Egr delete questions

[dmax03]

I'm sure this has been discussed plenty of times but I want to get a straight forward answer. Should the coolant be flushed before or after the new oil cooler and egr delete are done? Seems to me like it would make most sense to do it before the replacement. I also plan to add a coolant filter.
What are the best recommendations for which brand of egr delete

Thanks guys

Do the coolant flush before and try to drive it a week or so before hand to get all that gunk caught in your old oil cooler. As for coolant filter I am going with a Sinister from RiffRaff Diesel.

Flush it before you install anything!!!! Then install your coolant filter and drive it for a month or two, and keep watching your EOT/ECT delta. Also need to change that coolant filter like every 1000 miles, cut them apart and see what is inside and once they seem to be pretty clean....Then install your new oil cooler and egr delete.

Ford is replacing my oil cooler. I work there and I'm having the mechanic do my egr delete at the same time on the side

agreed fllush with vc-9-(remove iron/scale) and restore plus-(remove silicates) before replacement and drive it around to get all gunk out. i went with defuser coolant filter. i would do the flush yourself with destilled water etc... awesome the dealer is doing it for you.

Agreed, do it beforehand.....and MAKE SURE they put an ELC coolant in, NOT the Ford Gold garbage. You might have to take it to them...

I flushed thoroughly before i did it and ran some vc9. Also installed sinister coolant filter. No problems with anything thus far. Get some gauges as well to monitor vitals if you havent already
