I just installed this yesterday. After it got up to temp after initial installation I noticed a small leak in a prestone flush valve on the heater hose, I shut it down and replaced it tonight. Again fired it up and brought it up to temp. Once nice and warm I checked for leaks, no leaks. Jumped back in the cab and gave it some gas before it even got to 1500 RPM's Boom
This is what I found
