If your truck's put together right, and maintained, from the get-go, it won't breakdown "in the middle of no where"... :lol:
The only way to guarantee that it won't breakdown "in the middle of no where" is to never go "in the middle of no where".

I go above and beyond in maintaining my vehicles. Many people call me "anal" about vehicle maintenance. But "stuff" happens.

I have to agree with you txgp17,it doesn't matter what W/P you have if it's mechanical it can break where ever you are.

"Spin speed": The pump's RPM is more of a function of the pulley sizes rather than the actual engine speed, for a given engine/setup. In my case, neither the crank nor pump pulleys were changed from the original Ford configuration, therefore the water-moving aspect (i.e. pump RPM) is the same as the original pump.
Exactly the point. By not changing the pulley (and no pulley change is expected in this retrofit), the IH pump is being asked to spin at the original Ford pump's RPM. If the IH pulley and the Ford pulley are the same diameter, then the IH pump will now be operating at higher rpms than the T444e engine operated at, based on the torque/HP and governed speeds published by IH.

This is not a bone of contention, it is just another consideration when choosing to deviate from OEM.

BTW, the "Navistar" pump setup being sold as a "kit" on a certain vendor website is NOT a "factory" IH (Navistar) pump.

After a close examination of the pictures on the vendor site, the pump they are selling is almost guaranteed to be a cheap Chinese knock-off.

There are certain characteristic marks that are on a "real" Navistar pump, and theirs does NOT have them.

I would not expect a Chinese POS to have the quality of the real thing...nor the life expectancy.

THANK YOU!

It is good that people know what they are actually getting... even when it is marketed as an "International" part.

Purchased mine from the local IH dealer and installed December 2013. Still working fine. The hose is the flex hose from NAPA. ANY long hose would work in a pinch. Again, I did this mod exclusively with the hope that the pump will last longer than the original and the aftermarket ones I had before. Only time will tell but I feel it is a worth while endeavor. No one else should do this mod until mine fails and I report how long it lasted. That is unless you are comfortable working outside of the box like me.

I had a leak in the heater hose coming off the driver side at the rear of the engine. When pulling the clamp and hose off the fitting at the bottom the cheap ass plastic connector at the top broke off. I used a screwdriver to remove the rest of the fitting and put a 5/8" inch hose with a clamp on both ends eliminating the Ford engineered plastic fitting at the top. I am sure this is a better solution than replacing the plastic fitting. And if my hose breaks in the middle of nowhere,... I will replace it with a spare piece I have that can be sourced at any auto parts store.

I have always heard there are no guarantees in this life except for death and taxes ;-)

But I think we would all agree that if we did have to drive to the middle of nowhere that each of us would hope to make the drive in a well maintained vehicle.

I'm finishing up my install today and I am using the flex hose. I was also initially worried about roadside repairs and parts availability, but I solved the problem. I bagged up my old bolts and thermostat and tucked them under my hood in a nook by the battery. If the pump goes out on the road I can always switch back to stock. I've always inspect my hoses regularly during routine maintenance and never known one to have a catastrophic failure without warning, so I'm not too worried about the hard to source lower. I did my conversion for the filter and hotter thermostat. The cast iron pump's increased durability for me is nominal. The cost difference between factory style and the IH is relatively insignificant if you are replacing everything anyway and spend a little time sourcing your parts. The only other concern I have heard about the swap is how the engine's RPM affects of the pump. I'm no expert but I know both the IH and Powerstroke have the same coolant flow requirements as they are the same engine. The pumps both have the same dimensions and fin design meaning they have the same peak operational RPM. I think it would be reasonable to assume both engines have pulley configuration designed to keep the water pump at that ideal RPM, making overall engine speed irrelevant.

I think I will ultimately be satisfied with the swap and if not I'll share my experience. Side note I got all my parts from Rock Auto except the Gates lower hose which I found cheaper on Amazon for $30.

February 2016 and mine is still working without issues. It has lasted much longer than the 1 year or so I got from the CarQuest unit. Now lets see if it surpasses the ten years I got from the one that came installed at the factory in 2003.

Still working fine

July 2017 and still no issues with my conversion. I need to check my logs on when I last replaced the filter. I keep one in the rr quarter panel with the jack along with an extra belt. The WIX unit works fine. If it gets to clogged up it will weep at the seal telling you it's time to replace it. I think that happened once to me. If I happened to purchase a new to me truck with a 7.3 I would install this unit as a maintenance item right away.

WOW!
This thread is still alive.... after 6 years!

I posted this (under my old username). Glad to see people are still enjoying/debating the Navistar pump install.

BTW, mine is still running just fine! (Same one as in the original pics at the beginning of the thread...)

For comparison, I will report on my aluminum water pump. This was installed on 5/2/2018. It is AIRTEX AW4114 from RockAuto. It was installed along with Gooch flush, new thermostat, thermostat housing, fan, fan clutch, radiator, and Shell Rotella Ultra ELC. So far, no problems. It is working perfectly.

Does that pump have a built -in filter like the Navistar?
