Now I had all these mods for some time now and the truck was running great, just recently it started overheating, it first started when I was pulling my travel trailer up some hills (trailer is a 25' about 6500lbs, don't even now I'm pulling it) but now it heats up even when I'm not towing and it will vent out the degas bottle and sometimes over heat to the point of venting coolant down the side of the truck.
2 different Ford dealerships did a bunch of tests and found nothing, had my cooling system flushed & press tested for leaks and I had my thermostat changed as a process of elimination,even with my chip uninstaled (truck back to stock) it does the same. pulled my inter cooler out today and had a look to see if the rad,inter cooler, A/C cooler were plugged up...but found nothing... I have just over 70,000km on it...I have a lot of people scratching their heads over this one...
