwdriver as needed (you may need both depending on how tight they’ve become).

Test the New Inlet Tube in 7.3 Powerstroke Water Pump

After you have installed the new inlet tube, it is important to check for any leaks. You can use soapy water or a leak detection solution to do this. If there are no leaks, then your job is done!
If you did find some leaks after installing the new inlet tube, then you’ll need to go back and check everything again before moving forward. It’s possible that something was not tightened enough or maybe even missed altogether during installation.

Common Problems with Inlet Tubes

The inlet tube is a common source of problems with the 7.3 Powerstroke water pump. It can be misaligned, too tight, or even worn out. Here are some common issues you might encounter:

  • Misalignment – The most common problem with this part is that it’s not aligned properly when you put it back together. This can cause air leaks and other issues like overheating or poor cooling performance from your truck’s engine compartment.
  • Tension Issues – If there isn’t enough tension on the rubber gasket that holds everything together inside your 7.3 Powerstroke’s water pump assembly, then it will leak coolant through cracks between parts where they rub against each other during operation (such as at threaded connections). 
    • This type of leak may also lead to overheating issues because there isn’t enough pressure inside your cooling system to keep everything flowing smoothly throughout its entire length–and thus less heat gets removed from critical components like head gaskets!


The inlet tube on a 7.3 Powerstroke Water Pump is an important part of the cooling system. It’s responsible for bringing coolant into the engine, so if it’s damaged, you could have serious problems with overheating and other issues. Proper maintenance is key to avoiding costly repairs and ensuring that your vehicle runs smoothly for years to come.
