COOLANT DISAPPEARING
OK SO I HAVE SEARCHED THIS FORUM ON THIS SUBJECT BUT NO REAL HELP. I HAVE PUT 5 GAL OF ANTIFREEZE IN TRUCK OVER THE PAST COUPLE DAYS. NO SIGN OF NONE LEAKING. NOTHING SHOWING IN OIL. I JUST DONT KNOW. SOMETIMES YOU CAN SMELL IT OUTSIDE OF TRUCK. ANY IDEAS.

5 gal is way alot. I would triple ck too make sure its not in your oil. If its not in your oil then its getting mixed in with your fuel. You might have an injector cup or cups thats leaking. Does your coolant smell like diesel fuel?

But if that was the case it would be filling the coolant as opposed to emptying it. When injector cups cause problems it's always fuel in coolant, not coolant in fuel because of the higher operating pressure of the fuel system. Hope this helps.

I was thinking cracked degas tank that is leaking on to the fan under pressure and evaporating............................
if that is the case a cooling system pressure test would tell the tale.

Ok system hold pressure fine and no white smoke. No water in oil at all and nothing in the coolant.

So your oil level isn't moving up, no white smoke and ( obviously) their isn't anything leaking...how long did you watch for a pressure drop on the coolant system and how much pressure? it has to be going somewhere....subscribed, this is an interesting one w/ that much coolant loss.
