I don’t have the tools or the knowledgeable to tackle it myself. I’d rather have someone that knows what they are doing look at it. With that being said, what are the chances it’s not and egr cooler and it’s worse? The truck runs fine otherwise. It was off the road for a bit, I put the coolant in, went for the ride and noticed it was gone and am assuming it burned it (due to the white cloud behind me) I haven’t touched the truck since then but want to now so trying to come up with a plan to see if it’d worth putting money into.
