EGR Cooler Leaking

My 2005 Powerstroke started blowing some steam out of the exhaust. Within a few miles it was pouring out. When I got it home, and let it cool down, I restarted it and water came pouring out of exhaust system, tailpipe and muffler drain hole. Now if I try to start it, it seems to go into hydro lock, but will eventually start. I purchased a bulletproof egr cooler and new oil cooler. Will this possibly fix my problem or is there something way more serious going on? No coolant in oil.

You may have failed hesdgaskets, to check to see if it is the egr cooler, park the truck so the nose is lower than the rear, even if you gotta jack up the rear . Let it cool down, pull out the egr valve and look inside the intake manifold for wetness/coolant. If it's wet in the intake manifold then it's your egr cooler that has failed along with the oil cooler is clogged up. You need to replace them both as well as do a coolant flush.

If you don't find wetness/coolant in the intake manifold, then it's a good chance that the headgaskets have failed. They may have failed due to a failed egr cooler. Your gonna need to do a compression leak down test to confirm the failed headgaskets. If I were you, I would not drive the truck with it hydro-locking, this may cause major issues and cost you alot more money.

Definantly the egr cooler. The Delete should fix it but if you keep running it like it is you will blow the head gaskets. I have one that I just blew the egr cooler on and waiting to be fixed

Yeah, if it is blowing liquid out of the exhaust and seems like it is trying to hydrolock I wouldn't even try to start it again. If you turn it over and do hydrolock it there is a good chance of serious internal damage.
