Yet Another Overheating Question
Well I'm victim to the fantastic cooling system in our 6.0s. I know there are numerous threads on the subject but I have yet to get any valid solution for my particular trucks mods and issues.
For the past few weeks I've been overheating after 45+ minutes of highway driving. (Needle hitting the red). The truck is internally eating coolant like no other. Coolant is disappearing daily. The overheating is very consistent to the point that if my destination is 1 hour away I know not to test my luck. Other than that, the truck runs fine around town and 45 minute or less stints on the highway.
With regular around town driving I am seeing my EOT @ 206* and ECT @ 200*. With highway driving (no towing) I'm consistently seeing EOT @ 220-223 and ECT 205-208. EOT/ECT is within 1*-3* of one another up until around 190*. So this leads me to believe my oil cooler is not the issue. The cooler has never been replaced while the truck has been in my possession from 115k miles to 124k miles (now).
I am already studded, egr delete and the head gaskets were replaced prior to me purchasing the truck. I'm also not seeing any coolant puke. The only thing that keeps headgaskets on my list is the fact that it is eating so much coolant.
I am not running a coolant filtration system and am running regular ford coolant. (lately with so much coolant disappearing i've had to improvise with water on the spot.) I'm unsure of how much of an affect this really is in regards to my overheating issues.
I'm getting on here to ask my fellow 6.0 owners to see if they have any insight before I bite the bullet and take a day off work to take it into the shop.
Thanks in advance for everyones help.
