Were you seeing the coolant blowing out the coolant resevoir bottle on top of the engine near the firewall? A lot of folks have experienced this, even with stock trucks, including me when towinng heavy.

6.0 loosing coolant
Problem started about 2 months ago. Coolant was coming out of expansion tank.We are loaded heavy, Pulling a triple axle GN and grossing over 29,000. I know we are over but pulled the same load with a 2000 F250 with . This one is a 350 dually.
Things done to this point, replace tank cap, replaced fan, replaced thermostat. None of these thing helped. We would take it out after each of these fixes and put it under a hard pulland would loose one and a half to two gallon of coolant in 20 miles. They finally checked inner cooler per
Ford instruction and found that it leaked. So it is being replaced, bad news is they are back ordered for about 2 weeks. My truck is setting 1200 miles from home. Running without a load this truck does't have a problem, put it under a hard pull and it will get rid of alot of coolant. On the last trip out we had a deadline to be at a destination. In the first 300 miles of a 1200 mile trip and replacing the cap we thought it was fixed, then temp went up.It had gotten rid of 3 gallon of coolant. To make a long story short to finish the trip we went through 20 gallon of water. NOWTHAT IS WHAT I CALL A SERIOUS LEAK.

I never started having a problem losing coolant til I unplugged my EGR valve and towed with it. Predator 65hp level towing about 6000lbs. Even at that it only lost about an overflow tank full and never lost more after that, but I haven't towed anymore since I got to Austin either. Refilled to minimum mark and no more loss.

there isn't anything abnormal that we have noticed.We had a western diesel programmer on it that was (stock-70 and 100) After we lost the coolant the first time on the 1200 mile trip we shut it off and ran stock, (we usually ran 70HP) this helped a little but it was still kicking the coolant out when towing the trailer. Running with no load it looses very little. Don't really have any answer why it does it. Tech told me that ther could be a crack in the lines in the cooler that could open up when it heats up. Pulling hard it runs about 1200 0n the pyro boost or stock.

Yes it is a western Diesel and it works very good. Had no problem with EGT.They made 2 differrent one's for the 6.0.They are no longer in business as they have filed for bankruptcy. One was 70HP and the other was (stock-70-100) which I have. They did not reprogram the computer on the truck.They were all wired in under the hood and didnot modify anything in the Ford computer.
