Since my 4.8 swap the fans have not been "computer" controlled. The other night i was unloading my trailer and left the truck running. I didn't think about it overheating . Well it got hot. Engine coolant hot message came on gauge was at just about 260 i turned the fans on hi and drove it up the road to get the 40 degree air going through the radiator to cool it off. It cooled off right away, and i know it didnt get that hot. After i wired the fans to the computer (i have a 6.0 harness that was set up for clutch fan setup) i noticed the coolant was a little low. I put some coolant in at work, drove home and its low again. I dont see any external leaks. No milky oil, and its driving extremely well will smoke through 1st and spin into 2nd i just hope i its not anything like i am thinking...otherwise tax season will have to be very friendly so i can get the L76 going faster then i thought.

Also i might drive it back into work tomorrow and do a pressure test too just verify no blown headgaskets or warped head.

Keep a check on the oil. I have done this 2 times, to the point the truck would go into limp mode,(after breaking a belt, trying to get home...

 

It never got to that point, i caught it right away luckily i just cant explain the coolant level.
