Ok so before I get started on egr delete do I need to drain any coolant from the truck? I know I will loose some when I remove the cooler. Or can I just top it off after the job is done? Any idea how much coolant I will loose? And what type our trucks use? Thank you in advance for any help. Not a lot of info on this out there I've noticed

I drained about a gallon from the radiator. Did not lose any from the EGR cooler. Poured it back in when I was done and no issues.
I wouldn't put HOAT (Zerex G05) in there from what I've read. You need OAT. Color probably doesn't matter but Orange would be correct with OE I'm pretty sure.
I drained none, lost about half a gallon on the ground when I pulled the cooler. Topped up with some orange 50/50.
What’ve ya read, if ya don’t mind sharin?
Did ya break somethin open on or near the cooler when ya did that? Mighta broke the vacuum and got a lil bit out of it that way. Just channelin my inner plumber.
Some quick googling can shed some more detail on it, but basically boils down to not mixing different kinds of coolant together in the system. Keep OAT with OAT, HOAT w/ HOAT, and IAT/IAT. That includes not throwing the green stuff in, even though it says you can mix with any color on the jug. Mixing can apparently cause it to turn to sludge and the coolant loses its longevity and protective qualities.
i pulled mine off without draining any coolant. lost a little bit. once i hooked up all the delete tubes i started the truck and cracked open the bleed pipe to bleed any air, got up to operating temp then shut it off and let cool down and just refilled the reservoir. no biggie

Stick with OAT- it’s what comes from factory. HOAT are in SuperDuty and Duramax from factory I believe. The Best way I’ve read is how Ray with DRD does it and recommends which is symphon out all you can and put it in a clean container. Once you remove or swap parts then replace it with the fluid you pulled. Test drive it and check. In theory it should be the perfect level unless there’s a leak.
If if you want to just break it loose and have some drain feel free but fill the tank and test drive then check fluid level. It’ll burp and drain excess out the over flow tube if it’s over filled. Worst thing you can do is have too little
