Checked things over and drove it to Omaha over the weekend for kind of a test run.
And right after I took the pic I was like "crap a puddle!" So I pop the hood and start looking for what it is. Right there it can only be coolant or engine oil.
Oh crappity crap crap crap. That is going to hose the Indiana trip...
So we go eat and I pretty am pretty much counting the truck out going to Indiana. I have to gut the thing like a fish to change the radiator and I can't afford the radiator I want at the moment.
I let it cool down and go to pull the cap off to see how much coolant I lost... and the cap is loose. Cap position is approximate, the first thing I had to do was see how loose it was.
When the cap is tight it has the script parallel to the side of the radiator. It has to be on a certain way, it bugs me if it is the other way.
So I get to looking, the tab under the overflow hose is wet. That side of the filler neck also wet. And between the rake of the truck and the slope of the driveway if you follow it down it lines right up with the lower internal tranny cooler fitting.
Not sure I really lost much of any coolant at all, I was not leaving a trail. Current theory is after I shut the truck down the resulting temp spike opened the cap and instead of pushing coolant into the puke tank it dribbled it thru the unsealed cap. I drove it an hour+ back home, the cap was tight and everything is still dry.
It was 78-72* on the way home according to the mirror mirror on the windshield, gorgeous driving weather. It is amazing how much better the thing drives between a fully functioning rear suspension (no stuck shackle) new shocks plus the rear sway bar... it goes down the road amazing. The speedometer even ran smooth the whole way home.
I just wish I could get new tires on it but I don't see that happening anytime soon.
