I was reading through the Ford Service Manual and came across the statement below:

The oil cooler cover receives oil from the oil pump and cools it in the oil cooler, which is located underneath the oil cooler housing.
  • The cooler bypass valves open in the event that the oil cooler base and/or cooler becomes restricted.
2005 F-Super Duty 250-550 Workshop Manual

With a bypass valve, it seems like the only effect of a clogged oil cooler (oil side) would be hotter oil. It should not have an effect on the EGR cooler.

Still wondering what oil restrictions could occur (and why), or is it just a smart safety feature like the bypass on the oil filter. Are the flow passages that small in the oil cooler?

OP - Sorry for the hijack ......................

I'm with you Bis. I don't understand the reasoning of grampy on this one. The coolant flows through the oil cooler and then on to the EGR cooler. If the coolant passages in the oil cooler become clogged, then coolant flow to the EGR becomes restricted allowing the EGR cooler to overheat and eventually leading to EGR cooler failure. I'm not sure how clogging of the oil passages of the oil cooler (if it's possible) plays into the equation in regards to EGR cooler failure. The connection between oil cooler and EGR cooler revolves around coolant flow and not oil flow. Anything that can help maintain that coolant flow is a plus.

With that said, I'm a firm believer in coolant filters and the benefit they bring to the table based on experiences of users on this forum. It was the first mod I did to my ride and it should go a long way to keeping my oil cooler, EGR cooler, water pump, and seals happy.

You remove the pressure cap and insert the rubber cone on the tool into the opening. I can post the instructions for the tool when I get on another computer that won't freeze up when I try to download a PDF file. Or you can go to this site and download the Oct 2007 Iowa school bus flyer;

It doesn't mention any specific procedures to take to ensure the removal of air pockets and it doesn't list any "cautions" pertaining to it. I wonder if this is part of the unresolved issues between Ford and International or if the VT365 radiator/external components are different?

origcharger - I would love to read more on this if you can post links to more info!


2006 F-Super Duty 250-550 Workshop Manual
The "Radkitplus" appears to be a similar tool to the "Vac N' fill" The International /"IC Bus" dealer shows in their flyer.
We have both an E450 with 6.0 and an IC bus with a VT365, I don't see where the radiator/external components are significantly differant enough to require a differant procedure.
Neither the Ford or International owners manuals that I have access to say anything special about filling the cooling systems other than just the normal drain and refill procedures. This vacuum and fill procedure is what they have been advocating to us at recent meetings and its how they do it on the assembly line.
Internationals main gripe about the 6.0 Powerstroke seems to be that Ford did not provide a means to capture how many times the computer has been "reflashed" to stock programming for warranty cost control purposes.

My 1st coolant filter plugged up at 300 miles and the 2nd at around a 1000 miles. Have been good since. Maybe my engine had more sand in it than most, I don't know. I do believe that I did my engine and any related cooling components a big favor by installing the coolant filter no matter what anyone says. By the way, my overflow bottle is crap free.
P.S.-- I do have a lot of respect for GrampyJims knowledge but difference of opinions is what makes the world go around and this a great site for discussion.

The photo's at dieselsite.com showing the "after pictures" are ones that I submitted for all to see.

My first filter went pretty quick and even the second one did... and that was after I flushed my system with distilled water and did a 100% coolant flush!!!

Here is the link to their page and my photos.

Worth every penny spent and should be the first mod people buy!!!
