  1. 6.0 Coolant pressurized in 10 seconds

    6.0L Problems Forum
    Got a stock 06 6.0 power stroke. The second the truck starts, the coolant tank starts overflowing with combustion gas. My question is can a head gasket failure be this bad? Warped head? I’m thinking injector cup broke its seal or cracked.
  2. Transmission high heat in 6.0

    6.0 Trannie problems
    I have a 2006 f250 6.0 and there was coolant in the transmission fluid. I had just got it back from a head gasket job with everything done. I am confused on what is causing the high heat.

  3. Degas leak

    General 6.0L Discussion
    Last week I bought an 03 6.0 and I’ve noticed since then that there is coolant leaking from the degas bottle. The bottle itself, oil cooler, and egr cooler have all been replaced within the past couple years and I have the paperwork showing it was done. Once I started noticing it leaking I...
  4. Primary Radiator Petcock drips when closed

    6.7 Motor Problems (2011-2016)
    I just drained a small amount of coolant to do the coolant testing. When turning the petcock back in, the cam engages and it turns the last 1/4 turn. At that time, it continues to drip very very slowly. Is this common; is there an area that needs to finish draining out after the petcock is...
  5. Orange coolant?

    94-98 7.3L General Powerstroke Discussion
    Bought a 97 F-250 with the 7.3 PSD. The coolant is orange. From what I am reading, there is no possible way this is correct and I need to flush it out and refill with green + SCA. Is there any correct coolant for this engine that is orange?
  6. 2008 F-350 King Ranch Degas/Coolant Issues

    6.4 Motor Problems
    I know...another one of these threads... From what I've found Degas tank overflow can be from the tee installed incorrectly, Degas bottle issues, cap failure, stuck thermostats, or head gaskets. Truck is deleted and has no small coolant line tee. Just got done upgrading cooling system: new...

  8. Multiple ECT sensors?

    99-03 7.3L Powerstroke Problems
    I recently noticed my coolant temperature was over 500 degrees Fahrenheit when I had just started the engine. Great! I replaced the ECT sensor. It's located just to the left of the thermostat housing. I attached a photo to be crystal clear of what I replaced. Now my temperature is reading...

    6.0L Problems Forum
    It's been almost a year since I got the truck. Bought it bone stock with 80k miles. I have since had to replace all eight fuel injectors with the fuel pump. I added the Edge insight to keep an eye on things, and then I straight piped the exhaust. I have put 25k miles on it since the summer and I...

    Newbie here. First post. I go out to start my truck in the AM, let it run until EOT and ECT are both at LEAST above 150. However, it doesn't matter how warm it gets, it won't blow heat in the cab. Ice cold air only. Until I put it in drive then bam, blows heat like normal (maybe even hotter...
  15. Leak at the top rear driver side of engine: Coolant or Transmission Fluid?

    6.4L Problems Forum
    Well, I thought I was done with leaks for a while after just replacing my radiator (Mishimoto) and updating the hoses. Now, there is a leak at the back of the motor. The fluid is red, but so is my coolant now. It seems to be water soluble with very little smell. I know the truck smells a...

  20. Normal 6.0 pressures?

    General Diesel Discussion
    2003 6.0 ERG delete, 4" straight pipe, 185k stock head studs and gaskets. Never programmed. It sits at 60 PSI fuel pressure and drops to 58 PSI when you really get on it (does drop at less than 1/8 tank of diesel). I don't think it's ever had the blue spring. :dunno: ECT and EOT stay at 180 all...
