EGR Delete-Why rebuild oil cooler

Hey all, i'm relatively new the powerstroke and i have a general question about the oil cooler. i deleted the EGR a while back and i was under the impression that i was good to go. now from reading different posts i'm getting the feeling that my oil cooler can still fail. for some preventative maintenance should i also have my oil cooler rebuilt? thanks for any input you all may have. God bless.

Not rebuilt, replace it.

I dream of a better tomorrow, where chickens can cross the road and not be questioned about their motives.

no, rebuild it. you knock the heat exchanger portion out of the housing and replace it. much cheaper than buying the entire thing.

Not quite, while you have prevented the coolant from being dumped into the cylinders and blowing your headgaskets, you have not stopped the cause of a clogged oil cooler and breaking down the oil from overheating.

You have two options, first moniter your ECT/EOT temps and rebuild the oil cooler (kit from Ford runs around $200) everytime the delta gets around 15*. Second, conduct a complete coolant flush with Restore (removes silicate deposits), then Restore Plus/VC-9 (removes the scaling and junk) rebuild that oil cooler post-flush, pre-fill and fill that system with a silicate-free ELC. (Ex: CAT EC1 rated)

Removing the silicates from the coolant is the only way to ensure you don't plug the cooler up. The EGR delete, just prevents the coolant from getting in the intake with everything lets go.

alrighty...great info everyone. i appreciate the responses. My delta runs anywhere from 6-10* depending on conditions so i think it's still good but i'll keep an eye on it. i'm definitely planning on doing the coolant flush here within the month tho. again, i appreciate the responses.
