Oil Cooler O-ring replacement help

superjoey03 · #1 (**permalink**) 12-31-2010, 09:18 AM

I am looking for detailed instructions for replacing the o-rings in my oil cooler. I have an 03 f350 with a 7.3. I have searched the forums for a while and cant seem to get any step by step detailed instructions. I am very mechanically inclined but as with some of the users here this is my first diesel and i want to learn these kinds of things to do my own repairs. I hate paying for something i can do myself. Any help is greatly appreciated.

You just unbolt it, tap the ends off with a rubber mallet (might need a hammer). 2 big orings on each side. Tap the ends back on, bolt back together, good to go. Its really simple.

^^^ pretty much summed it up - your gonna get dirty , drain coolant and oil first , watch for cross contamination , maybe leave oil pan bolt out to remove any coolant that gets in oil when disconnected
