one time loss of coolant

[thinbluline]

I got SCT X3 custom tuned by eric. of course when i got it, it ran it pretty hard just to see what it had. I have a good buddy that is the head diesel mech. at local dealership. I took it to him for an oil change. Popped the hood to see that some coolant had puked from the resevoir. Looked old and had dried up already. Not a whole lot, just looked milky white. Thought head gaskets at first, but we pulled some coolant out to allow for thermal expansion due to it runnin a little hotter with the tunes. Hasn't done it since. Think I had too much coolant for the hotter tunes?? It was filled to the max line on the resivoir. Any opinions???

You probibly just had too much coolant.sometimes the coolant will "burp" its way to the level it wants to be at. I keep mine at an inch or so below the min. line

Well......now it's done it again. I just pulled a 5000 # camper about 100 miles. On the way down, it was about 86 degrees outside. When I set up the camper, I checked under the hood and saw that it had puked coolant again. Not too bad, but enough to know what was up. On the way back, we traveled at night. No coolant lost. Truck ran great though, no power loss. EOT got to 210 and coolant temp. got to 202. I don't want to get a head gasket job unless i just have to. I'm hoping to replace the EGR cooler and oil cooler. Anyone have any advice.

Same problems here, EGR code is throwing on mine as well, dealer thinks that the egr cooler is sticking open and boiling the coolant in the resovoir and is going to replace the entire thing, I will let you know if it helps.

Sorry, I'm in the wrong forum, mine is a 08 6.4 , could be similar problem though.
