Hey y'all, how's it going?
Well I just put a new coolant reservoir in my truck on Friday. The old one was all gross and had a few hair-line cracks in it. So I figured what the hell, might as well replace it.
I've always had a coolant loss since I bought the truck in April. Before it was leaking somewhere, and then the leak just magically stopped. Now the coolant disappears. While trying to burp the cooling system of any air bubbles the other day with the install of the new reservoir, I discovered I have a ton of back-pressure on the cooling system.
So I'm thinking great, cracked heads. I mean the truck already has ARP studs, so it has to be that right?
Well the only problem is, is I have only those 2 symptoms. Loss of coolant, and a lot of back-pressure on the system. My cap does hiss obviously because it's venting but it doesn't puke like you would typically see.
I have heat at idle when I'm at operating temp, no white smoke, and no oil in my coolant. Just this mysterious coolant loss.
Too my knowledge (dealer's word here) I have an EGR delete. I have no idea how to check and see if that's true or not. Could someone maybe tell me how to identify the EGR by looking in the motor? I looked kind of under the turbo and I don't see anything there but maybe there's another way to check? Also with the EGR valve can I just take it out and inspect/clean it? I'm honestly too lazy to go and buy o-rings for it (broke as hell, too!) but I always see you need to replace the o-rings whenever you take the valve out. If they o-rings are fine, why replace them? I know if I remove the valve I can then check the intake and see if there's any coolant in there which would point to an EGR failure (if I even have one!!!).
Anyway, has anyone else had a mysterious coolant loss, with no obvious leaks and high coolant system pressure and it NOT be the heads? Maybe a crack in a hose or something? Radiator issue?
Also if it helps whenever I unpressurize the cooling system by removing the cap, it bubbles a little bit like there's an air pocket somewhere.
I'm too broke to fix it if the damn truck needs heads, and if it does, off to a dealer she goes on trade towards a cummins
Also if anyone could run an OASIS report on my truck shoot me a PM
EDIT EDIT EDIT:
Well last night I parked the truck and went to bed. Today I woke up to this
So I did some reading about the EGR orange hose, even though I was pretty sure I bought it with a delete. So I climbed up on top and looking down on top of the engine it's wet with coolant. It's like that on both sides. Here's a pic on the passenger side, right under the turbo where orange/blue egr hose would be. I think that black hose is going into the oil cooler?
Anyone have any ideas? Also isn't that where I would see an EGR if I had one?
Forgot to mention, it's leaking on both sides underneath.
