Replacing the o-ring on a 7.3 Powerstroke water pump can seem like a daunting task, but with the right tools and a little know-how, it can be a relatively simple process. A worn or damaged o-ring can cause coolant leaks and potentially lead to overheating or engine damage, so it’s important to replace it as soon as possible. In this post, we’ll walk you through the steps to replace the o-ring on your 7.3 Powerstroke water pump, so you can keep your engine running smoothly and avoid costly repairs down the line. Let’s get started!
How to Know if your O-Ring on 7.3 Powerstroke Water Pump Needs Replacement
- Check for signs of damage or wear around where the two pieces connect together (you may be able to see them if they’re worn enough).
- Look at how much play there is between those two parts when they’re put together–if there’s too much movement here then chances are good that some kind of problem exists behind those surfaces where we can’t see them yet!

Removing the Old O-Ring
To replace the O-ring on your 7.3 Powerstroke water pump, you’ll need to drain the coolant from your engine. To do this, remove the radiator cap and let it drain into a pan or bucket. Next, remove any plug wires that are in the way of removing your water pump–you don’t want them getting caught up in anything!
Now we can move on to removing our old O-ring from inside of our water pump housing:
- Remove all bolts holding down bracket (4 bolts)
- Remove bracket from engine block by pulling straight outwards with pliers until it comes free from its mounting holes
Installing the New O-Ring in 7.3 Powerstroke Water Pump
To install the new O-ring:
- You’ll want to lubricate it with some motor oil. This is a good idea because it will help prevent any leaks and make it easier for you to get the old O-ring out of its groove.
- Once you’ve lubed up both sides of your new O-ring, slide one end into place on top of your water pump housing (the side where all those bolts are).
- You may have to use some force here–but don’t worry! Just push down until it clicks into place; if there’s resistance at all, stop pushing immediately and take another look at what’s happening before continuing further down this path. If everything looks good so far: move on!
- Once both ends are in place (and hopefully not hanging off), tighten down each bolt until they’re snug enough not fall out but still loose enough so that they can still rotate freely when needed later down road if necessary due to any changes made during operation such as adding more coolant fluid or replacing parts like gaskets.
Re-Installing the 7.3 Powerstroke Water Pump
When you’re ready, it’s time to re-install the water pump.
- First, align the pump with its mounting holes on the engine block.
- Then use your ratchet and socket set to tighten all four bolts in place.
- Next, refill your coolant system with fresh 50/50 mix coolant/distilled water until full (don’t forget about any overflow tanks).
- Finally, start up your truck and check for leaks around all hoses and fittings before driving off into traffic!
Testing the New O-Ring on 7.3 Powerstroke Water Pump
Once you’ve replaced the o-ring, it’s time to test your work.
- Start up your engine and let it run for about 10 minutes.
- Check for leaks around the water pump
- Look for signs of coolant leaking from any other part of the engine.
- If everything looks good, shut off your truck and let it cool down before doing anything else!
- Use the right type of O-ring. The o-ring you need to replace is a toroidal (don’t worry, that’s just a fancy way of saying “round”) style. Make sure you have the right one on hand before starting this job!
- Replace other parts at the same time. If your water pump is leaking, it may be because there are other worn or damaged parts inside your engine block that need replacing as well. Consider replacing these while you’re at it:
- Check for worn parts before starting any repairs–you don’t want to spend hours working on something only to find out later that another part needs fixing too!
