Thank you, great source of data and knowledge. Appriciate the hard work you put into this site. One thing you may want to add on there too is about replacing the coolant overflow cap with an after market one that will maintain higher PSI in the system. Also when I did my coolant flush prior to putting bypass fitler on. I used two Cummings products to flush the system. Restore and Restore plus. One is a degreeser and the other is a descaler. Great products to really clean the whole system out, especially the silica from the Ford Gold Coolant in the oil cooler. Again THANK YOU, GREAT SITE! will reccomend to friends!

Thanks for having this great information available to those that would like to do their own maintenance. I bought a one owner 2000 F250 7.3 with 129K miles on it and looking forward to running it to the million mile mark.

Hello, in reference to the Donaldson AIS filter installation, this is the third one i've installed,
on a '99 7.3, F350,4wd, DRW,i pushed the long intake snorkle along the frame rail past the intercooler and it came to a stop, apparently there was a fiber flap blocking it, this never happened on '99 F250 or '02
Excursion both 7.3/2wd, it was simple enough to cut the fiber but this caused me to notice there is an ABS partition that funnels air toward the radiator only inches away from the snorkle inlet opening, this plastic sidewall completely blocks air travel into the snorkle, all 3 trucks share this condition!
I'm contemplating removing the grill, and using a 4" holesaw to create an opening, allowing air moving at road speed a free path into AIS, I'm no genius and ask
what others have done.
Thank you, mikeG

I just bought my first ford, my first f250 superduty, and my first diesel period. My truck is a 1999 with the 7.3. I am doing research on the maintenance that needs to be done and ran across your site. Thanks for documenting so much. Great site. Since I am not sure when filters were last changed, I thought I would start there. If you have suggestions on things I should do to this new-to-me truck, I'm all ears. Thanks!

Hi Daniel
Just keep up with the routine stuff and the rest will follow. These are good trucks. Thanks for posting.

I enjoyed reading your site. I never had a Super Duty but did run a '94 7.3 IDI diesel quite a few years. Rebuilding the injection pump at 102k. My stock 7.3 IDI never got wonderful mpg. The E4OD behind my 7.3 IDI died at 160k. Rather than put money into another E4OD I replaced the 7.3 in my '94 F-250HD in April of 2009 with a new from the factory RECON '93 EPA certified Cummins 12 valve 180 bhp unit. Adding a new (not rebuilt) Allison AT1545P which has lock-up in fourth gear behind the 5.9. The truck is a great rig on highway rig. I replaced the 3.55 ring and pinion gears with a new Ford 3.08 rear end gear ratio. I spent countless hours of research on this engine / transmission combo. Figuring if I was going to drop some big coin that I may as well do it right building a truck that has the longevity of a commercial rig verses a consumer grade unit! For a strictly on highway rig, the only thing I would have done differently in hindsight is I would have went with the Cummins 3.9 liter instead of the 5.9 which is overkill for my application.

I too bought my 2000 F-250 7.3 off the lot and had no idea it would be such a great truck. Came across your site today looking for torque specs. Thank you for all the great information. Its interesting how we both have made many of the same modifications. I changed my coolant to Evans - no DCA, no pressure, never change - its worked out really well.

I stumbled upon your site and must say it's a bookmark for sure. If I ever need anything listed I'll use your link. I love your pictures a write-ups. The extra things listed like the torque calculator, values and what not are fantastic. It's like a one-stop shop for great information!

Excellent write up on the superduty ball joint repair. I used it for my 2002 excursion. Thanks!
