@@adrienst.raymond6801 I’m not positive that it is a 7.3. I was only going by the head bolt size which is 1/2”. I’m not sure how accurate that is for telling what engine it is though. Do you know any other way to tell?
@@MountainMindset I know the bore of the 7.3 cylinders is 4.11”, I think you’re right with the 1/2” head bolts though. I know the 6.9 had smaller head bolts and that was the weak point for those engines, I just don’t remember the exact size. 87-88 was the transition from bullnose to brick nose as far as I know for the obs fords, I’m just not if that was also the transition from 6.9 to 7.3
@@adrienst.raymond6801 I should have measured the bore while I had it apart! I didn’t even think about it. 🤦♂️ Lol. 7/16” is the 6.9 head bolt size if I’m not mistaken. Seems like 87 or 88 was the 6.9 to 7.3 transition too. I’m not sure either. 👍🏻
Id bleed the air out of the upper radiator hose and see if it gets better. Kinda looks like the top of the radiator is higher than the overflow.
@@TheDisorderly1 good idea! I’ll do this when I take the thermostat out! Seems like it needs a cap on top of the radiator. 🤷
Check out either Tom Woods or East Coast Driveline for custom work.
@@adrienst.raymond6801 good to know👍🏻
seem like thermostat is stuck shut
@@jamesrives8384 I thought about that while I was editing this video. Lol. I’ll take it out and see if it makes a difference! 👍🏻
Would recommend throwing that thermostat in a pot of oil on the stove with a digital meat thermometer. When they get old they like to get sticky
That’s a 6.9 Idi filter housing, are you certain it’s a 7.3?

So what lol filter housings are changeable, I'm currently running a 6.9 filter head on my 7.3 lol
