Truck puked coolant for the first time.....
Need a little help/advice here guys.....
I was coming home from MI on I-75 the other day and the I hit a pretty good size hill near the KY/TN line. The truck got a little hot going up the hill and started puking coolant out the degas tank. The max temp on the DashDaq was 226-227 and the warning goes off at 225 (I was watching the temps like a hawk). Is was only above the 225 for 60 seconds or so and the engine fan kicked on right away. As soon as I let off the throttle the temps dropped pretty quickly and went back to their normal levels. I still had 4 hours of driving to do and the rest of the trip went fine and all the temps stayed where they normally do going through the hills of north GA.
Here are the details on the truck and my normal running temps,
2008 F350 auto, 4.10 gears and 75,000 miles
Spartan 210 towing tune
DOC & DPF Delete
Pulling a 48' enclosed trailer that weights 15,150 lbs (I ran it across the scales)
EOT - 200-210
ECT - 200-205
Trans Temp - 175-180
My question is did I hurt something or did the truck get a little too hot and tossed it's cookies until I let off?? The coolant level before this happen was just above the rubber hose on the side of the tank and that's where it's been since about a month after I bought it. As it sits today the tank is almost empty. I had the radiator flushed back in March and it’s still the original radiator.
Any help and/or advice would be greatly appreciated and if needed I’ll put it all back to stock and take it in for a check-up
PS. I normally run the 250 tune when I'm not towing and it's never done this in the 3+ yrs on the 250 tune. It didn't even do it last yr when I raced it for the first time.
2008 F350 Lariat - 6.4L Auto, Crew Cab, DRW, long bed, 4x2 and 4.10 gears. Mods - ARP Head Studs, EGR delete, DOC/DPF delete, S&B Intake and Spartan tuning.
