EGR cooler is NOT failed, reusing concerns?

Redid my oil cooler, which I caused the partial clog by flushing. It hasn't been clogged long, I don't have any symptoms of EGR failure, EGR is sooty, but not sticky, and my motor is 7 years old with all the factory updates. SO, I was NOT planning on replacing my EGR cooler, as I monitor my deltas and I'll know before there is a catastrophic failure. Also, I'm using Rotella ETC red coolant, which was put in after the flush that clogged the cooler. So, I know the boiling point is up to where it is supposed to be, and was not likely to flash boil. So, is there any seals that I should replace or O rings or anything related to the EGR cooler that I have to replace due to removing the intake? I did not remove the EGR cooler from the intake, and I don't intend to if I don't have to. Thanks in advance.

NOPE. You're good to go. Unless the cooler itself failed, there is absolutely nothing wrong with reusing it. Probably wouldn't hurt to clean the carbon out of the EGR cooler core and EGR passages though, while you have it out.

When my first truck went in before I got it the Ford diesel mechanic checked it and found no leaks.
So they went ahed and reused it. I later got my hands on a BPD cooler and had a reason to remove
the intake and at that time I swapped the cooler and cleaned the intake of all the nasty oil and soot.

If you want to here is that TSB that you could look at to see how they test the cooler. Not
really hard you use compressed air and use some plugs and a plate to fill the cooler with air as you
place it under water and move it around to clear out any bubbles and then watch for new bubbles.

Cool. Thanks Sean. I'm thinking the same thing; reuse this one now, BPD later as time and budget allows. I'm already into this more than I was planning, but still under the dealership costs and I'm doing more!

I don't think you will. Excessive deltas don't always indicate impending EGR cooler leaks or failures....... If the EGR cooler is an OE cooler and I had it apart, I would either delete it or replace it with a BPD or other welded stainless steel tube type EGR cooler that cannot leak.

JMHO.......

Cheers,

Rick
