Large coolant leak -not through degas cap
2005 Excursion PSD
Large amount of coolant went out the bottom of the engine. Degas bottle was empty. Hard to tell where it came from but I'm guessing near the EGR cooler. Didn't come out of the cap, top of engine is dry.
Realize there are a thousand threads on this, but didn't find anything specifically like this.
Never had any temp issues, happened when parked overnight.
Given the amount, seem like a hose blew but can't see anything.
Thanks for the help.

That leaves things too wide open. EGR cooler is on the top of the motor but you said not top. Does the majority of coolant seem to be driver or passenger side? The other thing I can advise you to do is to fill the bottle back up and watch for a leak before you start the truck.

What I mean is the area around the degas is dry. Looks to be passenger side. I filled it up again last night and can't see a leak today but hard to tell because of the amount of coolant everywhere. Didn't have time to clean it up last night. The amount I put in the degas reservoir is still there this morning.

Sounding like the EGR cooler hose, or heater valve.
EGR cooler hose is difficult to see. It's down in here. Behind your blue CAC boot:
or around the heater valve, back near the firewall:

Those stupid Degas bottles are known to crack near the nipple on the bottom, also check the plastic "Y" in the hose underneath the bottle.

If you have to start the truck let it warm up it will put some pressure on the Coolant system
Just watch it like a HAWK be ready to kill it if it dumps coolant out

Have you filled the coolant system back up yet?? and started the truck let it warm up it will put pressure on the coolant system.
I had a Car that I went to the store and while I was inside store the Heater core Burst so it seems to me that after the car is warmed up and then shutoff the pressure Peaks.
I also drove my Dads older F-250 to work once when I was younger I drove an hour to work and shut the truck down and all the sudden it was dumping all the coolant onto the ground upon further investagation he had a peice of cardboard blocking the radiator it was winter and he only drove about 3 blocks to workevery day so no big deal for that but he never told me
So due to the couple experiances Iv had shure seems like the pressure peaks upon shutdown after it fulley upto operating temp

LOL--the WHOLE system has pressure after shutdown. There's no way to just isolate the degas. Lets don't even mention that the cap is the HIGHEST part of the system and water doesn't run uphill.
